Adjustable Square Glass to Glass Railing Clamp Stainless Steel Corner Glass Stiffener for Frameless Glass Fence

It is sized for tempered and laminated glass from 8 to 12 mm. The jaw opening is cut for that range, so a 10 mm panel sits tight without shims. If your project uses 6 mm or 15 mm glass, give us the exact thickness when ordering — we will either match the jaw or point you to the right clamp body.

Both versions exist. The fixed version locks at a true 90°, which suits square corners and standard returns on a glass fence. The adjustable version lets you set the included angle in the field, so it handles stair runs and curved balcony layouts where panels meet at something other than a right angle. Specify fixed or adjustable when you order.

It is a corner stiffener: it ties two glass-to-glass panels into one rigid unit and spreads the load across the joint, but it is not the primary support. Keep the panels in base shoe or spigots sized to your local railing code, then add this clamp to hold the corner square and stiffen the run.

No. The two stainless plates sandwich the corner edges and are drawn together with through-bolts; tightening compresses the plates onto the glass. Because nothing is cut into the pane, tempered glass stays fully heat-treated, and the clamp can be repositioned or removed without scrapping the panel.

ss304 suits indoor railings, covered balconies, and most residential jobs. ss316 adds molybdenum for chloride resistance, so use it where the fence faces salt spray: coastal terraces, pool areas, marinas. Geometry and finish options are the same either way; 316 carries a small price premium.

Brushed nickel, chrome, matte black, and custom colors. The nickel and matte black options are PVD finishes, so they hold up to fingerprints and UV better than painted parts. For custom colors, send a RAL number or a physical sample and we will match the rest of your railing hardware.
