Glass clamps

About Glass Clamps

A glass clamp is a stainless-steel bracket that grips a glass panel along its edge using clamping pressure and rubber inserts, securing the panel to a post, wall or flat structure without requiring a drilled hole in the glass.

Two halves tighten around the panel edge, with interchangeable rubber inserts that cushion the contact and accommodate different glass thicknesses.

Strofix supplies glass clamps in a wide range of body sizes — from 30×30 mm mini clamps to 55×67 mm large-body variants — for flat-surface and round-pipe mounting (Ø42.4 and Ø48.3 mm), in AISI 304 or AISI 316 stainless steel with satin or polished finishes.

The category also includes specialty clamps (90° corner, 180° inline, lateral fixing, middle and ending positions), replacement rubbers for glass thicknesses from 4 to 21.52 mm, front handles, glass clamp connectors and glass support plates.

The correct clamp depends on mounting surface, body size, glass thickness and the position within the railing run.

How to choose a glass clamp

1. Mounting surface: flat or round pipe

This is the first decision. Flat-back clamps mount to walls, floors, square posts and flat-sided railing posts.

Pipe-mount clamps have a curved saddle profiled for Ø42.4 or Ø48.3 mm round tube.

The back profile must match the mounting surface — a flat clamp will not sit securely on a round pipe and vice versa.

2. Body size and overhang

Body size determines how much glass edge the clamp grips and how visually prominent the bracket is.

Compact clamps (30×30 mm, 40×50 mm, 45×45 mm) suit lightweight panels and decorative infills.

Larger bodies (52×52 mm, 55×67 mm, 45×63 mm) provide a wider clamping area with more glass-edge overhang for heavier panels and balustrade applications where hold strength is critical.

3. Position in the railing run: middle, ending, corner or inline

Strofix offers position-specific clamp variants.

Middle clamps sit between two adjacent glass panels, ending clamps terminate the run, 90° clamps join panels at a corner, and 180° clamps join two panels in a straight line.

Standard clamps are used at intermediate post positions.

Identify all positions in the railing layout before ordering.

4. Glass thickness (4–21.52 mm)

Each clamp is supplied with interchangeable rubber inserts for a specific glass thickness.

Standard rubbers cover single-pane thicknesses of 4, 6, 8, 10 and 12 mm.

Laminated-glass rubbers are available for 8.76, 10.76, 12.76, 13.52, 16.76, 17.52 and 21.52 mm build-ups.

Clamps can also be ordered without rubbers for non-standard thicknesses.

Replacement rubbers are sold separately in the Rubbers for glass clamps subcategory.

5. Steel grade and finish

AISI 304 is the standard grade for interior and typical exterior installations.

AISI 316 is available on selected variants for coastal, pool and high-humidity environments.

Satin finish is the default across the range; polished is available on selected compact variants for a brighter, reflective appearance.
