FAQ

What makes this the top-specification variant?

This clamp combines the polished mirror finish (aesthetic premium) with the security plate and safety pin (safety premium) on the Ø42.4 tube mount. The other 45 × 45 tube variants offer either satin finish, no support, or both.

How does the pricing compare across the 45×45 tube Ø42.4 family?

The family is priced progressively: satin without support (€5.05) is the base, satin with support (€5.92) and polished without support (€6.15) are mid-range, and this polished with support (€6.99) is the highest.

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).

Is AISI 316 available?

No. This polished with-support variant is AISI 304 only. For AISI 316, use the satin with-support version (SKU ST-445450B-4S).

What tube does this clamp mount on?

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

Can this be side-mounted to posts?

Yes. The included security plate enables side-mounting to posts.

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.
