These aluminum bases provide more impact protection than plastic bases. In addition to protecting the bottom of a wall from damage, they create a finished look where the wall meets the floor. They're commonly used in warehouse and manufacturing areas.

Connect ball swivels and damper linkages to an actuating motor to control ventilation dampers.

Use these closers when your door-to-door clearance is limited. They close storm doors more smoothly than standard spring closers.

To protect doors and walls, these closers have a shock-absorbing stop to damp the force of doors when they’re pushed open. Designed for frequently used doors, these 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.

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.

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

These actuators provide better control than incremental actuators because they are constantly being positioned in response to duct airflow requirements.

A molded cushion reduces vibration and wear from clamp edges, plus it provides a tighter fit around material than standard vibration-damping loop clamps.

Each hub includes a set screw, which bites into your shaft to hold the coupling in place.
