Drop In Anchor
Description
The Drop-In Anchor is a heavy-duty internal expansion anchor designed for fastening threaded rods and bolts into solid concrete. Manufactured from high-quality carbon steel or stainless steel, it provides secure and reliable anchoring performance in structural and suspension applications.
The anchor is internally threaded and installed flush with the concrete surface using a setting tool. Once expanded, it creates a strong mechanical bond inside the concrete, making it ideal for overhead installations such as strut channel systems, cable trays, piping supports, and HVAC suspension systems.
