Exactly what is "builders hardware"?

Builders hardware -- sometimes referred to as architectural hardware, building hardware or finish hardware -- consists of products that are mounted onto the moving parts of buildings (doors, windows, drawers, etc.) in order to move, fasten or protect them. Examples of builders hardware include locks, latches, cabinet hardware, hinges, door hardware, door closers, exit devices, power doors, sliding doors and folding doors.

How can I determine the grade of a particular builders hardware product?

Many builders hardware items are available as Grade 1, 2 or 3 (Grade 1 is the highest).

The grade of a particular hardware item can be ascertained by looking at its BHMA product number.

Grading criteria are product-specific, and are set forth in the applicable ANSI/BHMA standard(s) covering that product.

What are different grades?
How does the BHMA product numbering system work?

Every BHMA product can be identified by a five digit identification number preceded by a prefix letter. (The illustration which follows is purely an example. Products are different by nature, therefore product categories each have numbering systems that may be slightly different. You must refer to the actual standard.)

For example, a product number for a cabinet hardware item might be listed as B 5 2 1 3 1

The prefix letter denotes the BHMA Product Section that produces the hardware.

The first numeral designates the base material for the product. BHMA standards use the default number '0' to allow the manufacturer to use an optional material that meets the performance requirements of the applicable standard.

The second number identifies the type of product.

The third and fourth numerals identify the function of the specific item.

The fifth number indicates the performance grade or other descriptions of the product. See applicable standard.

Every ANSI/BHMA standard contains an explanation of the BHMA product numbering code applicable for that particular category of hardware. Using the example above, a specifier would refer to the ANSI/BHMA Standard A 156.9 for cabinet hardware, and ascertain that for product B 5 2 1 3 1...

B = Product Section for cabinet hardware hinges

5 = Stainless steel

2 = Cabinet knob

13 = Back mounted

1 = Grade One

Thus the product is a Grade 1, back-mounted stainless steel cabinet knob.

How often are BHMA standards updated?

The American National Standards Institute (ANSI) requires the standards to be updated every five years, although many BHMA standards are updated more frequently. The revision date for a standard is often shown as a two-digit numerical suffix to the standard number. For example, A156.10-99 means that ANSI/BHMA Standard A156.10 was last reviewed in 1999.

Is BHMA-sponsored certification restricted to products manufactured by BHMA members?


Any manufacturer may submit an applicable hardware item for certification.
