Selecting Clamps Using Pipe, Conduit, or Tubing Trade Size

Fast-Action Bar Clamps

The clamping arm slides freely along the bar for quick, one handed positioning. Tighten the screw onto a workpiece and the arm locks in place.

Heavy Duty Fast-Action Bar Clamps

These clamps have twice the capacity of standard fast-action bar clamps.

Extra Heavy Duty Fast-Action Bar Clamps

For the most demanding jobs, these clamps have almost five times the capacity of standard fast-action bar clamps.

Vibration-Resistant Fast-Action Bar Clamps

Pull the handle to lock the jaw in place and prevent loosening caused by vibration.

Trigger-Action Bar Clamps

Press the trigger to slide the clamping arm along the bar. Release the trigger and squeeze the pistol-grip handle to lock the clamp in place.

Trigger-Action Bar Clamps/Spreaders

Press the trigger to slide the clamping arm along the bar. Release the trigger and squeeze the pistol‐grip handle to lock the clamp in place.

Fast-Action Bar Clamps/Spreaders

Each arm slides freely for quick, one-handed positioning. They lock when the screws are tightened onto a workpiece.

Reverse-Action Push Toggle Clamps

Pull the handle backward to push the plunger forward. These clamps secure when the plunger is fully extended to hold your workpiece from the side.

Heavy Duty Reverse-Action Push Toggle Clamps

A highly durable construction with hardened steel pivot pins and bushings provides a long service life.

Fast-Action C-Clamps

Press the quick‐release button and slide the screw into position to make adjustments in less time.

Bar-Style Locking Plier Clamps

Slide the upper jaw to adjust the opening size. These clamps hold larger workpieces than other locking plier clamps of similar size.

Loop Clamps

Vibration-Damping Loop Clamps

A cushion covering the clamp reduces vibration and wear from clamp edges. Clamps surround lines of pipe, tubing, and conduit completely while holding them close to the mounting surface.

Multiline Vibration-Damping Loop Clamps

Organize multiple lines of pipe, tubing, and conduit with one clamp. Wider than standard loop clamps, multiline loop clamps surround two lines of material to create a secure grip while holding the lines close to the mounting surface. A cushion covering the clamp reduces vibration and wear from clamp edges.

Snug-Fit Vibration-Damping Loop Clamps

A molded cushion reduces vibration and wear from clamp edges, plus it provides a tighter fit around material than standard vibration-damping loop clamps.

Plastic Loop Clamps

Compared to metal loop clamps, plastic loop clamps reduce wear on soft materials, such as tubing and cable. Clamps are nonconductive and noncorrosive.

Loop Clamps

These clamps completely surround single lines of pipe, tubing, and conduit while holding them close to the mounting surface.

Multiline Loop Clamps

Routing Clamps

For use with a single line, these clamps brace pipe, tubing, and conduit directly against the mounting surface.

Plastic Routing Clamps

For use with a single line, these plastic clamps reduce wear on softer materials, such as tubing and cable, and prevent corrosion caused by metal-to-metal contact.

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 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.

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.

Adhesive-Back Plastic Routing Clamps

Backed with foam adhesive tape, these clamps mount to any smooth surface—no fasteners required. They are noncorrosive, nonconductive nylon.

Vibration-Damping Routing Clamps

A rubber cushion reduces vibration and wear from clamp edges. The cushion also protects lines of pipe, tubing, and conduit from corrosion caused by metal-to-metal contact.

Strut-Mount Vibration-Damping Routing Clamps

Slide multiple clamps into existing strut channel to organize lines of pipe, tubing, and conduit without the need for drilling, welding, or using adhesive. Clamps have a plastic or rubber cushion or body to reduce vibration.
