Use on clamps with open arms to keep the holding screw in place.

Connect extra-support quick-clamp fittings for a fast and easy way to access your line.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Repair pinholes, punctures, and cracks in low-pressure systems with these clamps. Insert tubing into the clamp and tighten the bolts to create a secure seal.

Use these fittings to make leak-resistant connections without threading or soldering. Slide them over tubing and turn the end nuts to compress the gasket.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

Use in high-pressure applications up to 500 psi.

The grooved ends on these flanges connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. Flanges have excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances. They are also known as Victaulic flanges.

Connect these fittings to standard-wall plastic pipe for use in low- to medium-pressure applications up to 750 psi.They are the industry standard for residential and commercial plumbing and water supply applications.

Use these clamps to connect easy-access UV-resistant polypropylene pipe fittings to pipe. The clamp-together design allows you to access your line for routine maintenance.

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

For repetitive workholding, mount these clamps to T-slotted framing to hold and release parts.

Thick construction makes this framing strong and sturdy.

Stronger than plastic and aluminum, this is the lightest weight framing we offer. It has good resistance to chemicals and salt water.

Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.

Pull the lever to slide the clamping arm along the bar; release to lock in place.

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

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

All adjustments can be made from one end, allowing clamping in tight spaces.

Also known as J-clamps, these provide additional clearance to reach around obstructions and clamp workpieces in recessed areas.

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

Clamp much farther in from the edge of the workpiece than with standard bar clamps.

The large, flat jaws remain parallel when clamping to apply even pressure without denting or marring the workpiece. Pull the handle to lock or release the clamping arm.

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

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

Use the power of hydraulic fluid to quickly, consistently, and repeatedly clamp and release parts with a greater clamping force than air-powered hold-down fixture clamps.

Plastic clamping surfaces prevent damage to material.

Apply pressure to the side of a workpiece as well as the top and bottom.

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

All components of these clamps are made of aluminum-bronze that is Factory Mutual approved. They satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

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

Turn the handle to tighten these multipurpose tools for strong clamping in nearly any application.

With five times the capacity of standard C-clamps, these are the highest capacity clamps we offer.

These clamps have twice the capacity of standard C-clamps.

Mount these clamps to a bench top or other surface to keep workpieces in place.

Reduce the chance of getting pinched when unclamping. These clamps have more space between the handle and the arm than other low-profile toggle clamps.

Mount these clamps below a surface.

Attach one of these nonmarring rubber or plastic tips to prevent a metal holding screw from damaging workpiece surfaces.

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

The handle locks in a horizontal position for more clearance above the clamp than standard hold-down toggle clamps.

Hold workpieces of different thicknesses without adjustment.

The matching jaws are ground flat for a firm grip and even pressure when clamping smooth surfaces.

Grip all four corners of a rectangular workpiece.

Position workpieces at any angle from 0° to 180°.

With five times the capacity of standard corner clamps, these secure two workpieces at a 90° angle.

Secure your workpiece from the side by fully extending the plunger, and push a lever to lock the handle in place.

The handle can be rotated 125° for easier access or extra clearance above the clamp.

Use for repetitive clamping and in production environments or hard-to-reach locations.

Moving parts are sealed to prevent dirt and dust from clogging the clamp.

Push or pull the plunger to hold your workpiece from the side.

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

Attached to an arm you can flex into position, these clamps hold objects such as a flashlight, tool, or instructions.

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

Clamp thin sheet material together without drilling holes. These clamps open with special pliers and spring closed when the pliers are released.

Hold large workpieces with a standard-size clamp. Slide the jaws to adjust the opening size.

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

Set includes four plier clamps and one pair of locking pliers.

Set includes 12 clamps and the installation pliers required for positioning and removal.
