HARKEN 32mm Big Boat End Controls & Accessories

Carbo Ball Bearing End Controls allow the installation of 2:1 to 6:1 purchases. Designed for high-performance, free-running systems, Carbo control blocks with Delrin® ball bearings let cars adjust and release under load. Assemblies secure to track, eliminating additional holes. Tough, one-piece bases and cam arms are machined from single pieces of aluminum. Compact, low-friction block components combined with Cam-Matic cleats keep weight minimal.

High Load Controls are designed for offshore boats with mainsails over 400 sq. ft., and allow 2:1 to 6:1 purchases. The 3173 and 3174 controls use 57mm Black Magic® Big Boat ball/roller sheaves and high-load aluminum sideplates to handle shock loading.

ESP Sleeve-Bearing End Controls are value-oriented options for the installation of 2:1 to 5:1 systems. Designed for strength and durability, controls feature sleeve bearing sheaves with sideload ball bearings. Use E3250HB double-sheave end controls for cabintop travelers with cars using 3:1 or 4:1 purchases. Modular design allows you to increase the purchase of your system using Purchase Upgrade Kits.
