Duct Hose and Duct Hose Fittings

Crush-Resistant Duct Hose for Air

Step on this polypropylene hose and the flexible plastic spiral will pop back up unharmed.

Bend-and-Stay Very Flexible Duct Hose for Dust

Bend this hose in any direction and it will hold its shape without support.

Wire, Cable, and Hose Routing & Protecting

Grommets for Medium-Wall (IMC)
and Thick-Wall (Rigid) Steel Conduit

Connect to the end of conduit or a fitting to protect wires from abrasion when being pulled.

Grommets for Thin-Wall (EMT) Steel Conduit

Slide these grommets into conduit ends to protect wire and cable from abrasion when being pulled.

Wrap-Around Low-Voltage Raceway

Surface mount with the adhesive back to route low-voltage data and control cable where you can't get inside walls.

Corner-Mount Wrap-Around Low-Voltage Raceway

The triangular shape fits into corners.

Flexible Slotted Wire Duct

Route wire and cable around curves with this bendable wire duct.

Hinged Interlocking Corrugated Sleeving

A hinge along the entire length makes this one-piece sleeving easy to open for installation. Interlocking ridges overlap along the opening to protect contents from dust and dirt. The corrugated construction gives it the impact and abrasion resistance of conduit, with more flexibility.

Two-Piece Interlocking Corrugated Sleeving

The two halves of this sleeving nest into each other, fully enclosing contents. It has interlocking ridges that overlap to keep out dust and dirt. The corrugated construction gives it the impact and abrasion resistance of conduit, with more flexibility.

Routing and Suspending

Chemical-Resistant Plastic Routing Clamps

For use on a single line, these polypropylene clamps withstand moisture and most chemicals. They're commonly used to route tubing in compressed air systems. A folding arm closes to secure material.

Two-Line Chemical-Resistant
Plastic Routing Clamps

Route two lines of tubing with a single clamp. Commonly used in compressed air systems, these polypropylene clamps withstand moisture and most chemicals. They have a folding arm that closes to secure material.

Connectable Plastic Routing Clamps

Join these clamps together to line up multiple pipes, cables, or tubes side-by-side, even when they are different sizes.

Two-Line Weld-Mount
Vibration-Damping Routing Clamps

Secure two pressurized hydraulic lines with a single clamp to lessen vibration in hydraulic systems. Weld the bottom plate onto the mounting surface for a more secure connection than rail- and adhesive-mount clamps.

Strut-Mount Routing Saddles for Insulated Pipe

Clip these saddles around the outside of strut channel for a quick way to route insulated tubing and pipe. Lips on either end of the saddle protect insulation from abrasion if the pipe should move.

Stud-Mount Routing Supports

Attach these supports onto metal stud knockouts to route cable, conduit, and tubing through metal studs.
