Barton Marine Size 7 Plain-Bearing Stand-Up Block

The Barton Marine Size 7 Plain-Bearing Stand-Up Block is built for sail-control systems that need a strong, compact change of line direction. Barton Marine's plain-bearing block construction uses molded sheaves and corrosion-resistant internal hardware to keep the line running smoothly under load. Through-bolted and riveted construction adds security at the side plates, while the specified swivel, becket, upright, or stand-up configuration suits the intended rigging layout. The block is sized for cruising and racing applications where dependable load handling matters more than unnecessary complexity.

This range of high-load cruiser bocks is of rugged construction, featuring high-quality injection molded side plates with all load-carrying components from 316-grade stainless steel. Side plates are through-bolted and riveted for added strength and security. Note: break loads where break and safe working loads are stated, it is assumed that all sheaves are evenly loaded as in a purchase tackle Uneven loading, or loading of one sheave in a double or triple block, will severely affect the strength quoted.
