The Square Glass Standoff 50 × 50 mm, Single, for 8–17.52 mm Glass (MOD 2921) is a square glass standoff: a 50 × 50 mm stainless steel block with a clamp plate and rubber inserts that grip the glass. It suits modern projects with square posts and flat details.

Installation notes
- Drill the glass with the hole size shown in the catalogue for this model, and always use tempered or laminated safety glass.
- Fix the standoff with an anchor that suits the base: chemical anchor in concrete, through-bolt in steel, or the matching screw in timber.
- Keep the rubber or PVC washers between the glass and the metal; steel must never touch the glass directly.
- The number of standoffs per panel and the edge distances depend on the glass size and the load – ask an engineer for public or commercial projects.
