Glass clamp 40x50mm, Polished, 42.4

The Strofix glass clamp 40×50 mm polished 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 mirror-polished finish. Attached by screwing.

The polished finish provides a high-gloss, mirror-like appearance on the round tube post. This product is notable in the Strofix glass clamp range as one of the few polished clamps available in both AISI 304 and AISI 316 — most polished variants are limited to AISI 304 only. This makes it suitable for premium coastal installations where both a polished aesthetic and marine-grade corrosion resistance are required. The rectangular 50 × 40 mm body provides a wider-than-tall profile on the post. 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).

Use cases:

• Polished glass clamp on Ø42.4 mm round posts with AISI 304 or AISI 316 grade options
• Premium coastal installations requiring both polished finish and AISI 316 marine grade
• Mirror-finish rectangular tube-mount clamp for contemporary railing designs
• High-end glass railing projects on round tube posts where polished 316 is specified
• Alternative to the square 45 × 45 polished tube clamp with rectangular body proportions

FAQ

Is AISI 316 available with polished finish?

Yes. This is one of the few polished glass clamps in the Strofix range available in both AISI 304 and AISI 316. Most other polished clamp variants are limited to AISI 304 only, making this product particularly suitable for coastal or high-humidity installations requiring polished hardware.

How does this compare to the satin 40×50 tube clamp?

Both share the same 50 × 40 × 26 mm body, Ø42.4 tube mounting, AISI 304/316 grade options, and 6–10.76 mm glass range. The difference is surface finish (polished vs satin) and price. The satin version includes support; check whether this polished version also includes support.

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.

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

Both are polished tube-mount clamps for Ø42.4 with 20 mm standoff. The 40 × 50 is rectangular and offers AISI 304/316; the 45 × 45 polished is square and AISI 304 only. Choose the 40 × 50 for rectangular proportions or when AISI 316 polished is required.

Does the polished finish require special maintenance?

Polished stainless steel shows fingerprints more readily than satin. Regular cleaning with a stainless-steel cleaner maintains the mirror appearance.

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.
