These Midrange Captive Bearing Traveler Cars have a stand-up toggle with "ears" that holds the mainsheet block upright off the deck. The toggle attaches low inside the car, so mainsheet loads as much as 40 off-angle don't impede the ball bearings from rolling freely. The high-strength Torlon ball bearings run on machined, Hardkote-anodized, Teflon impregnated races for smooth trimming and easing. Proper choice of purchase allows easy adjustment of the car using a single line and no winch.The side ears are used for attaching traveler control blocks directly to the stand-up toggle, without using the available car-mounted purchase configurations. This lets you choose the exact block and sheave size you require, as well as allowing for easy modifications. Use with 27 mm CB Track Available in standard and high-load versions to handle mainsheet loads on boats from 27 ft to 34 ft (8 to 10 m) Solid 6061-T aluminum body for light weight, strength, and durability Captive bearings for easy loading and maintenance Please call us if you have questions regarding gear selection for your boat
