			BHMA Product Numbering Every ANSI/BHMA standard contains an explanation of the BHMA product numbering code applicable for that particular category of hardware. BHMA product numbers utilize a five-digit number preceded by a prefix letter: B52131 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 of the product.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 OneThus the product is a Grade 1, back-mounted stainless steel cabinet knob. Note: Explanations of the number codes applicable to this category of hardware (e.g., 13 = back mounted) would be found in the 156.9 ANSI/BHMA standard. Building hardware products should always be specified by BHMA product number to eliminate any confusion over brand names, performance standards or product grade. As always, we recommend you contact one of the door & hardware specialists at Colorado Doorways with any questions you might have.
