Door Hardware Sets: What They Are and How Estimators Use Them

Door hardware sets explained

A door hardware set is the grouped list of all the hardware needed for one type of opening, given a number so the door schedule can point to it. Sets are also called hardware groups or headings. They are how a door-and-hardware job stays organized: define the hardware once as a set, then reference that set everywhere the same opening repeats.

What a hardware set is

A hardware set is a complete list of the hardware for one kind of opening, bundled together and numbered. Instead of listing every hinge, lock and closer against every door, the spec defines a set, say Set 03, and then applies Set 03 to every opening that needs that exact hardware.

You will see sets labeled in different ways, such as HW-1, Set 01 or Heading A, but the idea is the same: a numbered package of hardware that one or more openings share.

Why sets exist

Buildings repeat openings. A floor of offices might have twenty doors that all need the same lockset, hinges, closer and stop. Writing that hardware out twenty times would be long and error-prone, and any change would have to be made in twenty places.

A set solves that. Define the hardware once, give it a number, and reference the number against each matching opening. Change the set and every opening that uses it updates together. It keeps the documents short and keeps repeated openings consistent.

What a typical set lists

A set lists each hardware item with a quantity, a description or product number, a finish and often the manufacturer. It is written so a distributor can price and order from it directly.

Quantities for each item (e.g. 3 hinges, 1 closer)
Product numbers or catalog descriptions
Finish codes (such as the BHMA finish for each item)
Manufacturer or approved-equal references
The function of key items (lock function, exit device type)

How set numbers map to openings

The connection runs through the door schedule. Each opening on the schedule carries a hardware set number in its hardware column. That number is the pointer to the set in the hardware schedule.

So the flow is: the door schedule lists opening 112 and assigns it Set 05; the hardware schedule defines Set 05 as a specific list of items. Read together, you know exactly what hardware opening 112 gets. Multiply that across every opening carrying Set 05 and you know how much of that hardware the job needs.

How estimators price from sets

Estimators price a project by pricing each set once and then multiplying it across the openings that call for it. Count how many openings use Set 01, price Set 01, multiply; repeat for every set; add it up, and you have the hardware cost for the job.

This is why clean sets matter so much to a bid. If a set is priced wrong, the error is multiplied by every opening that uses it. If an opening is assigned the wrong set, its hardware is wrong from the start. The set is the unit the whole hardware estimate is built on.

Working sets in a system

Because sets are reused and multiplied, keeping them accurate and consistent is where a lot of estimating time goes, and where spreadsheet errors creep in. eMullion lets a distributor build hardware sets once and reuse them across openings and projects, so a priced set stays the same set when it is ordered and submitted.

Frequently asked questions

What is a door hardware set?

It is the grouped, numbered list of all the hardware needed for one type of opening. The door schedule references the set by number, so every opening that needs the same hardware points to the same set.

Why are hardware sets used?

Because buildings repeat openings. Defining the hardware once as a numbered set and referencing it keeps documents short, keeps repeated openings consistent, and lets a change update every opening that uses the set at once.

How do hardware sets map to the door schedule?

Each opening on the door schedule carries a hardware set number. That number points to the set's full item list in the hardware schedule, so reading the two together tells you exactly what hardware each opening gets.

How do estimators price a project from sets?

They price each set once, then multiply it across the openings that call for it. A wrong set price or a wrong set assignment is multiplied across every opening that uses it, which is why clean sets matter.
