The CADDY TSR1220R1 Telescoping Strut Replacement Bracket is a smart alternative to traditional strut channels, designed for fast and flexible installation in electrical, HVAC, and plumbing support systems. This pre-cut, adjustable bracket eliminates the need to cut long strut lengths, making it easier to transport and store. Featuring captive threaded nuts and a spring retainer clip, it allows tool-free mounting to 3/8-inch threaded rod without loose parts. An integrated ruler displays hanger rod spacing in both inches and centimeters, while the standard strut profile supports conduit and pipe on both top and bottom-saving vertical space in tight installations.
