Rubber for slot tube, glass 11-12,76mm

The Strofix rubber for slot tube, glass 11-12,76mm is a clamping rubber gasket for glass-top handrails, sized for glass panels 11–12.76 mm thick. It fits the slot (channel) of the 40 × 40 mm and Ø42.4 mm handrail profiles, cushioning and gripping the glass edge within the rail. Made from rubber with a U=24 profile. Priced per metre.

In a glass-top handrail, the rail profile sits over the top edge of the glass panel via a channel, and this rubber gasket fills the gap between the glass and the metal slot. It grips the glass securely, absorbs vibration and movement, and protects the glass edge from direct metal contact. The 11–12.76 mm size covers thicker single-glazed and laminated panels — including 12.76 mm (66.2) laminated safety glass, a common balustrade specification. Other gasket sizes in the range cover glass from 8 mm up to 21.52 mm. The gasket is supplied by the metre and cut to the length of the handrail run.

Use cases:

• Glazing gasket for 11–12.76 mm glass in a slot-tube (channel) handrail
• 12.76 mm (66.2) laminated safety glass balustrade handrails
• Cushioning and gripping the glass edge inside the handrail profile
• Protecting the glass edge from direct metal contact in the rail slot
• Glass-top handrail assembly on 40 × 40 mm and Ø42.4 mm profiles

About Handrails

A handrail is the graspable top rail of a balustrade system, running along the upper edge of railing posts or the top of a glass panel to provide a secure handhold. The handrail profile sits on handrail supports or is fixed directly to the glass via a channel bar, and fittings at each joint — elbows, end caps and axial connectors — allow the rail to follow corners, stair pitches and direction changes.

Strofix supplies handrails and handrail components in two profile systems: a 40×40 mm flat square profile and a Ø42.4 × 15 mm oval (D-shaped) profile for glass-top mounting, both in AISI 304 stainless steel with a satin finish.

The range includes applied handrail lengths (2500 mm), channel bars in AISI 304 and aluminium for glass-top fixing, clamping rubbers for glass thicknesses from 8 to 21.52 mm, end caps, axial fastenings, handrail fittings, horizontal and vertical 90° fittings, and flush adjustable elbows. The correct components depend on handrail profile, mounting method (post-top or glass-top) and the railing layout.
