Repeat failure diagnostic
Separates a hardware grade problem from a frame problem using the failure count, the component, and the grade marked on what is fitted now — because the second identical failure is data, not bad luck.
Pick the component and the count; the decision rules applied are printed in full below.
| Evidence | What it points at |
|---|---|
| Second identical failure on one opening | A specification question, not a procurement question — the tier or the frame, not the brand |
| Grade 1 unit failing early | Sizing, mounting or the frame. A closer undersized against wind or stack pressure, or an exit device fighting a misaligned strike, consumes itself regardless of grade (A156.4 Grade 1 closers are tested to 2,000,000 cycles; A156.3 Grade 1 exit devices to 500,000 with preload) |
| Grade 2 or 3 on a high-cycle opening | Tier below the traffic. Step the grade up rather than replacing like with like |
| Lockset failing repeatedly | Check the grade tier under ANSI/BHMA A156.2 (bored) or A156.13 (mortise). No cycle figure is quoted for these because published sources disagree on the current Grade 1 threshold |
| Butt hinges sagging again | Each set holds less than the last as the screw holes give up; a continuous hinge spreads the load down the full edge and is the usual answer after two sets |
| Frame flexes when the door is pulled hard | The frame is the job. Hardware bolted to a moving frame fails again, whatever its grade |
To tell grade from frame apart on site: pull the door hard and watch the frame — movement means anchors; look for a strike with bright rub marks wandering off its original footprint; check whether the door still latches when released from halfway open. Any of those points upstream of the hardware.
If the same part has failed twice, the part was never the problem
This is the one page on this site organised by component rather than by where the opening sits, and it exists because of a specific pattern: a building replaces a closer, the closer fails, the building replaces it with an identical one, and the cycle repeats until somebody decides commercial hardware is simply poor quality.
It is nearly always a grade and sizing problem. Hardware is tested and graded against cycle counts under the ANSI/BHMA A156 standards, and the tier a building was fitted out with was decided by a budget years ago, against an assumption about traffic that may never have been true and certainly is not true now that a tenant changed.
So the useful question on a repeat failure is not which brand to buy. It is what the opening actually runs at, and what tier of hardware that traffic implies.
A large share of that pattern lands on exit devices, because a panic bar is the busiest single component in most buildings and the one most often swapped like for like without anybody asking why the first one went. Those have their own section further down.
Hardware we replace and why the grade matters
Component replacement on openings anywhere in a Charlotte building, whether or not the opening falls under one of the other five lines. Where the underlying fault is a frame or a leaf, you will be told that instead of being sold hardware that is going to fail again.
Door closers
Graded under ANSI/BHMA A156.4, where Grade 1 means two million tested cycles. That number is not a promise about your door, but it is a useful floor: a Grade 1 closer failing early on an exterior opening usually means it was undersized against wind and stack pressure rather than defective. Sizing gets worked out against the actual opening — leaf width and weight, exposure, and whether the door has to meet an accessibility opening force limit at the same time as latching reliably.
Exit devices and panic hardware
Graded under ANSI/BHMA A156.3, where Grade 1 requires five hundred thousand cycles with a preload applied to the door — a requirement added in the 2014 revision that made the test considerably harder and means some older Grade 1 certifications would not pass today. On a genuinely high-cycle opening, a rebuild kit for a Grade 1 device is frequently better value than a new Grade 2 unit, and that is worth pricing both ways.
Locksets and cylinders
Bored and preassembled hardware falls under ANSI/BHMA A156.2 and mortise hardware under A156.13. We do not publish cycle figures for these because published sources disagree on the current Grade 1 threshold, and quoting a number we cannot stand behind would undermine every other figure on this site. What is not in dispute is that the grade tier is the thing to check when the same lock has failed twice.
Hinges, and when to stop replacing butts
A high-cycle leaf will work through sets of butt hinges and each replacement buys less time than the last, because the screw holes in the frame and the leaf edge are progressively less able to hold. A continuous hinge distributes the load along the full height of the door and is the standard answer once an opening has been through two sets. On labelled assemblies whatever goes on has to be listed for use on a fire door.
Panic bars and exit devices
A panic bar — an exit device in the catalogues, a crash bar on most sites — is not a lock with a bar across it. It is a latch mechanism that has to release under a single motion from the inside whatever is happening on the other side of the leaf, and it carries that requirement through hundreds of thousands of tested cycles. That gives it failure modes a lockset does not have, and it makes ‘it still opens’ a poor test of whether it is working.
It opens, but the door will not latch
The most common call on this line, and usually not a fault in the device. The latch is no longer meeting the keeper squarely, because the leaf has dropped on worn hinges or the strike has shifted on its screws. Fitting a new device without moving the strike buys nothing at all.
Strikes, keepers and where the tolerance goes
A rim device latches into a surface strike, a mortise device into the frame, a vertical rod device into the head and the floor. Each has a small window it works in and each loses that window in a different direction. The check is done closing the door slowly by hand rather than pushing it shut and listening.
