What shows up in glazing hardware
- Spider fittings and routels from point-supported glass work
- Patch fittings, top and bottom, for all-glass entrances
- Glass clamps, brackets, and standoffs from railing and partition jobs
- Door rails, pivots, and floor closers
- Shower and partition hinges and hardware sets
Before you buy
Surplus is only a bargain if it fits and it's documented. These are the questions worth asking on this category specifically.
- Fittings are made for specific glass thicknesses — a 1/2" clamp will not hold 3/8" glass safely, gasket shims notwithstanding
- Hole patterns must match the prep already in your glass; the fitting will not move and neither will the hole
- Confirm load rating for anything structural, especially railing hardware and point supports
- Match finishes across a run; brushed stainless from different suppliers rarely matches exactly
- Ask for gaskets, bushings, and setscrews — missing small parts are what make cheap hardware expensive
- For railing hardware, confirm what code path it was tested under and whether documentation exists
Common questions
Can I use a glass clamp rated for a different thickness?
No. The clamp's gasket and jaw geometry are sized for a specific glass thickness, and shimming to fit compromises the grip and the load path. Match the hardware to the actual glass thickness.
Does surplus railing hardware need documentation?
For structural glass railing, yes. Guards are load-rated assemblies, and inspectors may ask what system the hardware belongs to and how it was tested. Hardware with no traceable system is difficult to use on permitted work.
