nVent ERICO TSR1220 Captive threaded nuts enable fastening to threaded rod supports without loose parts. Telescopes to the desired length and is locked in place by snapping closed a spring retainer clip. Standard strut profile runs the entire length of the part, allowing most standard fittings to be placed anywhere between the rods. Integrated ruler displays space between hanger rods in inches and centimeters. Supports up to seven 2" (50 DN) conduits, six 2" (50 DN) water filled pipes at 10' (3 m) spacing, or up to 18 (450 mm) cable tray. Conduit can be supported on the top and bottom, eliminating the need for double sided strut. Conduit and pipe can be placed directly on the strut profile, saving vertical space in buildings with limited room for installation.