Loose chassis, rail and end cap
The bar takes a shoulder or a cart every working day and the fixings into the leaf work loose. Once the chassis can move on its mounting the touchpad travel changes and the latch stops retracting fully. Tightening into holes that have already opened up lasts weeks; sound fixings into sound material is the actual repair.
Vertical rod devices
Top and bottom rod devices have more to go out of adjustment than a rim device does, and they are the ones most often found with the bottom rod disconnected because it had started catching. Disconnecting it changes what the door does, and that ought to be a decision somebody made rather than something discovered later.
The closer is part of the exit device problem
A device cannot latch a door the closer has not driven home. On exterior and stair openings a closer undersized against wind or a stack pressure difference will present as an exit device fault every single time, and a new device will not touch it.
Impact damage, rebuild or replace
Struck end caps, bent touchpads, a rail that has been forced. Where the chassis is sound and the device is a Grade 1 unit under ANSI/BHMA A156.3, a rebuild kit is the smaller invoice and often the better outcome. Where the rail or chassis is deformed, it is a replacement and gets called one.
Panic hardware and ordinary locks are not swaps
A lockset can be in perfect order and still be the wrong thing on an opening that has to release under one motion, and an exit device is not the answer to a door that simply needs a better lock. Which one an opening should carry is a question about what the opening is for, and it is worth settling before parts are ordered.
One habit worth naming: a device dogged down through the working day is not being tested, so a latching fault stays invisible until the first evening somebody dogs it off. Mechanical dogging is also not available on devices listed for use on fire door assemblies, which is deliberate rather than an oversight. Where the opening is a labelled stair or corridor door, latching is the entire point of it and what those assemblies have to do covers the rest. Where it is a public entrance, the closer and the pivot underneath are usually part of the story — that is the entrance and vestibule line.
What changes a hardware figure
| Variable | Effect |
|---|---|
| Grade tier being fitted | Direct. A Grade 1 device costs more and lasts long enough that on a busy opening it is usually the less expensive decision over five years. |
| Rebuild versus replace | Often large in favour of rebuilding, where the existing device is Grade 1 and the chassis is sound. |
| Whether the assembly is labelled | Restricts what is permitted, which can rule out the obvious part. |
| Whether the frame or leaf is the real fault | Decisive. Hardware fitted to a moving frame will fail again and nobody should be paying twice to learn that. |
Parts are named on the job. If you would rather buy them yourself and have them fitted, that is a normal request here.
How hardware decisions get made
Repeat failures get treated as a specification question
Not as a procurement question. The second identical failure is data, and it is usually saying the tier was wrong.
Grades get cited with the standard attached
'Grade 1' means nothing without the A156 number beside it, because each standard sets its own threshold.
Closers are sized rather than matched
Fitting the same size as the old one is only right if the old one was right, which on hard-used openings it frequently was not.
Rebuild is offered where rebuild is better
It is the smaller invoice and it is often the better outcome, which makes it worth saying out loud.
Numbers we cannot verify are left out
Where published sources disagree on a cycle threshold, no figure gets stated. That gap is deliberate.
The frame gets ruled out first
Because hardware bolted to a frame that moves is money spent on a symptom.
How a hardware call runs
- 1. What has failed, and how many times
The count matters more than the symptom.
- 2. What is on there now
Manufacturer, model and grade if it is legible. Most hardware carries enough marking to identify it over the phone.
- 3. Rule out the frame and the leaf
Before any part is quoted. This is the step that gets skipped and it is the step that decides whether the replacement lasts.
- 4. Grade specified against actual traffic
With the standard named, the tier explained, and the rebuild option priced alongside where it applies.
- 5. Fitted, adjusted and tested at the opening
Including latching from half open and, where accessibility applies, checking opening force and sweep timing with a gauge and a watch rather than by feel.
Questions that come up on this line
Is a panic bar the same thing as an exit device?
In practice yes. "Exit device" is the catalogue term, "panic bar" or "crash bar" is what buildings call it. The distinction that does matter is between a device listed as panic hardware and one additionally listed for use on a fire door assembly, because the second is not made with mechanical dogging.
The exit device opens fine but the door does not latch. Is the device faulty?
Usually not. Most of the time the latch is no longer meeting the strike squarely, because the leaf has dropped or the strike has moved on its screws, or the closer is not driving the door the last inch. All three cost less to correct than a new device, and all three get checked before one is quoted.
Can a panic bar be rebuilt instead of replaced?
Often, where the chassis and rail are sound and the device is a Grade 1 unit. A rebuild kit is the smaller invoice and on a genuinely high-cycle opening it frequently outlasts a new Grade 2 device. Where the rail or chassis has been deformed by impact it is a replacement, and you get told that rather than sold a kit that will not sit right.
The same exit device has failed twice in two years. What does that mean?
Either the grade was wrong for the traffic the opening actually sees, or something the device is bolted to is moving. A second identical failure is data rather than bad luck, so the frame and the leaf get ruled out before a third device goes on.
Do you inspect or certify exit hardware?
No. We service, adjust and replace it, and we will say when something in front of us would not pass an inspection. The inspection record itself wants an inspector whose qualification the authority having jurisdiction will accept, and producing that document is a different job from repairing the device.
