Assembly Instructions

The type of the screw needed will vary depending on the type of surface you’re fixing the glass clamp to (e.g. stainless steel post, wall, floor…). The Hexagon Socket Head Cap Screw (M8), shown below, is the standard screw to be used when fixing the glass clamps to steel posts. You may want to choose the correct fixing screw with similar dimension as this.

Below is a typical glass clamp application, displaying the recommended positions for fixing the glass clamps. However, some customers prefer fixing the clamps on top and bottom.

 Dimensions (mm)  Min.  Max.
 W  Width of Glass  500  1200*
 H  Height of Glass  800  1000*
 h1  Distance between handrail and top of the glass  10  50 without edge protection, 100 with edge protection
 h2  Distance between floor and bottom of the glass  10  50 without edge protection, 100 with edge protection
 h3  Glass edge above – axle upper glass clamp  100  150
 h4  Glass edge below – axle lower glass clamp  100  150


*Max. Size depends on glass type, thickness, and wind factor (when using outdoor).
** For safety reason, we suggest using the Secure Pin (supplied with your clamps) when the glass panel is fixed to the outside of a staircase and is overhanging.

* Zinc Alloy and SUS304 grade Stainless Steel suits internal use; With increased corrosion resistance, the SUS316 grade Stainless Steel can be used for both interior and exterior and is better suited for coastal or more heavily polluted environments.

** For safety reason, we suggest the Secure Pin (sold separately) to be used when the glass panel is fixed to the outside of a staircase and overhanging.

    I’ve just replaced my wooden staircase balustrades with toughened glass. I used Express Toughening to supply the 10mm thick glass panels. The company is very professional and helpful. The project went well.
