Where do you typically specify all the connectors sometimes used for hanging glass shelves or glass display panels attached to walls (the type provided by companies like C.R. Lawrence)?
They dont seem significant enough to warrant their own spec section, but it doesnt seem intuitive to put them in the Glazing spec with glass or in the Interior Architectural Woodwork spec with wood shelving and its hardware. (Ive done the latter in the past).
We have specified products like this on the Drawings in the past, and/or on the Architectural Interior Product Pages, which are an Apendix in the Project Manual. We then reference that appendix in the appropriate spec sections, whether it be all glass, or part of a casework element. In one recent project, we did a wine room for a restaurant completely out of glass and cable support systems. We specified the laminated glass in the Glazing Section and referenced the Architectural Interiors Product Pages for the minute details.
It seems that in the MF04 arena, it would most likely be a candidate for Section 10 12 00 Display cases, as its own section, which is probably what I will do as we move forward with updating our Office Masters to MF04.
When it’s part of casework, I put them in with architectural woodwork. If they were ‘stand alone,’ I’d probably put them with glazing. May not be intuitive, but the glaziers will supply the glass and have access to the suppliers of these parts, so I would think it would work OK.
If there is any related true casework, with sort of similar glass shelves within casework assemblies, I would jump on the chance to lump it all together in the “Casework” Spec.
Otherwise I put it in the “Interior Glazing” spec. My rational there is that we include other metal trims and accessories like J-molds in the “Interior Glazing” spec, so these are merely more elaborate metal accessories.
On the other hand, if the project has numerous small decorative metal bits poping up everywhere for a variety of purposes that are hard to place and do not each warrant a Section of their own, I would put them all in a “Interior Ornamental Metal” Spec.
The spec writer I learned from would always include a “Section 10990 - Miscellaneous Interior Specialties” in every project that served as a dumping ground for every little thing like this where working it out might have delayed lunch.
The worse thing I think is to create a unique custom spec for a little piece of work where the entire scope might fit in the trunk of the sales reps rental car.
Since I generally put all of the casework in the Architectural Woodwork section, that is where I spec the casework hardware as well. A lot of it is installed by the casework manufacturer anyway.

Mostly, it depends on the type of project and the extent and type of shelving. If it’s a place where there are other display materials (i.e. a hospital gift shop with slatwall, too), then it makes sense to me to lump all that in one section. If it’s one or two shelves, then the glass is in Glazing and the fittings are in Architectural Woodwork (or if there’s no woodwork, in Interior Finish Carpentry) with references to the other section.
I actually put them with the casework with a reference to the glazing section. Think of them as a “shelving system” only that the shelves are glass. I’ve done a lot of high end display situations, and that casework section can get pretty far-flung, but its typically those guys bidding on it, not the glaziers. (its not unusual to have some glass in casework – like a display case – and I think the casework suppliers are more used to working with the fine degree of detail needed for this installation.
