SeaSure 01.01 25 mm Brass Sheave Single Block with Shackle
SeaSure 01.01 is a 25 mm single block designed for medium- to high-load applications with slow-running ropes. Compared with the standard Mini block range, this block is intended to handle higher loads.
The block uses a brass sheave together with stainless steel side plates. SeaSure states that the stainless steel side plates help protect highly abrasive ropes from cutting in, while the brass sheave is suited to slow-running rope applications.
The integrated shackle allows the block to be moved easily or attached to a suitable anchor point. The block has a maximum breaking strength (MBS) of 950 kg and a safe working load (SWL) of 475 kg.
The supplied catalogue data specifies a maximum rope diameter of 5 mm, while SeaSure's product page lists a maximum rope diameter of 4 mm.
