This latch kit works with our line of Pewag Grade 80 Alloy Swivel Hooks. While we only carry the alloy version of these hooks, this latch kit will work with the carbon version as well (see PDF for details). This latch kit features a heavy-duty design, and ships with the latch itself, spring, pin and bolt. Installation is simple and requires only common tools (screwdriver, pliers and/or wrench).
