Hollow-Set™Drop-in

Base Material:
Concrete, Block, Brick, Precast Hollow Core Plank, Stone

Size Range:
1/4" to 5/8"

Anchor Material:
Zamac Alloy with Carbon Steel or Stainless Steel Cones
The Hollow-Set Drop-in anchor is designed for anchoring in hollow base materials such as hollow concrete block, brick with weep holes and hollow core pre-cast concrete plank. It can also be used in solid base materials.
Hollow masonry materials often have a minimum outer wall thickness of 1 1/2". During the drilling process, spalling on the back side of the wall often decreases the wall thickness available for anchoring to 1" or less. The design of the Hollow-Set Dropin overcomes this problem.
