    Barton Large Snatch Block f/Yachts Up to 40' (12.2M) - Stainless Steel Snap [90401]

    Large Snatch Block for Yachts Up to 40' (12.2M) - Stainless Steel SnapBarton Snatch Blocks give the crew the option to locate the block anywhere on deck using the stainless steel snap shackle, then locate a rope into the sheave without the need to reeve the line through. The side plate unclips to allow easy access.Manufactured using 316 stainless steel, they come with a snap shackle, snap hook, and glass-filled nylon side plates. You can also choose a stainless steel ‘D’ Shackle for ultimate strength. These are used to divert sheet lines already in use, typically the Spinnaker or Genoa, where a change of sheeting angle is required.*Important note: Snatch Blocks: When using Snatch Blocks on a toe rail, a bungee line should be attached to the becket to prevent the block 'tumbling' and causing damage by snagging.
