Ultra Thin Key Style Shim 2-Pack
1½” Spring Steel, Shim works most universal handcuffs. The shim slides between the ratchet and the teeth of the cuffs to quickly release the locking mechanism. Works ONLY when cuffs are single-locked.
Newer 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.
