Alan Manufacturing's Cable Damper Systems are designed to be used when a motorized system is not practical. The flexible cable and wire can be routed around electrical conduit, piping and other obstructions, without fear of binding or catching. ALAN Rotary-to-linear (rack & pinion) mechanical actuator assembly securely holds the damper in position for precise dependable settings. Cables can be connected together if a greater length is required.
