Rawl R-FFS-K-A4 Frame Fixing with Short Expansion Zone & Stainless Hex Screw

The Rawl R-FFS-K-A4 is a frame fixing designed for secure installation in thin-walled and hollow base materials, where minimal expansion depth is required.

The short anchoring zone — just 40 to 50mm — makes this fixing particularly well-suited to installations where conventional fixings would risk over-expansion or substrate damage. The plug's multi-axis expansion design ensures reliable load distribution across a range of base materials, including concrete, solid brick, hollow block, and aerated concrete, covering all categories under ETAG 020 (A, B, C, D).

The A4 stainless steel hex screw provides strong corrosion resistance, making this fixing appropriate for external applications and high-humidity environments such as outdoor window and door frame installations. The collared plug accommodates hard fixing materials such as steel, while the internal geometry is engineered to seat the screw head accurately for consistent, controlled drive depth.

This fixing is suitable for contractors and tradespeople installing lightweight frames, windows, and door linings where speed and installation reliability are priorities. Compatible with a punch-tool for use in aerated concrete, it supports quick, efficient assembly on site.
