For years I've specified a BHMA B04013 Shelf rest as a metal two-pin type with shelf hold-down clip. Checking the internet I cannot find a manufacturer offering these in metal. Plastic, not a problem, but metal nowhere to be found.
Has everyone simply gone to the plastic and does it provide decent service? Our projects do require a fair level of durability.
Thanks.

The applicable BHMA standard is ANSI/BHMA A156.9 "American National Standard for Cabinet Hardware." I'm looking at the 2001 version, and don't know if that is current, but B04013 shelf supports are identified under Section 5.5, "Shelf Rests and Standards" This paragraph requires Test 7 and Test 15.

Test 7 (Section 4.8) is a static load and impact test of a representative section of shelving, using a 100 lbf static load and with a superimposed 20 in-lbf impact load without collapse or failure of the rest. The BHMA A156.9 standard goes into even more excruciating detail about how the test is done, if you are interested further. Test 15 is a finishes test, and probably not of concern.

Your spec is essentially a performance spec, and the BHMA referenced standard is of course a minimum standard. Both plastic and metal comply, but I, like you, feel more comfortable with metal as being better than plastic. I have seen and purchased metal at the big box hardware store for use in my house, within the past year, so I bet they are still available.

By the way, the first numeral in the product designation is the material code, "0" being "optional materials" so the B04013 designation itself allows plastic. You'd want B54013 with "5" for "stainless steel", or similarly "3" for "aluminum - except wrought", "4" for "wrought aluminum" if you want to get specific with material choice.

Another source might be a call to your local woodworkers supply store, or to a cabinet maker you've dealt with. Good luck.

Now there's a guy with time on his hands... Great post, George!

I think the concern that Mr. Hunter has is that while there may be great products out there, they do not claim to perform according to B04013. This does not mean that they would or would not comply, just that they make no claims in this regard.

Writing a performance specification that can't be enforced is the kind of thing that we can get into without realizing it. In this particular case, I would like to see the manufacturers test the performance of their product. I assume that the manufacturer's would claim that it is a waste of their resources to do so since they are already selling enough of the product.

Thanks George for the learning moment this morning.
I appreciate your explanation for the material coding.

Thanks George for the very complete explanation and to everyone else for participating. The seismic clip is an important feature here in the Bay Area, and while the plastic may perform adequately at the initial installation, one wonders how they'll fare after the shelves are moved a time or two.
Clearly have to revise my master.

To some this may seem like a stupid question, but where does one find cabinet hardware products that comply with BHMA standards? For example, when I do an internet search using "BHMA B04013 Shelf rests" as the search term, I can find BHMA documents and specifications that list the standard, but I cannot find any products that indicate compliance with that standard. For years I have specified cabinet hardware using the BHMA standards (because that is what comes with ARCOM's specifications), but I feel lost as to knowing what the products actually look like.

Help!

A lot of cabinet hardware has been tested for compliance with the BHMA standards. The manufacturers don't advertise this because the people who buy the hardware, cabinet makers, generally don't care.

You could enforce your spec by asking for documentation with the shop drawings. You might also need to confirm that the documentation goes with the product actually provided.

Stephen - thanks for your response. The problem is that I prefer to verify what I am specifying it before I specify it! I would like to know exactly what a "BHMA B04013 Shelf rest" or any other hardware component is before I include it in the spec. By the time submittals arrive, it is too late to review alternatives with the project team.

Ed, try to obtain copies of the BHMA standards for your library. They have generic illustrations that show the basic products.

I sent a message to BHMA saying I needed an architectural guide. They had one in the past.

If we all write them, they might get the idea.

Thanks Ron. It appears on BHMA's website that they do sell PDFs and printed copies. I will need to weigh the cost of obtaining these along with the many other publications I should acquire.

Revisiting this topic months later: I don't find a two-pin shelf rest available by search. Can you put me onto a manufacturer?

This just came up on one of my projects. I find a fair number of plastic shelf rests with holddown pins, but no metal ones.
