Glass clamp 55x65mm, Flat, Satin, With support

The Strofix glass clamp 55×65 mm flat with support is a stainless-steel glass panel holder designed for the thickest glass panels in the Strofix range. The clamp mounts on flat surfaces such as walls, square posts, and flat-sided structural members, and holds glass panels from 12 to 17.52 mm thick. The distance between the mounting surface and the glass panel is 20 mm. Available in AISI 304 or AISI 316 with a satin finish. Includes support. Attached by screwing (elements for screwing included).

The 55 × 65 mm body is the largest flat-mount glass clamp in the Strofix range, purpose-built for heavy laminated safety glass panels used in commercial, public-access, and high-rise glass balustrade installations. The glass thickness options include 12 mm single tempered glass and three laminated safety glass configurations: 13.52 mm, 16.76 mm (88.2 designation, 8+8+0.76 PVB), and 17.52 mm. These thick glass panels are typically specified by structural engineers for balustrades carrying high wind loads or crowd loads. The glass range does not overlap with the smaller clamps (which top out at 12.76 mm) — this clamp starts where the others end. 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:

• Commercial and public-access glass balustrades with heavy laminated safety glass
• Glass panels 12–17.52 mm thick requiring the largest flat-mount clamp body
• High-rise balcony and terrace railings with thick laminated glass specified for wind loads
• Structural glass balustrades where 16.76 mm (88.2) or 17.52 mm glass is required
• Coastal installations requiring AISI 316 for heavy glass clamping

FAQ

What glass thicknesses are supported?

The clamp accepts glass from 12 to 17.52 mm: 12 mm single tempered glass and laminated safety glass in 13.52, 16.76, and 17.52 mm. The 16.76 mm option corresponds to laminated designation 88.2 (8+8+0.76 PVB interlayer). This is the thickest glass range in the Strofix clamp family.

How does this compare to the other flat clamps?

The 45 × 45 handles 6–10.76 mm. The 45 × 63 and 52 × 52 handle up to 12.76 mm. This 55 × 65 starts at 12 mm and extends to 17.52 mm — it is designed exclusively for thick glass that the smaller clamps cannot accommodate. There is a small overlap at 12 mm only.

What is the 88.2 laminated glass designation?

88.2 refers to laminated glass composed of two 8 mm glass panes bonded with a 0.76 mm PVB interlayer, producing a total thickness of 16.76 mm. This is a standard specification for structural glass balustrades.

Does this include support?

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

Which steel grades are available?

AISI 304 and AISI 316. Choose AISI 316 for coastal, pool, or high-humidity installations.

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.
