Hexa-Cat Bases These bases are used to build powerful mainsheet systems and tackles to grip loaded sheets. The Hexa-Cat’s upper and lower blocks swivel independently so the cam block pivots to face the trimmer. Ratcets feature Hardkote-anodized Teflon®-impregnated eight-sided sheaves machined from solid aluminum for strength and corrosion resistance. Free-rolling Delrin®ball bearings, sheave and sideplates UV-stabilized with carbon-black additive for maximum protection. High-strength stainless steel straps reinforce blocks. Combine the 193 Little Hexa-Cat base with Big Bullet blocks or the 170 Hexa-Cat base with 2.25 in blocks for purchases from 5:1 to 8:1. Use for: Mainsheet systems Vangs
