The 3M DBI SALA 5 lb. Tool Retractor features a lockable line that can retract when not in use to minimizing tangling and tripping hazards. A strong Dyneema retracting line secures your tools that weigh up to 5 lbs. The line can extend your reach up to 50 inches while your working and keep your tools out of the way when you finish a task. Both ends of the Tool Retractor feature self-locking aluminum carabiners to help you prevent an accidental disconnection or carabiner rollout.
