Glass Clamp - 4PCS Glass Bracket for 1/3"-1/2" Tempered Glass, Stainless Steel 304 Flat Back Square Glass Clip Polished for Balustrade 、Staircase 、Handrail, Glass Holder Metal Casting

Great value, looks perfect

At about 1/4 the price of the US brand, these are both affordable and very nice. Although I used all of mine to hold glass well away from its corners, these come with a corner close-out which can be placed on either end of the clamp, allowing them to hold glass on a slope. They also come with a rubber-ringed dowel, if you are going to dowel your glass in place, rather than just clamp it. The rubber clamping pads included come in two thicknesses, which means that these clamps seem to be able to clamp glass from a bit thinker than 3/8" to 1/2" thickness. I do NOT believe they will properly clamp 3/8" glass, though.The only negative here is that the small bearing pads (2 per clamp) that the glass is supposed to sit on are factory-glued in place with a poor glue that does NOT hold up well. Several of these bearing pads were detached in the box, and a few were lost, not in the box. My solution to that was to buy a roll of 1/16" neoprene mat, cut out 120 new ~3/8" x 3/8" bearing pads, and use some Pliobond to glue them in place of the OEM bearing pads. PITA, but these clamps are otherwise very satisfactory.The clamps get mounted to floor and posts via 5/16" max dia screws or bolts. I bought some hex-drive cap screws to mount the clamps to steel (drilled and threaded for the screws), and used some metal roofing screws to hold the clamps to the wood floor (pilot drilled). YMMV.I guess I should add that I'm using these indoors, so far. They are made of 304 stainless, which isn't quite as corrosion resistant as 316 stainless, though still good. I bought an extra one, and will set it outside for a couple of months before committing to using it on an exterior deck.

Installed these clamps to hold up a 1/2" thick tempered glass sneezeguard on solid surface counters in an ice-cream shop. I used 5 clamps to hold up 1/2" thick x 18" high x 105" glass sneezeguard. The clamps come with several sized rubber inserts for the different thickness of glass. The finish is not top quality as say CRL but you can't really tell. Plus you cant beat the price less than half the price. The clamps are beefy and would definitely hold larger panes of glass as long as you have an adequate amount of clamps. For added security I used LOCK-TIGHT 263 (blue) on the bolts.
