The Hollow-Set Dropin anchor is designed for anchoring in hollow base materials such as hollow concrete block and precast hollow core plank. It can also be used in solid base materials. Concrete masonry blocks often have a maximum outer wall thickness of 1-1/2". During the drilling process, spalling on the back side of the wall often decreases the wall thickness, leaving only 1" or less for anchoring. The Hollow-Set Dropin is designed to perform in this environment, where most conventional style anchors will not function properly.
Used in conjunction with the Wall Anchors or T-Nuts. Great for any size wood application. We need to know what size wood you are attaching your hold to ie. plywood or 2X lumber.
We offer plain finish bolts for indoor walls and stainless steel bolts for outdoor walls.
Use 1-1/2" for plywood walls
Use 2-1/2" for 2X lumber walls
Longer bolts available.
