Description
This stand-off fixes a frameless glass panel to the face of a stair stringer, mezzanine fascia, balcony slab edge or wall, holding the glass on a deep 50mm body with a neat round stainless cap on the front. It is grade 316 (marine grade) stainless steel with a satin brushed finish, 50mm across, for drilled glass 8mm to 22mm thick, including 17.52mm and 21.52mm laminated guarding glass. A threaded sleeve fixes to the structure and screws into the back of the body for fine adjustment, an M10 bolt passes through the glass, and rubber gaskets sit either side so the glass never touches metal. The deepest stand-off in the range, it leaves room behind the glass for cladding, a fascia or a stair nosing. The price shown is for one stand-off.
What you get
| Sold as | One stand-off |
|---|---|
| In the box | Body, threaded adjusting sleeve, cap with M10 bolt, one flat rubber gasket and one sleeved rubber gasket |
| Material | Grade 316 stainless steel, satin brushed |
| Not included | The glass, and the bolt or anchor that fixes the sleeve to the structure |
Why choose this stand-off
The deepest in the range. The 50mm body holds the glass further off the fixing face than the 30mm and 40mm stand-offs, so the glass clears timber cladding, a deep fascia, a stair nosing or render without packing.
Takes thick laminated glass. Glass from 8mm up to 22mm thick fits between the cap and the body, which covers 17.52mm and 21.52mm laminated guarding glass.
Grade 316 for outdoor and coastal work. 316 stainless contains molybdenum, which resists the chlorides in sea air, pool water and de-icing salt far better than 304, so it suits balconies and terraces as well as indoor stairs and mezzanines.
Adjustable to get the glass true. Stringers and slab edges are rarely flat. The threaded sleeve screws in or out of the body, so each stand-off can be set until the glass runs straight and plumb along the whole run.
Rubber both sides of the glass. A flat gasket behind the glass and a sleeved gasket in the hole and under the cap spread the clamping load and protect the edge of the hole.

How many do you need?
Side-fixed balustrade panels are usually held by four stand-offs, two near each vertical edge, and wider or taller panels may need six. The number, spacing and glass specification for a guarding balustrade should come from your glass supplier or structural designer, because the stand-offs carry all the load on the glass.
Fitting
Fix the stand-off positions first and send the hole centres to your glass supplier, because the glass must be drilled before toughening. The sleeved gasket that lines each hole has a 24mm collar; confirm the hole size with your glass supplier. Fix each sleeve to the stringer or slab edge with a suitable stainless bolt or anchor through its slotted hole, screw the bodies on and set them so the faces line up. Fit the flat gaskets, hang the glass, fit the sleeved gaskets and caps, and tighten the M10 bolts evenly. Do not overtighten on laminated glass.
Care
Wipe with warm soapy water and a soft cloth, and rinse with fresh water near the sea or a pool. Do not use wire wool or chloride cleaners, which can mark the satin finish.
Frequently asked questions
Is the price for one stand-off?
Yes. The price is for one complete stand-off with its sleeve, gaskets, cap and bolt. Most panels need four.
Does the glass need holes?
Yes. The bolt passes through the glass, so each panel needs a hole at every stand-off, drilled before toughening.
Is the fixing into the stringer included?
No. The right fixing depends on timber, steel or concrete, so choose a stainless bolt or anchor to suit your structure.
Why choose 50mm deep rather than 40mm?
Choose 50mm when there is cladding, a deep fascia or a nosing behind the glass, or when you want a stronger floating look. Both take glass up to 22mm.
Can I use it outdoors?
Yes. Grade 316 suits balconies, terraces and coastal sites. Rinse with fresh water now and then to keep the satin finish bright.
