Ultra Thin Shim (Key Style)
1½” Spring Steel. This shim works most universal handcuffs. The shim slides between the ratchet and the pawl of the cuffs to quickly release the locking mechanism. Handcuffs are being manufactured with much tighter tolerances, the Ultra Thin Shims help bypass this and can also be used as a bypass tool on some combination padlocks.
Works ONLY when cuffs are single-locked.
