PULLEY (P/N s394) - New Surplus

The s394 is an aircraft control cable pulley designed to route and support flight-control cables while reducing friction and maintaining proper bend radius. This pulley guides cables through directional changes in control system runs, preventing excessive stress on cable jackets and supporting smooth control surface operation. Typically constructed from aluminum or steel with a grooved wheel, the s394 mounts in approved brackets using standard AN or MS hardware.

Installation requires verification of cable size compatibility and bracket positioning per your aircraft's Illustrated Parts Catalog to ensure proper alignment and cable support.
