Replacement key for steel handcuffs HM-01 / HM-03 by ESP. Compatible with HM-01 (chain) and HM-03 (hinged) handcuffs. Standard shape fitting many other manufacturers' cuffs. Stainless finish for high mechanical strength and corrosion resistance. Tip for double-locking. Lock-blocking function to prevent further tightening.
Looking for maximum security handcuffs made of durable stainless steel? Need cuffs that restrict the movement of a restrained person and reduce the risk of accidental unlocking or manipulation? The ESP HM-03 jointed handcuffs are designed precisely for this purpose. Crafted entirely from high-grade stainless steel, the cuffs feature a jointed hinge construction that limits opening to 180°, significantly reducing wrist movement. The keyholes are oriented toward the detainee’s body, making tampering or unlocking from the outside much harder. The double-lock mechanism allows you to securely block the cuffs after locking — pressing the side pin with the key tip locks the mechanism and prevents further tightening. With a weight of approximately 450 g, the HM-03 comes with two ESP standard keys and is built for professional police, security, or civilian use.
