Ronstan Nicro Snap Shackle Snatch Blocks

Ronstan Nicro Snap Shackle Snatch Blocks

Ronstan's Nicro snatch blocks are convenient solutions for temporary leads and line deflection. All have an easily operated latch mecanism and soft resilient cheeks to reduce clatter and protect gelcoat and painted surfaces. Snap shackle heads swivel through 360°, and the snap shackles are investment cast grade 15-5PH stainless. Blocks with trunnion snap shackles allow additional articulation from side to side, making it easier to get a fair lead at low angles, such as when mounted on a toe-rail. All feature a 316 stainless steel frame and load straps. Roller bearings on blocks that have them are also 316 stainless. Cam Lock versions have a simple rotating cam mechanism for positive closure and easy opening.

    Harken Snatch Blocks

    Harken Snatch Blocks

    Harken Snatch blocks feature low-friction roller/ball bearing sheaves and a unique push-button latch for one-handed operation. The opening side allows sheets to be inserted without reeving a free end through the block.

    Urethane sideplates prevent damage to decks, spars, and cabin houses. An integral bail allows blocks to hang from lifelines with shockcord. Snap shackles attach to padeyes and bails, while trunnion shackles attach to toerails and other fixtures where an ordinary snap shackle will not align with the load.

      Harken snatch blocks are offered in high-load and low-load configurations and are used on offshore boats of all sizes. Use Harken snatch blocks for genoa leads, mast base reefing blocks, protected trip buttons, changing sheets, or spinnaker sheet deflector blocks. All have 64mm (2 1/2") diameter sheaves and support line up to 16mm (5/8") diameter.

    High-Load Snatch Blocks by Harken

    High-Load Snatch Blocks by Harken

    The work horses on large yachts from Grand Prix to Megayachts. With LOUP attachments, opening sideplates and simple operation, these compact blocks are extremely versatile, allowing crew to quickly fasten them when needed. The blocks excel in static line applications that require small adjustments: tack-line leads, barberhaulers, floating athwartship blocks, Code Zero sheet blocks and sheet deflectors.

    Sideplates pivot open, making it easy to attach to an active rigged line. Harken’s Hardkote-anodized sideplates are made of 6061-T6 aluminum, housing the sheave and keeping it aligned relative to loads. The aluminum sheave has a Teflon®-impregnated ULC (Ultra-Light Composite) bearing which rides on a heat-treated 17-4 PH stainless steel inner race. Snap-fit Torlon® ball bearings handle thrust loads.

    Urethane sideplates prevent damage to decks, spars, and cabin houses. An integral bail allows blocks to hang from lifelines with shockcord. Snap shackles attach to padeyes and bails, while trunnion shackles attach to toerails and other fixtures where an ordinary snap shackle will not align with the load.

     Harken snatch blocks are offered in high-load and low-load configurations and are used on offshore boats of all sizes. Use Harken snatch blocks for genoa leads, mast base reefing blocks, protected trip buttons, changing sheets, or spinnaker sheet deflector blocks.
