The System 22 High Beam Main Sheet Track Assembly is designed for medium-sized sailboats, with a 6:1 purchase operated through cam cleats on the car and a track that is unsupported in the middle.

The kit includes:

• Main sheet car 442-149-02 with integrated cam cleats for the control line. Top-guides and fair leads enable operation remote from the car as they guide the line straight in to the cam cleats. With a continuous control line you can operate the leeward cleat and the windward cleat from the windward rail. The car is black anodised, extruded aluminium and runs on Torlon® ball bearings. It features plain bearing polymer sheaves for control lines and an AISI 316 mirror finished stainless toggle for Seldén PBB 50, BBB60, R60 and A60 blocks. The toggle and sheet block are supported by a rubber stand-up collar to improve function and to dampen vibrations.
• End controls 442-112-01. Plain bearing sheaves and an integrated becket for the control line. Rubber shock absorbers prevent damages on car and end controls. 
• 22 mm hard anodized High Beam track for M5 screws. Length 1500 mm. The track is a sliding bolt design, ideal for retrofit upgrades as you need no new holes. Use M6 bolts and Seldén's sealing washers art no 164-482. It is critical an unsupported track is mounted and secured using a minimum of three fixing bolts on either side of the unsupported length.
• High beam adaptor in composite to finish off the high beam track. 
• 12 m control line, 24-plait Polyester.
