SeaSure 01.08 25 mm Brass Sheave Spar Mounted High-Load Block
SeaSure 01.08 is a 25 mm spar mounted block designed to carry higher loads than standard Mini blocks. It is intended for medium- to high-load applications with slow-running ropes and is commonly used with Dyneema, Spectra and Kevlar lines.
The block uses a brass sheave together with stainless steel side plates. SeaSure states that the stainless steel side plates help prevent highly abrasive ropes from cutting into the block structure.
The spar mounted configuration is designed for direct installation using 5 mm bolts or rivets, providing a fixed rope-routing point on the mounting surface.
The SeaSure 01.08 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 lists a maximum rope diameter of 4 mm.
