This adjusting car replaces separate blocks and a connecting member. Tandem sheaves eliminate severe flexing of the backstay, providing a neat and thoroughly functional fitting. Equipped with aluminum sheaves, maximum wire diameter is 3/8″.
Note: For maximum car release, use a 1.5 to 1 ratio between backstay base width and car height. Example: If backstay width is 5″-car height should not exceed 7 1/2′ to 8′ in height off deck. Higher ratios may require manual release with aid of boat hook, etc.
