Screw anchor FISCHER 544552 long-shank wall plug set, 4 pieces (SXRL 8 x 120)

The fischer frame fixing SXRL-T is a long-shank anchor designed for multiple non-structural fixings in masonry, concrete and aerated concrete. Supplied with a zinc-plated steel safety screw with TX drive, the fixing transfers loads via two expansion zones that work together to create an extended expansion element in solid and aerated materials. The plug geometry distributes forces evenly and the ribs on the sleeve prevent rotation during installation. The product is supplied as a set of four anchors and screws suitable for interior frame and fixture installations such as window frames, coat racks, wall cupboards and TV consoles.

Advantages

The SXRL-T provides reliable load values for multiple fixings in concrete and masonry and features a long expansion element for versatile use across different base materials. Its geometry ensures even load transfer, reducing the risk of damaging thin-walled masonry. Ribs on the plug simplify assembly by preventing rotation while inserting the fixing. The zinc-plated steel safety screw offers corrosion resistance appropriate for internal applications.

Suitable for

• Fixing window and door frames in masonry or concrete
• Mounting coat racks, shelves and wall cupboards
• Installing TV consoles and other non-load-bearing fixtures
• Use in aerated concrete and perforated masonry

When it may not be suitable

The SXRL-T is intended for non-structural applications; it is not designed for load-bearing structural connections or where structural design approvals are required. External or highly corrosive environments may require stainless or specially coated fasteners rather than the zinc-plated screw supplied.

Key specifications

• Anchor type: long-shank frame fixing with expansion sleeve
• Material (screw): zinc-plated steel
• Drive type: TX (Torx)
• Length: 120 mm (overall)
• Pack quantity: 4 pieces (anchors and screws)
• Suitable base materials: concrete, solid masonry, perforated masonry, aerated concrete

How to use

Drill the correct diameter hole to the required depth, clean the hole of dust and debris, then insert the SXRL-T sleeve flush with the surface. Place the frame or fixture in position and drive the included TX screw into the anchor until the sleeve expands and secures in the base material. Ensure the screw is tightened to the recommended torque for the intended load and base material, taking care not to over-torque.

What to consider before purchase

• Confirm the fixing length (120 mm) is suitable for the frame depth and base material.
• Verify that the zinc-plated screw is acceptable for the installation environment (interior use recommended).
• Ensure the anchor diameter and drill bit match the product requirements and the substrate condition.

Usage recommendations

Use the SXRL-T for interior frame and fixture installations in concrete, solid and perforated masonry, and aerated concrete. For exterior or high-corrosion environments choose a stainless or specially coated alternative and follow the manufacturer’s guidance on drilling diameter and tightening torque for safe, repeatable fixings.
