Traditional methods for installing branch line restraints in fire sprinkler systems are cumbersome and time-consuming. Contractors often cut (and re-cut) threaded rod to precise measurements to restrain the sprinkler pipe with a loop hanger and surge restraint. Traditional methods also commonly require five or more parts per restraint.
To avoid these labor-intensive methods, Pentair has streamlined the process and developed the Branch Line Restraint System, part of the nVent CADDY line of hanging and bracing solutions for the fire protection market. Ideal for restraining 1” (25 mm) through 2” (50 mm) branch lines, this innovative system is significantly faster and easier to install than current methods. It attaches directly to steel bar joists, I-beams or purlins, as well as concrete and wood structures. The hardware is installed with only one tool, a 5/16” (8 mm) socket drill driver, which provides significant labor savings and convenience. It features a simple, two-step installation process, allowing a time savings of up to 80% compared to other methods.
Unlike most solutions that only accept 3/8” (M10) threaded rod, the versatile Branch Line Restraint System features a swivel attachment that can be rotated to accept 3/8” or 1/2” (M10 or M12) threaded rod. This allows greater restraint distances from the pipe to structure with 1/2” (M12) threaded rod.
The system meets the requirements of NFPA® 13, making it ideal for new construction applications. The total system is cULus® Listed and FM® Approved, and has been pre-approved by the state of California (OSHPD OPA-2629-10).
