The Fast-lock pulley system special feature is the simple rope-operated locking mechanism which prevents the rope going backwards. This allows you to take the load in a series of purchases as required. The lock is automatically engaged as the rope is pulled. The componentary is all stainless steel with the pulleys cut from hi-density nylon. The rope is 7.2m of thick and soft 10mm-diameter nylon. Easy on the hands. Suitable for lifts up to 200kg.
