Navtec Integral Hydraulic Backstay Adjuster

Navtec Integral Hydraulic Backstay Adjuster

These Series 8 adjusters incorporate several key design improvements over past series. The pressure gauge is positioned prominently, enabling fast, accurate readings of tension values. A longer pump handle produces a faster pumping motion and more tension per stroke. These improvements demand greater performance out of modern masts. The feed tube is seated in the contour of the cylinder, resulting in a secure design and an integrated look. Use of the specifically-designed integral Navtec toggle is strongly recommended. Wire diameter is based on 1 x 19. Step-by-step instructions make installation simple and painless. When installing a hydraulic backstay for the first time, remove the backstay and send it to APS to be shortened, or we can supply you with a Norseman mechanical fitting for you to do all the work onsight.
