Lifting and Pulling

Counterbalancers

A spring controls the tension.

Support the weight of your tool with air hose instead of a separate cable.

Manual-Return Hanging Retractors

Lift your tool until the cable retracts into the housing.

Automatic-Return Hanging Retractors

Let go of your tool and the cable pulls it back up.

Shaft-Mount Retractors

Building and Machinery Hardware

Overhead-Mount Window Balancers

Mount these balancers in the corner of a horizontal frame to suspend, lift, or lower objects that move vertically in a track such as windows, doors, and panels.

Side-Mount Window Balancers

Install these balancers on a vertical frame to suspend, lift, or lower objects that move vertically in a track such as windows, doors, and panels.

Counterbalancing Positioning Arms

Reduce hand fatigue in continuous fastening and grinding applications. Arms are counterbalanced to support the full weight of the tool as well as absorb torque.

Constant-Force Retractors

For controlled extension and retraction, these retractors provide the same amount of force no matter how far you extend them. The flexible attachment cable allows a wider range of movement than standard constant-force springs.
