Description
This square clamp holds a glass panel to the flat face of a square post, box section or wall, with no channel, no drilling of the glass and no visible fixings on the glass face. It is grade 304 stainless steel with a satin brushed finish, the standard grade for indoor balustrades, 45 x 45 x 27mm, and comes with rubber pads for 8mm and 10mm glass. Two countersunk screws close the two halves round the glass edge. The price shown is for one clamp, with a minimum order of 8, enough for two panels.
Why use this clamp
Grade 304 for indoor rails. 304 stainless keeps its satin finish indefinitely in dry, heated buildings, and costs less than 316. Use it for stairs, landings, galleries and mezzanines inside homes, offices, shops and schools. Outdoors, near the sea or round a pool, choose the 316 version instead.
Flat back for square posts and walls. Square and rectangular posts, box section, flat bar and walls need a flat-back clamp. It sits flush with no rocking, so the glass lines up straight from post to post. A curved-back clamp would rock on a flat face.
Rubber all round the glass. Glass never touches metal. The pads spread the load along the edge and take up small differences in glass thickness, which protects toughened glass from point loads at the clamp.
Small and neat. At 45mm square it is one of the smallest clamps we sell, so the rail looks light and the glass does the talking.
Where it is used
Indoor glass balustrades with square or rectangular posts on stairs, landings, galleries and mezzanine edges; glass screens fixed to walls and box-section frames; and glass guards and screens in homes, offices, shops, hotels and schools.

How many do you need?
Most panels are held by four clamps, two on each post, set about 150 to 200mm in from the top and bottom of the glass. A run of three panels between four posts takes 12. A tall or wide panel may need a third clamp each side; follow your glass supplier's or designer's layout.
Choosing the right option
Use this flat-back clamp on any face at least 45mm wide. Check the glass is 8mm or 10mm; for 12mm glass use the 304 D clamp 63 x 45mm with a flat back. For round posts choose the clamp curved for 42.4mm or 48.3mm tube. Pick this 304 clamp for dry indoor work, and 316 for anything outdoors, near the sea or round a pool.
Fitting and care
Mark the clamp heights on every post with a level line so the glass sits straight. Drill each post for the fixing, fit the back half, then place the rubber pads for your glass thickness. Set the glass on packers, offer up the front half and tighten the two countersunk screws evenly until the glass is gripped firmly, without overtightening. Use toughened safety glass only. Wipe the clamps with warm soapy water and a soft cloth to keep the satin finish bright. Do not use wire wool or chloride cleaners.
Frequently asked questions
Is the price for one clamp?
Yes. The price is for one complete clamp with both halves, two screws and the rubber pads. The minimum order is 8, which holds two panels.
Does it need a hole in the glass?
No. This clamp grips the glass edge between rubber pads. There is no safety pin, so the glass needs no hole.
Can I use it on 12mm glass?
No, it takes 8mm or 10mm glass. For 12mm glass on a flat post use the 304 D clamp 63 x 45mm with a flat back.
Is the screw that fixes it to the post included?
No. The clamp comes with its two closing screws. The post fixing depends on your post or wall: choose stainless screws and plugs or anchors to suit.
Will it fit a round post?
No. The back is flat. For round posts use the 304 square clamp curved for 42.4mm or 48.3mm tube.
Can I use it outdoors?
We recommend 304 for indoor use. Outdoors, and especially near the sea or a pool, use the 316 square clamp with a flat back, which resists tea staining far better.
