Glass clamp 55x55mm, Satin, 42.4, With support

The Strofix glass clamp 55×55 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 55 × 55 mm and holds glass panels from 8 to 12.76 mm thick. Available in AISI 304 or AISI 316 with a satin finish. Includes security plate and safety pin. Attached by screwing.

The 55 × 55 mm body provides a larger visual profile on the Ø42.4 post tube than the 52 × 52 mm clamp while covering the same glass thickness range (8–12.76 mm). The slightly larger face may be preferred for visual proportion on wider railing post configurations or where a more prominent clamp presence is desired. 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:

• Larger-profile glass clamping on Ø42.4 mm round tube posts for 8–12.76 mm glass
• Visually proportionate clamp for wider railing post configurations
• Thick glass balustrade panels on round tube post systems with prominent clamp presence
• Side-mounting thick glass panels to round posts with the included security plate
• Coastal installations requiring AISI 316 for heavy glass on Ø42.4 posts

FAQ

How does this compare to the 52×52 tube clamp?

Both handle the same 8–12.76 mm glass range on the Ø42.4 tube with AISI 304/316, satin, and included support. The difference is the face size: 55 × 55 mm versus 52 × 52 mm. The 55 × 55 provides a slightly larger and more visually prominent clamp on the post. Choose based on the desired visual proportion.

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.

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 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.

How is the clamp attached?

The clamp is attached by screwing.

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.
