TDS 1048.1: Cavity Set Drop-in Anchor
Cavity Set Drop-In Anchors Brochure
The Cavity Set Drop-In Anchor features a slotted, tapered expansion sleeve and a serrated expansion cone in its design. When fastening in hollow masonry materials with a maximum outer wall thickness of 35mm, the drilling process may lead to spalling on the back side of the blockwork, reducing the blockwork wall thickness for anchoring to 25mm or less. This poses a challenge for traditional anchors that struggle to function effectively in base materials of such reduced thickness. The Cavity Set Drop-In Anchor addresses this issue by tailoring the expansion sleeve length to be compatible with the outer wall thickness of most hollow block base materials. The expansion sleeve is designed to minimise compression forces exerted on the base material during expansion. As the anchor is tightened, the specially tapered cone is drawn into the expansion sleeve, creating a locking action against the drill hole walls.
