Glass adaptor D35, adjustable, SS, satin

The Strofix D35 adjustable glass adaptor is a stainless-steel point fixing used to mount 8–12.76 mm glass panels to flat surfaces in balustrades, partitions, and architectural glazing, with a continuously adjustable spacer that lets the installer set the exact wall-to-glass distance on site. Supplied in AISI 304 with a satin finish, a Ø35 mm flat cover, an M8 screw, and three selectable spacer ranges (20–25 mm, 30–35 mm, or 50–55 mm).

Unlike fixed-spacer adaptors, the D35 adjustable model allows the standoff distance to be set to any value within the chosen range — for example, anywhere from 20 to 25 mm with the first variant — by extending or retracting the telescoping spacer during installation. This makes it well suited to installations where exact wall dimensions are unknown at order time, or where multiple panels along a run must be aligned to the same standoff despite varying substrate depths. Each adaptor secures the glass through a single Ø17 mm pre-drilled hole, with a 16 mm inner bushing diameter, and is clamped by an M8 stainless-steel screw through the un-threaded spacer.

AISI 304 is the standard chromium-nickel stainless steel and provides reliable corrosion resistance for indoor installations and standard protected outdoor environments away from coastal conditions. The satin finish reduces visible fingerprints and micro-scratches compared to polished stainless steel and suits architectural glazing where a clean, neutral look is required.

Use cases:

• Balustrades where exact wall-to-glass distance varies along a run
• Glass partitions on uneven or out-of-plumb walls requiring on-site adjustment
• Residential and commercial staircase side glazing with variable substrate depths
• Glass canopies and entrance awnings on prepared substrates of uncertain thickness
• Retrofit installations where wall dimensions cannot be confirmed before ordering
• Projects where a single SKU must cover a range of standoff distances without stocking multiple fixed-spacer variants

FAQ:

What glass thickness does this adaptor support?

The D35 adjustable adaptor is suitable for glass panels from 8 mm to 12.76 mm thick, covering standard toughened glass and common laminated glass buildups used in balustrades and partitions.

Which spacer range should I choose?

Each variant covers a 5 mm adjustment window: 20–25 mm, 30–35 mm, or 50–55 mm. The spacer can be set to any distance within that range during installation. Measure the nominal wall-to-glass dimension and select the range that covers it — the adjustability compensates for the final 5 mm of tolerance.

How does "adjustable" differ from "slightly adjustable" on other Strofix adaptors?

Other Strofix adaptors listed as "slightly adjustable" use a threaded spacer that can be rotated for fine-tuning within a small range. This D35 is listed as fully "adjustable" (Adjustable: Yes) and uses a telescoping spacer mechanism that covers a defined 5 mm range per variant, specifically designed to set the exact standoff distance on site.

What size hole must be drilled in the glass?

A minimum Ø17 mm hole is required for the M8 screw. The adaptor uses a 16 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.

What stainless steel grade is used?

This SKU is supplied in AISI 304, the standard chromium-nickel stainless steel. AISI 304 provides reliable corrosion resistance for indoor installations and standard protected outdoor environments. For coastal, pool, or chloride-rich locations, a higher-grade stainless steel such as AISI 316 should be specified.

Can I install it myself?

Yes, with basic tools: a drill with the correct bit for your wall material, a torque wrench, an M8-rated wall anchor matched to the substrate, and pre-drilled glass. Set the spacer to the required standoff distance, then tighten the assembly. Handle glass panels with two people and follow the glass supplier's recommended torque to avoid cracking

About adjustable glass adaptors

An adjustable glass adaptor is a stainless-steel point fixing with a variable spacer height that allows the wall-to-glass offset to be fine-tuned during installation. Unlike fixed-spacer adaptors, the adjustable design compensates for uneven substrates, insulation build-ups and alignment tolerances, reducing the need for shimming or rework on site.

Strofix supplies adjustable glass adaptors in three diameters — D35, D40 and D50 — in AISI 304 or AISI 316 stainless steel with a satin finish. Spacer adjustment ranges span from 20–25 mm up to 52–58 mm, and selected variants feature a spherical head with an inner thread for additional angular flexibility.

Choosing between variants depends on the required offset range, glass-panel size and whether the environment calls for AISI 316 corrosion resistance.
