Stainless Steel Clamping Two-Piece Pipe Collars
Often used in corrosive environments to support pipe passing through walls and floors, these collars are 303 stainless steel and sized specifically for a tight fit around pipe. They can also easily be machined to hang signs. Because they’re two pieces, you don’t need to have access to the ends of your pipe to install them. Tighten the clamping screws to secure.

Steel Clamping Two-Piece Pipe Collars
Sized to fit snugly around pipe, these collars are often used to support pipe passing through floors and walls. They can also easily be machined to hang signs. These collars are two pieces, so you don’t need to have access to the ends of your pipe to install them. Tighten the clamping screws to secure. All collars are black-oxide steel, so they have some corrosion resistance.

Steel Clamping Two-Piece Pipe Collars with Wrench Flats
To avoid gouging and marring your pipe while making adjustments, these collars have flats where you can grab and rotate the pipe with a wrench. They're sized precisely for a tight fit around pipe, so they're often used to support pipe passing through floors and walls. They can also easily be machined to hang signs. Since they’re two pieces, you don’t need to have access to the ends of your pipe to install them. Tighten the clamping screws to secure. They’re black-oxide steel, so they have some corrosion resistance.

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. End clamps are flat on one side and round on the other. The flat side 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 round side provides a finished look. 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.
