Get Your Ducts in a Row
Whether they are rubber ducks or metal ducts, you never want them to fall through the ceiling. Luckily, nVent CADDY products offer many solutions for hanging round duct. In this video, Rick primarily focuses on two:

nVent CADDY SPEED LINK SLK System is the ideal choice for hanging round duct from a variety of structures. The system comes with eleven end fittings that can easily attach to common structures. Rick also explains that unlike competitors, the CADDY SPEED LINK system can be used in the “infinite loop” and “sling” formations that make hanging ductwork even easier.

Strap Hangers can also be used to support the round duct. The CADDY catalog offers a number of solutions for attaching the strap to beam, purlin, or concrete.
