Ronstan RF6741 Trunnion Snatch Block 1-3/4" Aluminum Alloy Sheave

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.

The RF6741 is a Ronstan Special Purpose Snatch Block manufactured with roller bearings that give it a high 2,805 pound working load. 

A standard snap shackle head allows a block to swivel through 360°, but a Trunnion snap shackle provides the same swivel action and offers additional articulation from side to side.

Soft resilient cheeks reduce clatter and protect gel coat and painted surfaces.

Attachment point provided for shock cord hanger.
