Glass adaptor - cover, D50 spherical, SS, satin

The Strofix glass adaptor cover D50 spherical with flange satin is a stainless-steel finishing cap with a domed profile and an integrated flange for D50 glass adaptor assemblies, providing the visible face on the glass side of the fixing. Manufactured from AISI 304 with a satin finish, Ø 50 mm diameter, available with an internal M8 or M10 thread.

The cover screws onto the threaded stud or screw that passes through the glass panel, clamping the glass, gaskets, and distancer together as a complete adaptor assembly. Select M8 or M10 to match the thread of the stud used in the adaptor assembly — the two options are not interchangeable. The spherical profile produces a domed surface that protrudes slightly from the glass face, while the integrated flange provides an extended seating surface between the cover and the glass, increasing the contact area for a more stable clamping interface. The cover is sold individually as a replacement or spare part for Strofix D50 glass adaptor assemblies — it is not a complete adaptor kit.

The satin finish reduces visible fingerprints and micro-scratches, matching the appearance of other satin-finished D50 components for a uniform look across the entire fixing point.

Use cases:

• Completing or repairing D50 glass adaptor assemblies on balustrades and partitions
• Replacing a damaged or scratched flanged spherical cover on an existing Strofix D50 point fixing
• Choosing a flanged domed appearance on D50 adaptor assemblies using M8 or M10 screws
• Stocking spare covers for maintenance of installed D50 glass fixing systems
• Façade, canopy, and staircase glazing point fixings using D50 adaptors

FAQ:

What is this cover used for?

The cover is the visible finishing cap on the glass side of a Strofix D50 glass adaptor assembly. It screws onto the M8 or M10 threaded stud protruding through the glass, clamping the glass panel, rubber gaskets, and distancer into a single assembly. It is not a complete adaptor — it is one component sold separately.

Which screw size should I choose?

Select M8 or M10 to match the threaded stud used in your D50 adaptor assembly. The two thread sizes are not interchangeable — ordering the wrong size means the cover will not fit. Check the existing stud or the distancer thread specification before ordering.

How does this flanged cover differ from the standard D50 spherical cover?

This cover has an integrated flange — a wider lip at the base of the dome that provides an extended seating surface against the glass. It is available in M8 and M10 thread sizes. The standard D50 spherical cover (without flange) is available in M10 and M12 thread sizes. The two are separate products with different thread options and contact profiles; they are not interchangeable without verifying the screw size.

What is the difference between spherical and flat D50 covers?

The spherical cover has a domed surface that protrudes slightly from the glass. The flat D50 cover sits flush against the glass with a level profile. This flanged spherical variant adds a wider base contact area compared to both the standard spherical and flat covers.

Which Strofix glass adaptors is it compatible with?

This cover fits Strofix D50 glass adaptor assemblies (Ø 50 mm cover diameter) that use an M8 or M10 screw, depending on the variant selected. It is not compatible with D30 or D40 adaptors.

Can I replace just the cover without disassembling the entire adaptor?

The cover unscrews from the threaded stud on the glass side. Replacing it requires access to the glass face only — the wall-side fixings and distancer remain in place. A new cover threads onto the same stud, provided the thread size matches (M8 or M10).

About glass adaptor covers

A glass adaptor cover is a stainless-steel cap that screws onto the visible face of a glass adaptor assembly, concealing the fixing bolt and giving the point fixing a clean, finished appearance. The cover threads onto the bolt that passes through the glass, so it is the component the viewer sees from the interior or exterior side of the panel.

Strofix supplies glass adaptor covers in three diameters — D30, D40 and D50 — in AISI 304 satin-finish stainless steel, with flat and spherical head profiles. Covers are sold individually as spare or replacement parts, and thread onto M8, M10 or M12 bolts depending on the variant.

The correct cover depends on adaptor diameter, head profile (flat or spherical) and the bolt size used in the assembly.
