Made entirely of fiberglass, these clamps won’t transmit electricity and are chemical resistant. They're often used around electrical equipment as well as in plating and anodizing applications.

Three-Way C-Clamps

Three screws apply pressure to three sides of a workpiece.

Narrow-Body C-Clamps

The clamp body is extra-slim to fit into narrow openings.

Low-Profile C-Clamps

With no handle or protruding screw, these clamps can fit into tight spaces.

Extended-Reach C-Clamps

Clamp farther in from the edge of a workpiece than with other C‐clamps.

C-Style Toggle Clamps

For repetitive clamping, turn the holding screw to adjust the opening size one time, and then use the handle to secure and release workpieces.

Swiveling Pads for C-Clamps

Replace a fixed clamping surface with a swiveling pad that compensates for uneven workpieces.

Locking Plier Clamps

Turn the knob to adjust the opening size.

Self-Adjusting Locking Plier Clamps

Squeeze the handles and the jaws will automatically adjust to fit your workpiece.

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.

Portable Bench-Top Locking Plier Clamps

A removable, heavy duty steel base plate provides a flat, durable clamping surface. Carry it where needed or mount the base plate to your workbench.

Bench-Mount Locking Plier Clamps

Mount to the top of your workbench.

Right-Angle Locking Plier Clamps for Sheets

Angled jaws clamp sheets, bars, and U-channels at 90°.

Locking Plier Clamps for Sheets

Press the lever down to lock these clamps, which fit in tight spaces and hold thin materials.

Locking Plier Spreaders

The jaws on these tools apply outward pressure for use as a spreader.

Latch-Style Clamps

Heavy Duty Latch-Style Toggle Clamps

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

Latch-Style Toggle Clamps with Locking Handle

Push the lever to lock the handle and prevent accidental opening.

Latch-Style Toggle Clamps

Fit the draw arm over a latch plate and pull the handle to clamp.

Right-Angle Latch-Style Toggle
Clamps with Locking Handle

Push the lever to lock the handle and prevent accidental opening.

Right-Angle Latch-Style Toggle Clamps

Mount the clamp on a lid and the latch plate on the side of a container.

Adjustable-Angle Handscrew Clamps

Each jaw can be positioned at an angle to hold round, angled, and odd-shaped material.

Lifting and Pulling

Vertical-Lift with 180° Flip Plate-Lifting Clamps

Nonmarring Vertical-Lift with
180° Flip Plate-Lifting Clamps

Pads on these clamps prevent the grip from biting into the load.

Vertical-Lift Plate-Lifting Clamps

Use these clamps to raise a metal plate straight up from its original vertical position.

Nonmarring Vertical-Lift Plate-Lifting Clamps

Pads on these clamps prevent the grip from biting into the load.

Horizontal-Lift Plate-Lifting Clamps

Use in pairs with a two-leg sling to transfer metal plates in a horizontal position. Unlike other plate-lifting clamps, these can pick up multiple plates at the same time.

Vertical-Lift with 90° Tilt Plate-Lifting Clamps

Clamps can take a metal plate that is stacked horizontally and tilt it up 90° to lift vertically. After lifting, clamps can place the plate back down in the original position (plate can not be flipped over).

Beam-Lifting Tongs

These tongs firmly grab flat and tapered beams.

Hand-Held Vertical-Lift Plate-Lifting Clamps

Lift metal plates by hand by gripping the edge.

Beam Clamps

Beam Clamps with Tie Wire Hanger

Attach these light duty hangers to beams and other structural elements. They include a stiff wire for supporting ceilings, lighting fixtures, and other lightweight material.

Angle Iron Clamps for Threaded Rod

A secure way to hang threaded rod from a pair of angles, such as those used in ceiling joists, without the need to drill or weld. These clamps are commonly used to suspend HVAC, conveyor, and other overhead systems.

Beam Clamps for Hooks and Hangers

Clamp to both sides of a beam to add an anchor point for hoists and other overhead equipment.

Center-Mount Beam Clamps for Threaded Rod

For centered load distribution, these clamps grip both sides of the beam and hang threaded rod from the middle.

Perpendicular Beam-to-Beam Clamps

Add a crossbeam for hanging lifting equipment, creating overhead conveyor systems, and supporting structural applications.

Parallel Beam-to-Beam Clamps

Join two beams in a straight line.

Press-Fit Beam Clamps for Threaded Rod

A toothed clip secures these clamps to the beam—no fasteners required.

Angled Beam Clamps for Threaded Rod

Also known as purlin clamps, these clamps are shaped to fit around beams that have a 45° or 90° lip.

Sloped Beam Clamps for Threaded Rod
