This high quality stainless steel twist shackle with shake proof pin is manufactured here in the UK.

Information about the Shake Proof Pin

The shake proof shackle has both heads threaded. The pin will not fall out, but may still be unscrewed from the partially threaded second head.

The shake proof pin incorporates an innovative polyurethane ring which enhances the fit of the shackle pin. Once in position the shackle pin will not vibrate loose.

The shake proof shackle incorporates the Smart-Lock pin. This pin benefits from a unique locking mechanism. When the ring is threaded into the shackle body the ring acts like a viscous liquid and binds itself to the internal threads in the shackle head.

After a short period of time the pin is locked into position. A sharp turn by hand or use of a shackle key will release the ring and allow the pin to be unscrewed very easily. The pin can be re-used without deterioration.
