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. Hinged clamps have a triple-link design and a captive clamping screw to combine the flexibility of a two-piece clamp with the simplicity of a one-piece clamp. All are easy to assemble, reposition, and take apart.
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.

Vibration-Damping Threaded-Rod-Mount Clamping Hangers
Rubber cushions fit material tightly to reduce vibration and provide a more secure hold than loop hangers. The cushions also protect material from sharp edges and prevent corrosion caused by metal-to-metal contact. Hangers have a threaded nut on top for mounting with threaded rod.
Zinc-plated steel hangers have good corrosion resistance.
Hangers with EPDM-SBR cushion have one cushion that completely surrounds material to compensate for material expansion and contraction.

Stainless Steel Threaded-Rod-Mount Loop Hangers
Use these hangers in corrosive environments and where chemicals are present. They're also known as teardrop hangers. Combine with a threaded rod or other fastener to hang from the ceiling. To mount, slide threaded rod into the unthreaded holes on top of the hanger and secure with a pair of nuts (sold separately). 316 stainless steel clamps have excellent corrosion and chemical resistance.

Strut-Mount Metal Routing Clamps for Insulated Pipe
Secure insulated pipe to strut channel without pinching the insulation or exposing the pipe. These clamps are sized for use with insulated pipe and have a plastic insert that creates a seal around the insulation to prevent the pipe from sweating, which can cause mold and corrosion. To install, slide the clamp into the strut channel, insert the insulated pipe, and tighten the clamping screw to secure. All are zinc-plated steel and TPO for good corrosion resistance.

Snug-Fit Vibration-Damping Loop Clamps
A molded cushion reduces vibration and wear from clamp edges, plus provides a tighter fit around material than standard vibration-damping loop clamps. Clamps surround lines completely while holding them close to the mounting surface.
Aluminum clamps have good corrosion resistance. 304 and 321 stainless steel clamps have excellent corrosion resistance.
Neoprene cushions are for use in environments where clamps are exposed to oil and ozone. EPDM cushions are for use in environments where clamps are exposed to water and steam. They withstand ozone and aging. Silicone cushions withstand ozone, sunlight, oxidation, and high temperatures.
