Tough and tiny soft-attach block is lighter than a small standard metal shackle. At only 7.2 grams, it is 20 percent lighter and 10 percent smaller than comparably-sized blocks. It ties, splices or lashes just about anywhere, including tight spaces. Excellent complement to T2 Blocks on skiffs, dinghies and beach cats. Stainless ball bearings in captive races spin the sheave on an integrated 316 stainless steel inner race, providing optimal strength-to-weight. Soft attachment allows the block to articulate and align with loads. A length of 1/16" line is included, which routes through the block head and sheave, reducing loads on the sideplates. Maximum line size is 3/16" (5mm).
