Police Restraints Guide: Handcuffs, Legcuffs

What Police Restraints Cover

Restraints are the equipment officers use to secure a subject once physical control is gained: wrist restraints in the form of handcuffs, ankle restraints in the form of legcuffs, and combination restraint sets used for high-risk transport. Inside the public order mission, restraints are the closing step — the crowd is dispersed or contained, arrests are made, and every arrested person must be secured safely and humanely for processing.

Restraints belong to the wider riot control equipment package that this guide is part of; the parent guide positions restraints against protective gear, less-lethal tools and barrier accessories so departments can plan one coherent order. Impact tools that precede the arrest are handled by the companion police baton guide, because most arrest teams carry both on the belt. This page covers the handcuff type decision, materials and finishes, the double lock mechanism, legcuffs, and what to specify when sourcing for a department.

Handcuff Types

Three structures dominate police handcuff inventories, and each balances rigidity against control:

The chain style stays the most ordered police handcuff because it balances carry comfort, price and everyday patrol use. Departments that run specialist teams usually keep hinged or rigid models in the armory for those specific assignments.

Materials and Finish

A handcuff is a mechanical tool that must work for decades under sweat, rain and hard use, so material choice decides service life:

The finish matters as much as the steel. Nickel plating is the standard because it resists corrosion and keeps the ratchet action smooth; black oxide finishes suit less visible duty roles. Buyers should look for a finish that survives daily carry and humid storage without flaking into the mechanism, and specify the standard police key pattern so department keys and spares interchange across the whole inventory.

Double Lock and Safety

The double lock is the safety feature that separates a duty handcuff from a display piece. When a single lock cuff is closed on a struggling subject, the ratchet can keep tightening as the person pulls, risking nerve damage in the wrist. Engaging the double lock — a push button or key turn on the bow — stops the ratchet from closing further once the cuff is set at the correct position.

Departments make double lock operation part of arrest training: apply the cuff, check the fit with a finger gap, engage the lock and confirm it before transport. Our high strength police handcuffs with double lock build the mechanism into a heat treated alloy steel body, and the alloy steel police handcuffs carry the same push button lock in a lighter patrol profile. Both release with one standard key turn once the double lock is disengaged.

Legcuffs and Restraint Sets

Legcuffs secure the ankles and are reserved for subjects whose risk profile justifies them: violent arrestees, prisoners in transport and court appearances where escape risk is high. They follow the same engineering rules as handcuffs — hardened steel bows, corrosion resistant plating and a locking mechanism that cannot overtighten.

Agencies that handle high-risk custody sometimes run a two in one approach, pairing ankle restraints with wrist cuffs for rapid application on the most dangerous subjects. The nickel plated police legcuffs cover the ankle restraint role, and the restraints category holds the full range of handcuffs, legcuffs and related restraint hardware for one-stop ordering. Whatever the set, the rule is the same: restraint capacity matches the documented risk, never exceeds it, and always pairs with a clear policy on removal during medical checks.

Sourcing for Departments

1. Write the use case — patrol issue, transport, court or high-risk arrest changes the handcuff type and finish you need

2. Specify steel and finish in the request — heat treated alloy or carbon steel, nickel or oxide finish, double lock mechanism

3. Standardize the key pattern — one key standard across handcuffs, legcuffs and spares simplifies the armory

4. Request samples within 5-7 days — test locking action, double lock engagement and key fit while wearing duty gloves

5. Plan OEM options — agency engraving, serial numbers for evidence tracking and custom packaging

6. Confirm MOQ and lead time — trial orders from 50 pieces per model, MOQ 100 pieces for standard runs, production 20-30 days after sample approval

FAQ

What types of police handcuffs are there?

Chain style, hinged and rigid. Chain style suits general patrol, hinged models tighten control during escort, and rigid cuffs serve high-risk arrest teams.

Why does the double lock matter?

It stops the ratchet from tightening further after the cuff is set, which prevents wrist injury on a struggling subject during transport.

Are legcuffs standard police restraints?

They are standard equipment for transport and high-risk custody, used together with handcuffs when the risk assessment calls for full restraint.

What is the MOQ for department handcuff orders?

Trial orders start from 50 pieces; MOQ 100 pieces applies to standard production runs, with samples shipped within 5-7 days.

Final Word

Restraints are a safety tool for both sides of the arrest: they keep the subject secure and they keep officers out of improvised holds that cause injuries. Choosing tested steel, a reliable double lock and one key standard across the inventory separates gear that works for decades from gear that fails at the worst moment.
