ICCONS Cavity Set Drop-In Anchors feature 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. 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
