Adjustable Dampers

Ameritool’s Adjustable Dampers are self-contained, maintenance free units that are 100% American made. Ameritool dampers are durable and feature damping on compression or extension. The travel speed can be easily adjusted and remains constant throughout the stroke. The single direction version is controllable in one direction only, with the free flow in the opposite direction. 

Adjustment is easily achieved by extending out fully and turning the rod until the desired speed is achieved. 

These dependable units offer long life cycle performance and are available for QUICK DELIVERY.
