Ronstan's SA Snatch Block delivers the highest load ratings for its sheave diameter in the keelboat block range. This high-load single-sheave snatch block features a soft attachment design with no Dyneema® loop included, giving you the flexibility to create your own lashing. Anodised aluminium cheek plates and sheave, self-lubricating composite bearings, and a duplex stainless steel hub make it suitable for both static and dynamic load applications.

Cheek plates rotate open and close with a spring-loaded ball lock for secure, reliable closure and easy line loading and removal.

Note: MWL and BL ratings are for the block only and do not include the soft attachment. Consideration must be given when selecting your attachment option as it may not be equivalent to the block MWL and BL. The complete block with SK99 Dyneema® soft shackle is available as RF47109. The soft shackle is also available separately as RF7008-09.
