Frame Anchor Koelner/Rawlplug FF1 with flange 10x80 mm, 20 pcs

Koelner/Rawlplug FF1 frame anchor with flange, size 10x80 mm, pack of 20 pieces is a mechanical fixing designed for secure installation of window and door frames, timber components and light structural elements into concrete and masonry. The flange head ensures even load distribution and stable seating, while the 10x80 mm dimensions suit standard frame profiles and installation depths. Supplied in a set of 20, these anchors are intended for through or blind anchoring where a reliable mechanical connection is required.

Advantages

The FF1 frame anchor combines a flanged head and a robust expansion mechanism to deliver consistent holding power in concrete and solid masonry. Its 10 mm diameter with 80 mm length provides sufficient embedment for frame fixtures while the flange improves pressure distribution on the fixture surface, reducing risk of pull-through. Pack quantity of 20 offers enough anchors for small to medium installation jobs and simplifies inventory for installers.

Suitable for

• Fixing window and door frames to concrete or solid brick
• Securing timber elements and subframes
• Mounting light structural fixtures and trims
• Through or blind anchoring where mechanical expansion is required

When it may not be suitable

This frame anchor is intended for use in concrete and solid masonry; it is not designed for hollow or perforated brick without appropriate sleeve or specialist anchors. For applications requiring high shear or tension loads beyond general frame fixing, consult structural fasteners with documented load capacities. Corrosive environments may require stainless or specially coated anchors rather than standard carbon-steel variants.

Key specifications

• Type: frame anchor with flange (mechanical expansion anchor)
• Diameter: 10 mm
• Length: 80 mm
• Head: flanged head for improved seating and load distribution
• Material: metal expansion anchor (standard steel finish)
• Pack quantity: 20 pieces
• Suitable base materials: concrete, solid masonry
• Installation: through or blind installation

How to use

Drill a hole in the base material with a 10 mm drill bit to the required depth, ensuring the hole is clean and free of dust. Insert the frame anchor through the fixture and into the drilled hole until the flange sits flush against the fixture surface. Tighten the anchor according to the manufacturer's recommended torque so the expansion mechanism engages and secures the anchor in the substrate. For blind fixing, confirm embedment depth before final tightening. Check each anchor for firm seating and re-torque if necessary after initial load application.

What to consider before purchase

• Confirm substrate type: suitable for concrete and solid masonry only
• Verify required anchor length and embedment for your frame thickness
• Check if corrosion-resistant material is needed for the environment
• Ensure drill bit and torque tools match the 10 mm diameter specification

Usage recommendations

Use these Koelner/Rawlplug FF1 10x80 mm frame anchors for standard window and door frame installations in concrete and solid brick. Follow proper drilling, cleaning and torque procedures to achieve reliable mechanical performance; where conditions differ from standard solid substrates, select appropriate specialised anchors.
