Make-It-Rigid Stiffener - PRISONER (for Clejuso Mod. 12A, handcuffs optionally included)

A simple addition that changes how restraint feels.

The Make-It-Rigid stiffener is designed to connect handcuffs into a fixed position, reducing movement and creating a more defined and deliberate form of control.

This version of the Make-It-Rigid stiffener is made exclusively for the Clejuso Mod. 12A handcuffs - the wider model built for larger wrists.

The stiffener is a two-part housing that fully encloses the chain. The cuffs are laid into the lower shell, the upper shell is placed on top and secured with four stainless steel countersunk screws. Once closed, the chain disappears inside the body and the cuffs are held in a rigid, fixed position.

An integrated stainless steel anchor lug on the top face gives you a defined attachment point - for a leash, a tether or a fixed point in the room. Both end slots stay accessible for additional straps or carabiners.

The top face carries a raised PRISONER lettering with hazard striping - a clear visual statement in matching orange.

Designed and produced in our Berlin studio, with a focus on precision and reliability.
