Frame anchor Koelner/Rawlplug KDS 10 x 80 mm with long expansion zone and PZ screw, 14 pcs

Koelner/Rawlplug KDS 10 x 80 mm frame anchors come in a pack of 14 and are designed for secure fixing of window and door frames, timber elements and light steel profiles. Each anchor features a long expansion zone that improves load distribution in base materials and is supplied with a PZ-type screw to create a reliable threaded connection between anchor and fixture. The product is intended for use where deeper engagement in the substrate and controlled expansion are needed to resist pull-out and shear forces.

Advantages

The long expansion zone provides improved contact with the surrounding base material, reducing the risk of localized cracking and concentrating stress over a larger area. Inclusion of a PZ screw with each anchor ensures compatible threading and simplifies installation by matching screw geometry. The anchors are suitable for use in common construction substrates where mechanical fastening is required and provide consistent performance when installed according to recommended drill diameters and embedment depths.

Suitable for

• Mounting window and door frames
• Fixing timber structural elements and decking supports
• Fastening light steel profiles and subframes
• Securing sills, casings and trim where deeper anchoring is required

Key specifications

• Anchor diameter: 10 mm
• Total length: 80 mm
• Long expansion zone for improved load distribution
• Supplied with PZ-type screw for threaded connection
• Pack quantity: 14 pieces

How to use

Drill a hole of the appropriate diameter to the specified embedment depth in the base material, remove dust and debris from the hole, insert the anchor until it sits flush with the fixture, and drive the PZ screw to expand the anchor and secure the fixture. Ensure drill bit size and embedment depth match the anchor dimensions and follow substrate-specific guidance for brittle or hollow materials. Tighten the screw evenly to achieve uniform expansion without over-torquing.

Usage recommendations

Use the anchors only in suitable substrates and follow local building codes. For hollow or perforated materials, use additional measures such as sleeve anchors or specific hollow-wall fittings; for cracked or weak concrete consult a structural advisor. Pre-drill with a carbide-tipped masonry bit and clear the hole to ensure correct expansion and holding performance.
