Koelner/Rawlplug FF1 frame anchor with a funnel head, size 10×120 mm, pack of 12 is designed for load-bearing fixings in solid substrates. The frame anchor combines a metal sleeve and an expanding element to create a reliable mechanical anchor suitable for mounting window and door frames, facade elements and similar structural fittings. Supplied in a pack of 12, this anchor is intended for professional installation and renovation projects where secure, through-type fastening is required.
Advantages
The FF1 funnel-head frame anchor provides consistent expansion in solid materials, ensuring stable clamping force and reduced risk of loosening under dynamic loads. Its funnel head design facilitates easy insertion of the fixture and provides a flush or slightly recessed finish depending on installation method. Packaged in groups of 12, the anchors offer convenience for small to medium installation runs and reduce the need for repeated purchases.
Suitable for
- Mounting window and door frames into concrete or solid masonry
- Fixing facade profiles and metal frames to solid substrates
- Securing load-bearing fittings where through-bolt or screw fastening is used
- Construction and renovation projects requiring mechanical anchors
When it may not be suitable
This frame anchor is intended for use in solid substrates such as concrete and solid brick. It is not suitable for hollow blockwork, cavity walls or lightweight cellular materials without additional lining or special anchors designed for cavities. For highly corrosive environments or outdoor marine exposure, consult material and corrosion-resistance requirements and consider stainless or specially coated anchors.
Key specifications
- Anchor type: frame anchor with funnel head
- Diameter: 10 mm
- Length: 120 mm
- Pack quantity: 12 pieces
- Suitable substrate: solid concrete, solid brick, similar dense masonry
- Installation method: through-bolt or screw fastening with expansion mechanism
How to use
Drill a hole to the specified diameter and depth in the solid substrate, clean the hole of dust and debris, insert the frame anchor until the funnel head sits correctly against the fixture. Place the frame or profile over the anchor, insert the bolt or screw and tighten to activate the expansion mechanism. Verify that the anchor has expanded and the fixture is held firmly; avoid over-tightening which may damage the sleeve or substrate. Follow standard drill sizes and torque recommendations for the selected bolt or screw.
What to consider before purchase
- Confirm substrate type is solid concrete or solid masonry suitable for mechanical anchors
- Match anchor diameter and length to fixture thickness and required embedment depth
- Check compatibility with the bolts or screws you plan to use for through fastening
- Assess environmental conditions for corrosion resistance needs
Usage recommendations
Use appropriate drilling equipment and dust extraction where possible, clean holes thoroughly before insertion, and follow manufacturer torque guidelines for reliable, long-lasting fixings in solid substrates.
