Glass clamp 52x52mm, Satin, 42.4, With support

The Strofix glass clamp 52×52 mm for Ø42.4 tube with support is a stainless-steel glass panel holder designed for mounting on Ø42.4 mm round railing post tubes. The clamp measures 52 × 52 × 32 mm (L × H × depth) and holds glass panels from 8 to 12.76 mm thick. The distance between the mounting surface and the glass panel is 16 mm. Available in AISI 304 or AISI 316 with a satin finish. Includes security plate and safety pin. Attached by screwing.

The 52 × 52 mm is a large square tube-mount glass clamp for the Ø42.4 pipe; only the 55 × 55 mm is larger. The 32 mm depth and the 8–12.76 mm glass range make this a heavy-duty clamp for thicker glass on round tube post systems – it does not accommodate glass below 8 mm. The 16 mm standoff keeps the glass closer to the tube surface than the 20 mm standoff on the 45 × 45 tube clamps. Glass thickness options include 8, 10, and 12 mm single tempered glass and 8.76, 10.76, and 12.76 mm laminated safety glass (12.76 mm = 66.2 designation). The included security plate and safety pin provide secondary glass retention and enable side-mounting to posts. 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:

• Heavy-duty glass clamping on Ø42.4 mm round tube posts for 8–12.76 mm glass
• Thicker glass balustrade panels on round tube railing systems
• Commercial glass railings on round posts that need a larger clamp body
• Side-mounting thick glass panels to round posts with the included security plate
• Coastal installations requiring AISI 316 for heavy glass on round tube posts

FAQ

What glass thicknesses are supported?

The clamp accepts glass from 8 to 12.76 mm: single tempered glass (8, 10, 12 mm) and laminated safety glass (8.76, 10.76, 12.76 mm / 44.2, 55.2, 66.2). Glass below 8 mm is not supported – for thinner glass on Ø42.4 tube, use the 45 × 45 tube clamp.

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

The 45 × 45 handles 4/6–10.76 mm glass with a 20 mm standoff. This 52 × 52 extends to 12.76 mm (including 12 mm tempered and 66.2 laminated) with a 16 mm standoff and deeper 32 mm body. Choose the 52 × 52 when the glass is thicker than 10.76 mm.

What is the standoff distance?

The standoff is 16 mm – the distance from the tube surface to the glass panel. This is 4 mm shorter than the 20 mm standoff on the 45 × 45 tube clamp, positioning the glass closer to the post.

How does this compare to the flat-mount 52×52?

Both are 52 × 52 × 32 mm with the same 8–12.76 mm glass range and AISI 304/316 options. The difference is mounting surface: this product has a curved back for Ø42.4 round tubes with a 16 mm standoff; the flat version has a flat back with a 20 mm standoff.

Does this include support?

Yes. The clamp includes a security plate and safety pin for secondary glass retention and side-mounting capability.

Which steel grades are available?

AISI 304 and AISI 316. Choose AISI 316 near the sea, around outdoor pools or where de-icing salt is used.

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 seven body sizes – from the compact 30 × 30 mm mini clamp through 40 × 50, 45 × 45 and 45 × 63 mm to the larger 52 × 52, 55 × 55 and 55 × 65 mm bodies – all profiled for Ø42.4 mm round tube, in AISI 304 or AISI 316 stainless steel with satin or polished finishes.

Clamps marked "With support" have a security plate and safety pin under the glass edge; the others hold the glass by clamping pressure alone. The correct clamp depends on glass thickness, body size, steel grade and whether a support is needed.
