Glass clamp 40x50mm, Satin, 42.4

The Strofix glass clamp 40×50 mm for Ø42.4 tube is a stainless-steel glass panel holder designed for mounting on Ø42.4 mm round railing post tubes. The clamp measures 50 × 40 × 26 mm (L × H × depth) and holds glass panels from 6 to 10.76 mm thick. The distance between the mounting surface and the glass panel is 20 mm. Available in AISI 304 or AISI 316 with a satin finish. Includes support. Attached by screwing.

The rectangular 50 × 40 mm body provides a wider-than-tall profile on the round post tube, which may be preferred aesthetically for certain railing configurations compared to the square 45 × 45 clamp. The curved back face wraps around the Ø42.4 mm tube surface. Glass thickness options cover single tempered glass (6, 8, 10 mm) and laminated safety glass (8.76, 10.76 mm). This is the tube-mount equivalent of the flat-mount 40 × 50 clamp, sharing the same body dimensions but with a curved back for round tube installations. AISI 304 is suitable for standard installations; AISI 316 provides higher chloride resistance for coastal or exposed environments.

Select the glass thickness and steel grade in the dropdowns at order time.

Use cases:

• Rectangular glass clamp profile on Ø42.4 mm round railing post tubes
• Glass balustrade panels on round tube post systems with a wider-than-tall clamp body
• Standard glass thickness range (6–10.76 mm) on round tube railing installations
• Alternative to the square 45 × 45 tube clamp when a rectangular profile is preferred
• Coastal installations requiring AISI 316 tube-mount glass clamps

FAQ

How does this compare to the 45×45 tube clamp?

Both mount on Ø42.4 tube with AISI 304/316 satin and a 20 mm standoff. The 40 × 50 is rectangular (wider than tall); the 45 × 45 is square. The 45 × 45 without support also accepts 4 mm glass; this 40 × 50 starts at 6 mm. Choose based on the desired visual proportion on the post.

What glass thicknesses are supported?

The clamp accepts glass from 6 to 10.76 mm: single tempered glass (6, 8, 10 mm) and laminated safety glass (8.76, 10.76 mm).

What tube does this clamp mount on?

The clamp mounts on the Ø42.4 mm round railing post tube with a curved back face.

Does this include support?

Yes. The description indicates this clamp includes support.

Which steel grades are available?

AISI 304 and AISI 316. Choose AISI 316 for coastal, pool, or high-humidity installations.

How does this compare to the flat-mount 40×50?

Both share the 50 × 40 × 26 mm body and the same glass range. The difference is the mounting surface: this product has a curved back for Ø42.4 round tubes; the flat version has a flat back for walls and square posts. Both have a 20 mm standoff.

About Glass Clamps for Pipe

A glass clamp for pipe is a stainless-steel bracket with a curved back profiled to sit flush against a round post, gripping a glass panel along its edge without requiring a drilled hole. The curved saddle wraps around the tube circumference, and the front half clamps the glass with rubber inserts that cushion the contact and accommodate the panel thickness.

Strofix supplies pipe-mount glass clamps in eight body variants — from compact 45×45 mm and 40×50 mm bodies to larger 52×52 mm, 55×67 mm and 45×63 mm bodies with glass-edge overhangs up to 18 mm — profiled for Ø42.4 mm and Ø48.3 mm round pipe, in AISI 304 or AISI 316 stainless steel with satin or polished finishes.

Most variants include an integrated glass support shelf; one compact variant is supplied without a supporter. The correct clamp depends on body size, pipe diameter, steel grade and whether a built-in glass support is needed.
