STEERING BLOCKS
ALUMINIUM /ertalyte or CARBON / ertalyte or CARBON/ carbon
All specially designed for 2 way configurations,
JP3 steering blocks finally offer NO PLAY systems.
JP3 steering blocks are designed to compliment the other steering components to provide a complete system.
All blocks feature :
• Ertalyte sheaves that provide a wear resistant surface that is suitable for either wire or vectran.
• Sealed stainless steel deep groove bearings to ensure low friction, smooth quiet running.
• Blocks are available in 4 sizes.
• Blocks are available in 3 housing styles to suit all installation details.
• Aluminium bodies are anodised in our in-house anodisation plant to ensure quality and prevent corrosive action.
BLOCK STYLES
JP3 blocks are available with 5 styles:
Simple Blocks.
SB & DB
The simple blocks are a fixed block and feature sheaves supported between 2 aluminium angle side plates that are bolted to a flat surface and the cables exit a 90º to that surface.
Available as both a single 'SB' and double blocks. 'DB'.
Sizes, Ø100, Ø120, Ø150 & Ø180mm
FOOT BLOCKS
SFB & DFB –
The foot blocks are used where steering cables are running parallel to a flat surface and need to change direction. The foot blocks are designed to fasten straight to the flat surface through the stainless steel base.
Available as both a single and double block.
Sizes, Ø100, Ø120, Ø150 & Ø180mm
Articulating blocks
Type AFB
The articulating block is used where the steering cables will be at an angle to the block mounting surfaces.
Available as only a single block
Sizes, Ø100, Ø120, Ø150 & Ø180mm
CARBON STEERING BLOCKS
JP3 creates a new range of carbon blocks specially designed for steering systems fitted in racing carbon hulls. Blocks are clean and bonding the cheeks is very simple, laminating over the end and wedges , it makes the system very STRONG but still LIGHTWEIGHT.
*can be sold separately
JP3 block bearing allows loads, equally in and out.
(This is too often not the case with on deck sheaves originally made for runners or halyards , efficient one way, but creating friction when reversing.)
