THIS LISTING IS FOR A HARKEN/LEWMAR SYNCHRO 50MM 4:1 BLOCK AND TACKLE, MAINSHEET SYSTEM, BOOM VANG OR DAVIT HOIST. THIS SETUP IS COMPRISED OF A NEW LEWMAR SYNCHRO 50MM FIDDLE BLOCK WITH CAM CLEAT, BECKET AND SWIVEL SHACKLE, WITH A LOWER HARKEN DOUBLE BULLET BLOCK WITH SWIVEL SHACKLE. IT COMES WITH 25 FEET OF NEW 5/16 POLYESTER DOUBLE BRAID LINE. 50mm Synchro Fiddle Block with Becket and Cam. 3/8 Inch or 10 mm.A unique block that is synchronized with running rigging systems. The 50mm fiddle block with cam is ideal for mainsheet systems, boom vangs and backstay systems. Cam cleat position can be adjusted to make cleating and un-cleating the line easier. The medium sheave diameter works well with up to 3/8 lines. Synchro blocks combine geometry, sheave ratios and a unique Free Spin bearing to deliver performance thats comparable to ball and roller bearing blocks used in racingbut at a more affordable price. Designed to optimize the relationship between block and line, these blocks have self-aligning features to maximize efficiency and reduce wear to both line and block. An innovative sliding mechanism controls shackle post swivel. With the flick of a switch select between full 360° free rotation or one of two fixed settings (0° or 90° to sheave axle).
Both fixed positions provide 30° of rotational float to allow the block to self-align to the system. Synchro blocks use a larger sheave that features the Free Spin bearing.
The bigger diameter sheave prevents distortion and reduces line wear while the Free-Spin bearing handles higher static loads. A stainless steel shackle post and framework supports the glass fiber reinforced cheeks to increase block strength while minimizing overall weight. The molded cheeks guide the line and prevent wedging. Designed to be synchronized with your boats running rigging systems, Lewmar Synchro blocks are an ideal choice for the sailor looking to get more for less: racing features at a cruising price. Plain bearing block with ball bearing like performance.
Highly efficient free-spin bearing reduces drag. Self-aligning head allows 30° of float (in locked setting) to reduce wear on line. Stainless steel strap for added strength and durability.Adjustable swivel settings: full rotation, parallel with the pin and perpendicular with the pin. Stiff cheeks guide line to prevent wedging.
