Glass clamp 45x45mm, Flat, Polished, With support

The Strofix glass clamp 45×45 mm flat polished with support is a stainless-steel glass panel holder designed for mounting on flat surfaces such as walls, square posts, and flat-sided structural members. The clamp measures 45 × 45 × 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. Manufactured from AISI 304 with a mirror-polished finish. Attached by screwing.

The "with support" version includes a security plate and safety pin — a metal bracket underneath the glass panel that provides a secondary mechanical safety catch in addition to the rubber gasket clamping force. The polished finish provides a high-gloss, mirror-like appearance for premium installations where both the safety support and a polished aesthetic are required. This is the top-specification variant in the 45 × 45 mm flat clamp family, combining the polished finish with the safety support feature. Glass thickness options cover single tempered glass (6, 8, 10 mm) and laminated safety glass (8.76, 10.76 mm). This product is available in AISI 304 only.

• Interior glass balustrades where polished hardware with safety retention is specified
• Design-led projects combining maximum aesthetics with maximum safety

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). The other 45 × 45 mm flat variants offer either satin finish, no support, or both — this variant provides both upgrades in one product.

What does "with support" include?

A security plate and safety pin sit underneath the glass panel, providing a secondary mechanical catch that prevents the glass from dropping if the primary clamping force is disrupted.

Is AISI 316 available on this variant?

No. This polished with-support variant is available in AISI 304 only. For coastal installations requiring both AISI 316 and polished finish, check availability with Strofix directly.

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).

How does the pricing compare across the 45×45 flat family?

The 45 × 45 mm flat clamp family is priced progressively: satin without support is the base, satin with support and polished without support are mid-range (same price), and this polished with support is the highest-priced variant.

How is the clamp attached?

The clamp is attached to the mounting surface by screwing.

About Glass Clamps for Flat Surfaces

A glass clamp for a flat surface is a stainless-steel bracket that grips a glass panel along its edge without requiring a drilled hole, fixing the panel to a wall, post or flat-sided structure by clamping pressure alone. Two halves tighten around the glass with rubber inserts that cushion the contact and accommodate different panel thicknesses.

Strofix supplies flat-mount glass clamps in ten body variants — from a compact 30×30 mm mini clamp to larger bodies with lengths up to 67 mm, heights up to 45 mm and glass-edge overhangs up to 18 mm — in AISI 304 or AISI 316 stainless steel with satin or polished finishes. Rubber inserts are available for 4, 6 and 8 mm glass, or the clamps can be ordered without rubbers for custom applications.

The correct clamp depends on body size, glass thickness, steel grade and the required finish.
