Stackable Threaded-Rod-Mount Clamping Hangers
Mount these hangers on top of one another to organize multiple lines of pipe, tubing, and conduit at any angle. They include one or two clamping screws, which tighten around material and provide a more secure hold than loop hangers. Mount with threaded rod (not included), or some come with a stacking screw.
Two-piece clamps don’t require access to the ends of your pipe to install. Stacking clamps are flat on top and bottom. The bottom has a mounting hole that can be used with 1/4"-20 threaded rod to mount or a 10-24 fastener to connect to the top of a stacking clamp. The top has a stacking hole that can be used with 10-24 threaded rod to mount or a 10-24 connecting fastener to connect to the bottom of another clamp.
303 stainless steel hangers have excellent corrosion resistance.

Stackable Vibration-Damping Threaded-Rod-Mount Clamping Hangers
Connect these hangers together to organize multiple lines of pipe, tubing, and conduit. They have a tight-fitting, santoprene body that reduces vibration and prevents corrosion caused by metal-to-metal contact. The smooth surface of the rubber prevents debris buildup and makes cleaning easy.
Stacking clamps have stacking hardware and a plate for attaching to an end clamp or to other stacking clamps. They must be connected to an end clamp to mount.
Note: All hangers must be the same length and height. Do not exceed the capacity of the individual hanger in multiple hanger applications.
