You can understand every component we've covered in this series — frames, doors, hinges, locks, closers, access control hardware — and still install the wrong thing on the wrong opening if you can't read the schedules. The hardware schedule and the door schedule are the two documents that translate the specification into specific products at specific locations. They're where the project lives in the field, and misreading either one is how correct products end up in the wrong places.
This final article in our Contractor and Facility Manager Education Series is a practical guide to reading these documents — what they contain, how they relate to each other, and where the most common interpretation mistakes happen.
What the Door Schedule Is
The door schedule is a tabular document — almost always included in the architectural drawings — that lists every door opening on the project, typically identified by a number or mark, and provides the key physical information about each opening: size, material, core type, fire rating, and any special construction requirements.
A typical door schedule row includes: the door mark (a number or alphanumeric code that corresponds to a location on the floor plan), the door width, height, and thickness, the material and gauge (hollow metal 16 ga., wood particleboard core, etc.), the fire label requirement (if any), the frame type, and notes for special conditions — vision lites, louvers, special hardware preps, undercuts, or other deviations from the standard opening.
The door mark on the schedule matches the door mark on the floor plan. When you're standing at an opening on the job site and need to know what goes there, the floor plan gives you the mark, the mark takes you to the schedule, and the schedule tells you what was specified for that opening.
What the Hardware Schedule Is
The hardware schedule is a separate document — often included in the project manual (specifications) rather than on the drawings, though some architects include it on drawing sheets — that lists the hardware sets for the project. A hardware set is a group of hardware that applies to a category of openings, and the hardware schedule assigns each door mark to a set.
A typical hardware set entry lists: the set number, the doors it applies to (by mark), and then each hardware component in the set — manufacturer, product number, size, finish, and any special notes. It reads something like:
Set 3 — Applies to doors: 105, 107, 1123 hinges — McKinney TA2714 4.5 x 4.5 US26D1 cylindrical lockset — Sargent 8204 LNL function F05 US26D1 door closer — LCN 4040XP size 4 6891 door stop — Rockwood 409 US26D
Every opening on the project should have a hardware set assignment. The hardware schedule is the document that proves the right products were specified for every door. It's also the document that gets reviewed and approved during the submittal process — so changes from the original specification show up there.
How They Work Together
The door schedule and hardware schedule are meant to be read in parallel, not independently. The door schedule tells you the physical opening; the hardware schedule tells you what operates it. Used together, they answer the complete question for each opening: What is this door, and what goes on it?
A common field workflow: you're installing hardware at door 112. You check the floor plan — door 112 is in a specific corridor. You go to the door schedule — door 112 is a 3'0" x 7'0" 16 gauge hollow metal door, fire rated, no vision lite. You go to the hardware schedule — door 112 is in Set 3 (as in the example above). Set 3 tells you the exact products to pull and install.
That workflow depends on the two documents being consistent with each other and with the physical door and frame you're looking at. When they're not consistent — which happens more often than it should — that's where installation problems start.
Hardware Finishes
The finish code on a hardware schedule deserves specific attention because it's easy to overlook and expensive to get wrong. Hardware finishes follow ANSI/BHMA designations: US26D is satin chrome, US32D is satin stainless, US10B is oil-rubbed bronze, 689 is equivalent to US26D in aluminum, and so on. Every piece of hardware in a set should carry the same finish code unless there's a specific reason for a deviation (some closers, for example, come in a limited finish range, and a closest available match may be noted).
A set where half the hardware shipped in US26D and half in US32D looks like an error — because it is. Confirming finish consistency across a set during submittal review is a step that prevents a visible problem at installation.
Reading Fire Rating Coordination
If the door schedule shows a fire rating at an opening, every component in the hardware set for that door needs to be compatible with that rating. This means: the lockset or exit device must be fire-rated listed, the closer must be present and rated, the hinges must be fire-rated, and no non-rated components can be substituted.
When reviewing a hardware set for a fire-rated door, the question to ask for every component is: is this product listed for use on a fire-rated assembly? If the schedule doesn't make that clear, confirm it before the order ships.
Common Mistakes Contractors Make
Using the wrong set for the opening. Hardware sets apply to groups of doors, but not every door in a group is identical. If door 112 is in Set 3 but has a note in the door schedule for a special function lockset, that note overrides the standard set for that door. Reading the hardware set without checking the door schedule notes is how exceptions get missed.
Misreading handing from the schedule. Hardware schedules may note handing for items like closers and exit devices that are handed (they differ by swing direction). Misreading the handing designation — particularly confusing "RH" and "RHR" (right hand reverse, for outswinging doors) — results in hardware that's physically the wrong product even though the set number was right.
Ignoring the "by others" notation. Hardware schedules sometimes include items designated "by others" — typically meaning furnished by a separate contractor (the access control contractor, for example) or by the owner. These items should not be duplicated in the door hardware contract. Missing this notation and ordering everything in the set regardless is a coordination error.
Not reconciling schedule revisions. On active projects, hardware schedules go through revisions. If you're working from an earlier version, you may be installing hardware that's been superseded. Always confirm you have the current schedule before pulling product.
Assuming "similar" means "same." If an opening is noted as "similar to Set 3," it means there are differences — otherwise it would just be Set 3. Find out what the differences are before installing.
Overlooking the hardware prep coordination. The hardware set tells you what hardware is going on the door. The door schedule (and the door submittal) needs to confirm that the door and frame arrived with the correct preps for that hardware. If Set 3 calls for a mortise lockset and the door was prepped for cylindrical, you have a coordination failure — and it shows up at installation, not before.
A Note on Submittals
The submittal review process — where the hardware schedule is reviewed and approved before the order is placed — is the most effective quality control step in the entire door and hardware process. It's when spec-to-submittal conflicts get identified, hardware set errors get corrected, and fire rating coordination gets verified. Contractors who engage in the submittal process carefully, and who ask questions when something doesn't look right, catch problems before they're in the wall.
We review submittals as part of how we work with contractors and facility managers across Nebraska. It's not a formality — it's the step that keeps the schedule clean and the installation right.
Closing Out the Series
Over these ten articles, we've covered the full commercial opening from foundation to finish: frames, doors, hinges, locksets, closers, electrified hardware, fire rating requirements, and the documents that tie it all together. The goal was never to turn contractors and facility managers into hardware specifiers — it was to build the working knowledge that makes collaboration more effective, catches problems earlier, and produces openings that work the way they're supposed to.
We've been doing this work across Nebraska for 30+ years, and the projects that go smoothest are the ones where the people in the field understand what they're building and why. That's what this series was about.
If you have questions about any of the topics covered here, or want to talk through a specific project, we're easy to reach.
