Hales single deck mounted block.

Hales single block with shackle

Hales double deck mounted block.

Plastic through deck sheet lead comes as two pieces with mounting screws and 100mm 2mm ID PTFE tube. 

Ideal for allowing your sheets to pass through the deck, simply drill a hole in the deck for the tube to pass through and holes for the mounting screws. One piece mounts from underneath the deck (with nuts in the body of the fitting) and place the second piece on top and screw the mounting screws in. It's easy to mount and with no fiddly tricky placing of nuts on screws under the deck.

A perfect solution for those with Vickers boats looking to remove the aft mounted snorkel.

Through Deck Block

The SAILSetc Through Deck Block is a compact, low-friction solution for routing control lines cleanly through the deck of your radio yacht while minimising water ingress. The line passes through the block with minimal friction while helping keep water out of the hull.

Developed from SAILSetc's proven through-deck block designs, this latest version offers improved sealing and reliability for modern Dyneema rigging systems. 

Suitable for use with Dyneema lines up to 100kg breaking strain, making it ideal for IOM, Marblehead, Ten Rater and other high-performance radio yachts.
