Glass clamp 60x70mm, Flat, Satin, With support

The Strofix glass clamp 60×70 mm flat with support is the largest and heaviest-duty glass clamp in the Strofix range, designed for the thickest laminated safety glass panels available — 17.52 and 21.52 mm. The clamp mounts on flat surfaces such as walls, square posts, and flat-sided structural members. The distance between the mounting surface and the glass panel is 20 mm. Manufactured exclusively from AISI 316 stainless steel with a satin finish. Includes support. Attached by screwing (elements for screwing included).

This is the only glass clamp in the Strofix range manufactured in AISI 316 as the sole grade option — reflecting the fact that installations requiring glass this thick are typically high-specification commercial or public-access projects where marine-grade corrosion resistance is standard. The 17.52 mm glass option covers heavy laminated safety glass configurations (e.g., two tempered panes with PVB interlayer), while the 21.52 mm option is the absolute maximum glass thickness in the Strofix product line, covering the heaviest structural laminated glass balustrade panels specified for extreme wind loads, crowd barriers, and high-security applications.

Select the glass thickness in the dropdown at order time. A "without rubbers" option is available for ordering the clamp body only.

Use cases:

• Ultra-heavy laminated glass balustrade panels at 17.52 or 21.52 mm thickness
• High-specification commercial, public-access, and high-rise glass balustrade installations
• Structural glass barriers and crowd barriers requiring the thickest available glass
• Marine-grade AISI 316 installations in coastal, pool, and high-humidity environments
• Projects where the glass specification exceeds the capacity of all other Strofix flat-mount clamps

FAQ

What glass thicknesses does this clamp accept?

Two options: 17.52 mm and 21.52 mm laminated safety glass. The 21.52 mm is the thickest glass supported by any clamp in the Strofix range. A "without rubbers" option is also available for ordering the clamp body only.

Why is this AISI 316 only?

This is the only glass clamp in the Strofix range available exclusively in AISI 316 (no AISI 304 option). Installations requiring 17.52–21.52 mm laminated glass are typically high-specification commercial projects where marine-grade stainless steel is the standard material specification.

How does this compare to the 55×65 mm flat clamp?

The 55 × 65 handles glass from 12 to 17.52 mm in AISI 304 or AISI 316. This 60 × 70 handles 17.52 and 21.52 mm in AISI 316 only. There is a small overlap at 17.52 mm — for 17.52 mm glass, either clamp may be used, but this 60 × 70 provides a larger body and is AISI 316 only.

What is 21.52 mm glass?

21.52 mm is a heavy laminated safety glass configuration — typically two thick tempered panes bonded with a PVB interlayer. This is specified for structural glass barriers under extreme loading conditions such as high wind zones, crowd barriers, and high-security applications.

Does this include support?

Yes. The clamp includes a security plate for secondary glass retention.

How is the clamp attached?

The clamp is attached to the mounting surface by screwing. Fastening hardware is included.

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.
