To provide corrosion resistance in wet environments, this framing is galvanized.

Often used on large freezer and cold-storage doors, these closers are designed for doors that weigh 200 lbs. or more.

A built-in stop prevents doors from opening too far—good when wall- or floor-stops can’t be used. Designed for frequently used doors, these closers last twice as long as standard door closers. They can replace Yale, Dorma, Falcon, Stanley, Parker, and Cal-Royal models with the same mounting hole pattern.

Pull a chain to manually open overhead doors.

The sealed ball bearings will never need additional lubrication.

Load material between the two halves of the ring and adjust the side bolts for a tighter fit than standard threaded-rod-mount clamping hangers.

Attach these clamps to the flange of an beam, then hang a threaded rod from the threaded hole.

For centered load distribution, these clamps grip both sides of the beam and hang threaded rod from the middle.

Join two beams in a straight line.

Combine fast-threading components to build a clamping assembly.

Build a custom clamping system for holding lightweight objects such as beakers and laboratory equipment.

Add components such as clamps, brackets, stops, rests, mounting plates, fixturing squares, risers, and V-blocks to build fixtures for welding and assembly.

Ensure accurate right angles and hold workpieces and fixtures perpendicular to a machine table by securing them to these plates with clamps.

Build fixtures on multiple sides of these squares.

These plates have three T-slots for use with T-slot nuts, bolts, and setup studs.

Rotate your work 360°. These tables can be mounted horizontally or vertically.

These snaps have an eye that rotates for easy positioning.

Make a removable loop without specialty tools for use in noncritical applications, such as fencing. Also known as tiller clamps.
