Snatch Block with Trunnion Head - 80mm

Stainless Steel Sheave - Roller Bearings

Snatch blocks are a tough and reliable solution for temporary leads and line deflection. Simple and quick to deploy, they can be easily opened when the load is released. Soft, resilient cheeks reduce clatter and protect gelcoat and painted surfaces.

Grade 316 stainless steel sheaves running on needle roller bearings deliver low-friction performance and a long service life. An extra wide stainless steel frame extends to the full diameter of the sheave to prevent lines from becoming jammed between the sheave and cheeks. Sheaves are removable for easy maintenance and can be used with rope or wire. An attachment point is provided for a shock cord retainer to hang the block from the lifelines. The trunnion snap shackle svivels through 360 degrees and offers additional articulation from side to side.
