Master Series 4 Pack Bondage Lock Set

Master Series 4 Pack Bondage Lock Set with Keyed-Alike Keys in Canada

The Master Series 4 Pack Lock Set provides four compact bondage restraint padlocks that all operate with the same key cut, simplifying multi-point locking scenes. Four matching padlocks and four identical keys are included, so any supplied key can unlock any of the four locks. Each low-profile lock measures approximately 1.4 × 0.8 × 0.4 inches and is designed to fit many compatible locking cuffs, collars and restraint hardware without adding unnecessary bulk. Made from nickel-free zinc alloy and iron, the set is available in Canada from Discreet Life for shoppers who want a coordinated locking system with multiple backup keys rather than managing a different key for every restraint point.

Four Locks with Four Identical Keys

All four padlocks are keyed alike. Instead of matching a particular key to a particular lock, any of the four supplied keys operates every lock in the set.

Simplified Multi-Point Restraint

A keyed-alike system is particularly useful when several compatible locking restraints are being used at once. One active key can control all four locks while the remaining keys are kept as backups.

Compact 1.4-Inch Lock Bodies

Each lock measures approximately 1.4 inches long × 0.8 inches wide × 0.4 inches deep. The compact profile helps reduce unnecessary bulk when attached to compatible collars, cuffs and small locking tabs.

Nickel-Free Zinc Alloy & Iron

The locks are constructed from zinc alloy and iron and are identified as nickel-free.

Designed for Compatible Locking Restraints

The supplier describes the locks as fitting most locking restraints, including cuffs, collars and common locking hardware. Because shackle openings and restraint tabs vary, check the dimensions and fit before beginning a scene.

Compare Lockable Master Series Restraints

This lock set is accessory hardware rather than a restraint by itself. Among the related Master Series products below, Femme Fatale and Trapped have hardware designed to accept a compatible padlock, while Cuffed already has its own built-in lock and Misbehaved uses a cut-off release instead.
