ESP HM-03 Hinged Handcuffs in Stainless Steel — Silver

The ESP HM-03 are double-hinged handcuffs in stainless steel, designed for professional use by law enforcement and security operators. The hinge mechanism allows a maximum opening of 180°, enabling the subject's wrists to be positioned either side by side or separated, with greater postural control than rigid bar handcuffs. Total weight is 450 g.

The polished stainless steel is not chrome-plated: the surface is hypoallergenic and has no galvanic coatings that can flake or oxidise over time. This choice means the mirror finish is more susceptible to surface scratches than a matte coating, but it ensures that the material in contact with the skin contains no deposited nickel. For operators working in humid environments or carrying the handcuffs attached to their kit for extended periods, structural corrosion resistance is the key requirement.

The locking system is a double lock with a side safety pin. The first lock arrests the ratchet at the point of application; the double-lock pin, set with the key, prevents any further accidental or deliberate movement of the bow and reduces the risk of injury from over-tightening. This two-stage mechanism is the operational difference from single-lock handcuffs: it adds a step to the procedure but increases restraint security. The key used is the standard ESP key, two of which are included in the kit.

Key features

• The hinge with an opening of up to 180° provides more wrist-positioning options than a rigid model, adapting to cuffing requirements whether standing, on the ground or secured to a fixed structure.
• The double lock with side pin secures the ratchet in two distinct stages, reducing the risk of unintended bow movement and injury to the detained subject.
• The polished, non-chrome-plated stainless steel is hypoallergenic and has no coatings that deteriorate with continued use or exposure to moisture.
• The weight of 450 g is typical for professional steel handcuffs: heavier than lightweight alloy versions, but with greater structural strength under stress.
• Compatibility with the standard ESP key allows the HM-03 to be integrated into a kit that already uses other products from the same manufacturer, with no need for additional keys in a different format.
