Nonsparking Wedges

Aluminum Bronze

These wedges are made of nonsparking materials. They're good for making quick height adjustments. Use in pairs for parallel adjustment. Also known as fox and flange wedges.

Warning: Do not use these tools in direct contact with acetylene.

Aluminum Bronze—Aluminum bronze wedges are Factory Mutual approved, nonmagnetic, and corrosion resistant. They satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Heavy Duty Tapered Shims

Image of Product. Front orientation. Contains Annotated. Shims. Sold Individually, Heavy Duty, Taper.

Align heavy machinery. Originally designed for leveling leaf springs on pick-up trucks, these aluminum shims are stronger than plastic and wood shims. Wedge them under your machine’s feet until you reach the desired level—no need to stack multiple flat shims. Ridges grip surfaces to prevent these shims from sliding, while also facilitating small adjustments. To secure them in place, drive a screw through the center mounting hole.

Dual-Clamping Fixture Clamps

Set one of these clamps between two workpieces in a fixture and tighten the screw to push the clamp's sides out for a secure hold. The minimal contact leaves more of the workpieces free for machining.

Machinable Dual-Clamping Fixture Clamps

Machine these fixture clamps to match the contours of your workpieces for a stronger grip. Place the clamp between the two workpieces in a fixture and tighten the screw to extend the sides of the clamp, creating a secure hold against both workpieces. Minimal contact with the workpiece leaves more of its surface accessible for machining. Each clamp comes with a locking plate to keep the clamp rigid while machining it to fit your application.

Clog-Resistant Polishing Stones for Steel

No need to stop and clean these stones as you polish—they’re filled with oil to keep debris from getting stuck in the pores. Use a holder to polish by hand or with a power tool (both sold separately). You’ll also need a water-soluble or oil-based lubricant to wash away debris and reduce friction and heat on your workpiece.

Straight Wedge

Aluminum Oxide Abrasive—Aluminum oxide stones, also known as India stones, scrape away material slowly to give you more control over how much material you take off. They are good for the final stage of polishing.

Tank Car Pry Lever Bars

Safely open manway covers on tank cars. These pry bars have a u-shaped end that grips the cover’s handle, giving you leverage to break the suction caused by pressure differences between the inside and outside of the tank. They’re 60" (5 ft.) long, so you can stand upright while using them to avoid fumes as the cover opens. Made of aluminum, these bars won’t spark, making them safe to use near flammable vapors and combustible residues.

Wheel Chocks


Style 7	Style 8

Keep wheels stationary while loading, unloading, and servicing vehicles. Chocks for wheel diameters 30" and larger are typically used for commercial vehicles, including semi-trucks and tractors. Chocks for wheel diameters under 30" are for use on small cars, trucks, and vans.

Chocks with a rope, carrying handle, or U-bolt handle give you a gripping point for easy carrying.

Chocks with a hole, an anchor plate with hole, an eyebolt, or a chain let you connect two chocks or can be secured to prevent theft.

Not Reversible


Style 7	Style 8

Aluminum—Aluminum chocks are lightweight for easy handling.

Style 8—Style 8 have a flag that inserts and locks on either side to indicate that chock is in use.

Hollow Middle—Chocks with a hollow middle are lighter in weight than solid chocks.

Wheel Chocks with Extended-Length Handle

Aluminum with Flag

Quickly and safely secure a vehicle’s wheels without bending down. The handle makes these wheel chocks ergonomic and reduces the risk of injury if your vehicle moves during installation. Use them during loading, unloading, and servicing vehicles.

Aluminum—Aluminum chocks are lightweight for easy handling. They also resist corrosion, so they’re suited for outdoor use.

Hollow Middle—Chocks with a hollow middle are lighter and easier to transport than solid chocks.

Flag—Chocks with a flag increase visibility for safety.
