Glass adaptor D50, SS, color

The Strofix D50 colour glass adaptor is a stainless-steel point fixing used to mount 8–21.52 mm glass panels to flat surfaces in balustrades, façades, canopies, and architectural glazing, with a decorative colour finish that matches specific interior and exterior colour schemes. Supplied in AISI 304 with a fixed 10 mm spacer, an M10 × 45 mm screw, a Ø50 mm flat cover, and a selectable colour finish: matte black (RAL 9005 MAT), anthracite grey (RAL 7016), white (RAL 9003), gold satin (PVD), or gold polished (PVD).

Two coating technologies are used across the range. The matte black, anthracite grey, and white options are powder-coated to RAL standards, giving a durable paint finish suited to colour-matched railing and façade systems. The gold satin and gold polished options use PVD (Physical Vapour Deposition) coating — a thin, hard metallic layer deposited under vacuum that provides a wear-resistant decorative surface with a metallic lustre.

Each adaptor secures the glass through a single Ø19 mm pre-drilled hole, with an 18 mm inner bushing diameter, and is clamped by an M10 × 45 mm stainless-steel screw. The wide 8–21.52 mm glass range covers standard toughened glass and thicker structural laminated buildups. AISI 304 is the standard chromium-nickel stainless steel and provides reliable corrosion resistance for indoor installations and standard protected outdoor environments.

Use cases:

• Balustrades where hardware must match a black, anthracite, white, or gold colour scheme
• Commercial glass partitions in offices, retail, and hospitality spaces with coordinated metal finishes
• Architectural glazing in hotels, restaurants, and public buildings where colour-matched fixings are specified
• Heavy-duty balustrades with thick laminated glass up to 21.52 mm in colour-coordinated interiors
• Glass canopies and entrance awnings where visible fixings are part of the design language
• Stair side glazing and mezzanine edge protection in coordinated colour palettes

FAQ:

What glass thickness does this adaptor support?

The D50 colour adaptor is suitable for glass panels from 8 mm to 21.52 mm thick, covering standard toughened glass and thicker structural laminated glass buildups commonly used in balustrades, façades, and canopies.

Which colour finishes are available?

Five options are selectable: matte black (RAL 9005 MAT powder coat), anthracite grey (RAL 7016 powder coat), white (RAL 9003 powder coat), gold satin (PVD), and gold polished (PVD). The powder-coated finishes provide a durable painted surface; the PVD finishes provide a hard, wear-resistant metallic layer with a lustrous appearance.

What is the difference between powder coat and PVD?

Powder coating (RAL 9005 MAT, RAL 7016, RAL 9003) applies a thick paint layer that can be colour-matched to standard RAL charts. PVD (gold satin, gold polished) deposits a thin metallic film under vacuum, giving a harder, more scratch-resistant surface with a metallic sheen. PVD finishes are typically specified for interior use where the metallic lustre is a design feature.

What size hole must be drilled in the glass?

A minimum Ø19 mm hole is required for the M10 screw. The adaptor uses an 18 mm inner bushing diameter. The hole must be pre-drilled by the glass supplier before tempering — toughened glass cannot be cut or drilled after heat treatment.

Is the spacer height adjustable?

No. This SKU ships with a fixed 10 mm un-threaded spacer, which sets the standoff distance between the wall and the glass. The spacer cannot be adjusted after installation.

Can I install it myself?

Yes, with basic tools: a drill with the correct bit for your wall material, a torque wrench, an M10-rated wall anchor matched to the substrate, and pre-drilled glass. Handle the coated components with care to avoid scratching the finish during installation. Thick laminated glass panels should be handled with two people.

About painted glass adaptors

A painted glass adaptor is a colour-coated stainless-steel point fixing that attaches a glass panel to a supporting structure while matching a specific architectural colour scheme. The paint layer is applied over stainless steel, retaining the base metal's corrosion resistance while replacing the standard metallic appearance with a decorative finish.

Strofix supplies painted glass adaptors in two diameters — D30 and D50 — with spacer heights of 10, 15 and 32 mm. Available colours include matte black, anthracite, white, gold polished, gold satin, copper polished and dark chrome polished; the D50 range also includes a variant with an inner thread.

The right variant depends on the required colour, adaptor diameter, spacer height and whether an inner-thread connection is needed.
