Hard 5 block, single block with a new pulley system designed and built to organize and support the load of tires on Inverter and gearbox spearguns.
The pulley has been machined from solid from a bar of a special polymer and is characterized by a groove deep enough to ensure maximum adherence of the line inside, so as to avoid slippage.
The tires are joined to the trolley by means of three small hourglass-shaped cylinders, binding them centrally and ensuring a symmetrical and well-balanced load of the elastic with the whole structure.
The frame, made of stainless steel, is composed of two 1.5mm thick fully discharged plates, so as to reduce weight to a minimum. The axis of the pulley, of the "through" type, has been designed to guarantee the holding of any load without compromising the functioning of the structure.
The block Hard 5 can mount up to 5 rubber bands, optimizing the overall dimensions and maintaining their correct positioning. This system guarantees maximum performance and reliability.
