Power Transmission

Corrosion-Resistant Eyelet
Mounting Brackets for Gas Springs

Made from stainless steel for excellent corrosion resistance in damp environments.

Corrosion-Resistant Heavy Duty Eyelet
Mounting Brackets for Gas Springs

Made from stainless steel for excellent corrosion resistance in damp environments.

Corrosion-Resistant Compression Springs

These springs are more corrosion resistant than standard compression springs.

Corrosion-Resistant Compression Spring Stock

Made of stainless steel, these springs are more corrosion resistant than steel compression springs.

Corrosion-Resistant Precision Compression Springs

Made of stainless steel, these springs are more corrosion resistant than steel compression springs.

Made-to-Order Compression Springs

If you're designing something unique or can't find the exact size spring you need, we'll get it for you.

Confined-Space Conical Compression Springs

Install these springs in tight spots. When pushed together, the coils nest within each other.

High-Misalignment Vibration-Damping
Precision Flexible Shaft Couplings

Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment.

Building and Machinery Hardware

Extreme-Temperature Vibration-Damping
Mounts with Counterbored Unthreaded Hole

Install these mounts with a socket head cap screw—the counterbored hole ensures the screw sits flush with or below the top of the mount.

Extreme-Temperature Vibration-Damping
Mounts with Unthreaded Hole

Made of tightly layered stainless steel mesh, these mounts withstand temperatures up to 500° F.

Horizontal-Force Bolt-Down Vibration-Damping
Mounts with Unthreaded Hole

Isolate vibration and noise from oscillating equipment like fans and tumblers that create horizontal (shear) force.

Extreme-Temperature Vibration-Damping Pads

Made of tightly layered stainless steel mesh, these pads withstand a wide temperature range from -120° to 500° F.

Door Stops for Sliding Doors

Keep sliding doors and panels from damaging walls and door frames.

Lockset Bumpers

Protect door knobs and other hardware from damage caused by carts, dollies, and other equipment.

Metal Corner Guards

These metal guards provide more impact protection than plastic guards. Commonly used in warehouse and manufacturing areas, they protect corners on walls and other surfaces from impact.

Door Kick Plates

Also known as door plates, armor plates, and mop plates, kick plates protect the base of a door from damage caused by foot traffic and equipment.

Heating, Venting, and Air Conditioning

Quick-Disconnect Duct and Fittings

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

Enclosure Intake and Exhaust Hoods

These hoods keep your enclosure watertight, even around intake and exhaust cutouts.

Routing and Suspending

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.

Rails for Rail-Mount Vibration-Damping Routing Clamps

Bolt or weld these rails to the mounting surface, then attach clamps with a rail nut.

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.

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.

Vibration-Damping U-Bolts

Reduce vibration and noise in your lines—a plastic cushion tightly grips pipe, tubing, and conduit to prevent movement. Nylon-insert locknuts grip the thread to resist loosening.

Rubber-Cushioned U-Bolts

A durable rubber cushion and mounting plate prevent corrosion and wear caused by metal-to-metal contact. The mounting plate is removable, so the U-bolts can be installed onto an existing line without needing to dissemble it.

Washdown Vibration-Damping
Threaded-Rod-Mount Clamping Hangers

These hangers provide maximum corrosion resistance in wet environments and stand up to frequent washdowns with harsh cleaners and sanitizers. Rounded edges, polished surfaces, and acorn or hex nuts that conceal threads reduce the number of places for bacteria to grow and make them easier to clean.

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.

Weld-Mount Clamping Hangers

For a strong, secure connection, mount these hangers by welding them to a rod.

Control of Liquids, Gases, and Solids

High-Temperature All-Metal
Expansion Joints with Flanged Ends

These all-metal expansion joints can handle high temperatures up to 800° F.

Expansion Joints with Butt-Weld Ends

These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant permanent connection.

Gauge Vibration Dampers

Also known as snubbers, these reduce the flow of fluids into your pressure gauge to damper vibration, pulsation, and pressure spikes.
