Protractors

Set bevels and measure angles with everything from pocket-size to long-arm protractors

Levels

Ensure surfaces are completely horizontal or vertical

Raw Materials

Plastic

A lightweight alternative to metal and glass

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Fiberglass

A lightweight alternative to metal and wood widely used in electrical and structural applications

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Aramid

Strong, lightweight, and an excellent thermal insulator; also known as Nomex

Aluminum

Lightweight, easy to machine, and corrosion resistant—all with material certificates for traceability

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering
