The RF35109HL can handle a maximum line size of 5/16″(8mm) and is rated to 550kgs 1,210lbs (550kg.) Maximum Working Load and 3,630lbs (1,650kg) Breaking Load. The Breaking Load is dependent on the strength of the lashing through the central hub. The hub can also double as a becket take off point for multi purchase systems.
Such a high load rating is unique for a block of this size. At just 42 grams (1.5oz) its impressive strength-to-weight ratio is a result of clever design and the selection of the right materials, such as glass fiber reinforced nylon cheeks, a high-grade stainless-steel sheave, ball race and balls.
Perfectly matched to todays high strength fiber ropes this pulley is the perfect solution for a number of application from entertainment venues to home projects.
