The Lewmar 90 mm Synchro Fiddle Block with Swivel, Becket and Cam Cleat, model number 2992-9039, is a high-performance sailing block that offers speed, efficiency and superior handling.
Here are some of the details and specs of this product:
• fiddle design, which means it has two sheaves of different diameters on the same axle. This allows for a smaller and lighter block that can handle higher loads and reduce friction.
• swivel head, which allows the block to rotate freely in any direction. The swivel head also has asliding mechanism that can lock the block in two fixed positions (0° or 90° to the sheave axle) or allow full 360° rotation. The fixed positions allow for 30 degrees of rotational freedom, which helps to ensure that the block aligns with the system.
• becket, which is a loop or eye at the base of the block that can be used to attach another line or block. This can create a more complex and efficient pulley system.
• cam cleat, which is a device that can grip and release a line quickly and easily. The cam cleat has two spring-loaded jaws that clamp the line when it is pulled in one direction and release it when it is pulled in the opposite direction. The cam cleat can be used to adjust the tension of the line or secure it in place.
• stainless steel strap for improved strength and longer service life. The strap also prevents the line from wedging between the cheeks of the block.
• free-spin bearing and a self-aligning head that reduce friction and increase efficiency by up to 40% over budget blocks on mainsheet systems. The bearing and the head are synchronized with the movement of the rope, providing an easier and smoother transfer of power from deck to sail and less wear on the rope.
