Hollow Drop-In Internally Threaded Anchor
Product Details
The HDIA hollow drop-in anchor is an internally threaded, flush-mount expansion anchor designed for attaching threaded rod to support a variety of conduit, cables and lighting. This anchor is ideal for use with hollow base materials such as CMU and hollow-core plank as well as in solid base materials such as brick and both normal-weight and lightweight concrete. The HDIA can easily be installed in both hollow and solid materials with a setting tool.
Key Features
- Suitable for suspending conduit, cable trays, pipe supports, fire sprinklers and suspended lighting into concrete
- Expansion design allows HDIA to anchor into CMU, hollow-core plank, brick, normal-weight concrete and lightweight concrete
- Internally threaded anchor allows for easy bolt removal
Material
- Die-cast Zamac 3 alloy shell with carbon-steel cone or Type 304 stainless-steel cone
Installation
- Installation Instructions — Solid Base (using solid setting tool)
