Stackable Vibration-Damping Clamp Pipe Hangers


Shown Connected	Stacking Clamps

Stack these pipe hangers to organize multiple lines of pipe, tubing, and conduit. The rubber tightly fits around lines to minimize disruptive noise and equipment damage. It also prevents debris build-up and corrosion from metal-to-metal contact.

Stacking Clamps—Include stacking hardware and a plate for attaching to an end clamp or other stacking clamps. To mount, the stacked clamps must be connected to an end clamp.

Stackable Clamp Pipe Hangers


Shown Connected	Two Piece Stacking Clamps

Stack these hangers to organize multiple lines of pipe, tubing, and conduit at any angle. Mount with threaded rod (not included) or connect two hangers using the included stacking screw.

Two Piece—You don't need to access the end of your line to install these clamps. Detach the two halves and place them around pipe.

303 Stainless Steel—Withstand mild chemicals and solvents and won't rust in wet environments.

Stacking Clamps— Flat on top and bottom. Twist threaded rod through the stacking hole on top or the mounting hole on the bottom. You can also use a fastener to connect the top of one hanger to the bottom of another hanger.
