32 mm Track End Control - Double Control Block - w/Cam (pair) - 3/8" Max Line, 3:1 & 4:1 Purchase

These durable track ends are machined from a single piece of aluminum. The integral 40 mm Carbo Airblocks® with free-running Delrin® ball bearings allow for easy adjustment when you move the car in a strong breeze - which is when you want the traveler to work at its best. Cam-Matic® cleats provide precise cleating.


• Purchase Upgrade Kits (T32KIT and T32KIT.HL) upgrade from 1:1 to 4:1 and include: (4) blocks, (2) deadends, and fasteners

When deciding on a purchase system, expect the load on the control line to be approximately 20% of the load on the mainsheet block. For most cruising boats, this will mean designing a 4:1 (or even higher) purchase system to keep control line loads in the reasonable 30 to 45 lb range.
