The CADDY® BCISN beam clamp from ERICO® is a creative alternative to the "classic" beam clamp. The new design features a finger-close "smart nut" that allows for easy installation of 3/8" threaded rod, for attachment to beam flanges up to 1/2". Without the use of tools or the need for added nuts, the CADDY BCISN easily positions on 3/8" threaded rod and allows for fine-tuning and adjustment after the rod is locked in place.ERICO®.
