Embedded Files
A door project often collapses at the very last detail.
The finish looks perfect, the hinges align, the closer glides—and then the inspector points to the horizontal bar and says, “That won’t pass.”
The reason is rarely the brand; it’s usually a mismatch between the door type, occupancy use, and the safety code behind it.
Scene Check — One Quick Way to Define the Requirement
Scene Check — One Quick Way to Define the Requirement
Take a sheet of paper and write down how the door is used and who passes through it.
Public areas, schools, theaters, hospitals, hazardous zones → usually require a push-to-open exit device.
Staff-only areas or non-egress doors → usually exempt.
Any door that might serve as an escape route → treat it as mandatory.
This first split between critical and non-critical doors saves hours later when you reach the hardware stage.
The Door Itself Decides the Mechanism
The Door Itself Decides the Mechanism
Label each door by structure: single, double (with or without mullion), glass or narrow-stile, fire-rated or not.
Single leaf → choose a rim device.
Double leaf without mullion → go with surface or concealed vertical rods.
Single door with higher security demand → use a mortise model.
Fire-rated door → install fire-exit hardware only; mechanical hold-open (dogging) is not allowed.
Glass or slim frames → prefer concealed solutions to avoid drilling through metal edges.
Once this step is clear, installation, hardware matching, and maintenance become predictable instead of painful.
The Small Details That Decide a Pass or Fail
The Small Details That Decide a Pass or Fail
Inspectors almost always look for the same items:
The bar sits between 34 and 48 inches (865–1220 mm) from the finished floor.
The active push area covers at least half the door width.
One push releases the latch—no keys, twisting, or force.
No chains, padlocks, or surface bolts block operation.
If tied to access control, the system must release immediately during fire alarm or power loss.
These few details decide whether a door passes in minutes or holds a project for days.
Electric Versions Work Brilliantly When Wired Correctly
Electric Versions Work Brilliantly When Wired Correctly
Modern projects favor electric latch retraction, delayed egress, and controlled egress versions.
They integrate beautifully with card readers or alarms—but only if the wiring respects the life-safety rule: when the alarm triggers or power drops, the door must open freely.
A single line on a wiring diagram—“fail-safe release on alarm”—makes the difference between approval and rejection.
Sourcing Decisions That Save You Trouble
Sourcing Decisions That Save You Trouble
Many teams now mix local and overseas supply.
If you plan to import or customize finishes, two items matter most before shipment:
Latch size and fire-door labeling on the sample photo or spec sheet.
Air-freight from Asia usually takes about a week, faster than many regional restocks.
Write the finish color, electric option, and control interface clearly in the PO—no ambiguity, no surprises.
A Quick Matching Card
A Quick Matching Card
Fill in three short lines for each door, and the correct hardware choice almost reveals itself:
Door + frame: single / double (with or without mullion) / glass or narrow-stile / fire-rated Y or N.
Use + traffic: public, high-occupancy, or staff-only.
Control: mechanical only, or connected to access control / alarm system.
From that:
Single → rim type.
Double without mullion → surface or concealed vertical rod.
Fire-rated → fire-exit model, no mechanical hold-open.
Access control → ELR version with documented fail-safe release.
Frequent Trouble Spots
Frequent Trouble Spots
A mechanical hold-open device installed on a fire-rated door.
Mounting height or bar width outside code limits.
Extra locks or bolts added on an egress door.
Access-control wiring that keeps the latch engaged during alarm.
Double doors without mullion using single-point latching, causing misalignment after use.
Actions That Can Be Done This Week
Actions That Can Be Done This Week
Walk each escape path with a tape measure and tag every door as public egress, staff, or non-egress.
List every fire-rated leaf and match it with certified fire-exit hardware.
For doors linked to access control, collect wiring diagrams and confirm fail-safe behavior.
Build a simple spreadsheet: door → device type → accessories → compliance notes.
Next project, you’ll already have the template.
