Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance.

Collars create branches from a rectangular duct. Cut a hole in the duct and use a collar to attach standard duct. Collar with polyethylene gasket is self-sealing because the gasket has an adhesive back. The flange has 1/8" dia. mounting holes.

Rectangular Duct and Fittings
Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height. Duct and fittings have interconnecting ends that lock together with brackets.

Shims for Keyed Shafts
Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.
Shims with a tab only fit without a key—the tab sits inside the keyway on the keyed shaft.
Carbon steel shims are stronger than stainless steel shims, but shouldn’t be used in wet environments.
