The Simpson Strong-Tie tie-wire anchor is a wedge-style expansion anchor for use in normal-weight concrete or in concrete over metal deck. With a tri-segmented, dual-embossed clip, the tie-wire anchor is ideal for the installation of acoustic ceiling grid and is easily set with the claw of a hammer.

Key Features: 

1/4″ eyelet for easy threading of wire

Sets with claw of hammer

Tri-segmented clip — each segment adjusts independently to hole irregularities

Dual embossments on each clip segment enable the clip to undercut into the concrete, increasing follow-up expansion
