These retractable cable blocks extend to 10m, 15m and 30m lengths and come in a tough, robust plastic casing.
Swivel hook attachment reduces twist problems while in use and helps the user when they need to turn around, etc. The hook also has a load indicator which shows green when safe to use and red when unit has had a substantial loading and should be inspected.
Unique to this unit is a spring at the base of the cable to stop it locking permanently if accidentally fully retracted. The user can simply push in against the spring to release the cable again, unlike other models which require the entire unit to be disassembled.
