Hoist Trolleys
Transport hook-mount hoists along a beam.
Style B is rated for metric tons.
Trolleys with screw adjustment can be adjusted to fit your beam more quickly than trolleys that use spacing washers.
Warning: Never use to lift people or items over people.

Parallel Beam-to-Beam Clamps
Join two beams in a straight line without drilling or welding. The bolt can be removed to insert threaded rod.
Zinc-plated iron clamps have mild corrosion resistance. Galvanized iron clamps have better corrosion resistance than zinc-plated iron clamps.

Beam Clamps for Threaded Rod
Attach these clamps to the flange of a beam, then hang a threaded rod from the threaded hole.
Styles D, E, and H have a threaded hole on the back for supporting a hanger or routing ring.
Zinc-plated iron clamps have mild corrosion resistance.

Metric Leveling Washers for I-Beams
Commonly called beveled washers, these metric washers are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
Zinc-plated steel washers are coated for corrosion resistance in wet environments.
Hot-dipped galvanized steel washers are ten times more corrosion resistant than zinc-plated washers.
18-8 stainless steel washers are the most corrosion-resistant option.

Leveling Washers for U-Channels
Tapered to fit in a U-channel, these washers create a parallel bearing surface. They have a zinc-plated finish, so they resist corrosion in wet environments.
