Frame anchor Koelner/Rawlplug FF1 polyamide 8×160 mm with funnel, galvanized screw

Koelner/Rawlplug FF1 frame anchor in polyamide, size 8×160 mm, supplied with a funnel-shaped collar and a galvanized screw, is designed for fastening fixtures and frames into solid masonry and concrete. The polyamide body offers mechanical stability and the supplied galvanized screw provides additional corrosion resistance for typical indoor and sheltered outdoor applications. The funnel collar helps achieve consistent seating of fixtures and distributes compressive loads around the anchor mouth.

Advantages

The FF1 frame anchor combines a durable polyamide sleeve with a matching galvanized screw to give reliable load transfer into masonry and concrete substrates. Its funnel-shaped collar facilitates correct installation depth and even pressure distribution. The anchor is suitable for typical construction requirements where a compact, ready-to-install frame fastener is needed, and the materials are chosen to reduce the risk of corrosion in standard environments.

Suitable for

• Anchoring door and window frames to solid brick or concrete walls
• Mounting metal or wooden frames and window sills
• Securing lightweight brackets and fixtures in structural masonry
• Indoor installations and sheltered outdoor locations where galvanized fasteners are acceptable

When it may not be suitable

This anchor is intended for use in solid masonry and concrete; it is not designed for hollow block or gypsum board without appropriate backing or special anchors. For highly corrosive environments, coastal locations, or chemical exposure, stainless steel fasteners or specialized corrosion-resistant anchors should be considered instead.

Key specifications

• Anchor material: polyamide sleeve
• Anchor diameter and length: 8 mm × 160 mm
• Collar type: funnel-shaped seating collar
• Fastener included: galvanized steel screw
• Intended substrates: solid masonry and concrete

How to use

Drill a hole in the masonry or concrete to the recommended diameter and depth for an 8×160 mm anchor, clean the hole of dust and debris, insert the polyamide sleeve until the funnel collar seats against the fixture or substrate, position the frame or fixture, and tighten the supplied galvanized screw to expand the sleeve and secure the anchor. Ensure the drilling depth leaves room for the full sleeve length and check that the fixture sits flush against the funnel collar before final tightening.

What to consider before purchase

• Confirm substrate type is solid masonry or concrete and suitable for expansion anchors
• Verify that an 8×160 mm sleeve length and diameter meet load and embedment requirements
• Assess environmental exposure to determine whether galvanized fasteners are sufficient
• Ensure drilling tools and bits compatible with masonry/concrete are available

Usage recommendations

For optimal performance when installing the Koelner/Rawlplug FF1 polyamide frame anchor, use an appropriate hammer drill and carbide masonry bit, remove dust from the hole before insertion, avoid over-torquing the screw to prevent sleeve damage, and follow local building codes for anchor spacing and edge distances.
