Stackable Clamp Pipe Hangers


Shown Connected	Hinged End Clamps

Two Piece End Clamps	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.

Hinged—Combine the flexibility of a two-piece clamp with the simplicity of a one-piece clamp. These are easy to assemble, reposition, and take apart.

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.

End Clamps—Flat on one side and round on the other. Mount the flat side to threaded rod or connect it to the top of a stacking clamp. The round side has a finished look.

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.
