Window Security Chain Lock – Steel Cable Restrictor with 18cm Reach for Baby Safety

Keep your home secure and your little ones safe with this practical window security chain lock. Designed to prevent children from accidentally opening windows, cabinets, cupboards, and other hinged or sliding fixtures, this lock gives you peace of mind without complicated installation. The adhesive base uses double-sided glue for quick mounting on clean surfaces, and the steel cable provides a reliable physical barrier. With a cable distance of up to 18cm and a total locking head length of 23cm, it offers a generous range of movement while still restricting opening to a safe limit. Choose between white or black finishes to blend with your existing hardware.

Features and Construction

Built from steel with a surface electroplated zinc alloy coating, this lock resists paint flaking and everyday wear. The lock body is fully sealed to protect internal components, helping extend its service life.

Material and Build

The core cable and locking mechanism are made from steel, providing dependable strength for securing doors and windows. A layer of electroplated zinc alloy covers the surface, preventing paint from falling off and maintaining a clean appearance over time. The entire lock body is sealed during manufacturing, which reduces the risk of dust or moisture entering the mechanism.

Size and Practical Fit

The cable allows a distance of up to 18cm, while the locking head adds another 5cm for a total length of 23cm. This range suits most standard window frames, cabinet doors, and cupboard fronts. The compact design does not obstruct normal use when unlocked.

Uses and Placement

This restrictor lock is suitable for multiple locations around the home, especially where child safety is a concern. The adhesive mounting means you can fit it without drilling holes.

Event or Professional Use

Perfect for landlords, letting agents, or childcare facilities that need temporary or permanent childproofing. The adhesive base can be removed cleanly when no longer needed, minimising damage to surfaces.

Everyday Home Use

Fit it to a living room window to limit how far it opens, or attach it to a kitchen cupboard door to keep cleaning supplies out of reach. The white or black colour options help the lock blend with common window and cabinet finishes.

Benefits and Buying Value

This lock offers a simple, cost-effective way to improve home safety without complex tools or professional fitting.

Reuse and Low Maintenance

The adhesive base can be repositioned if you move house or change your mind about placement. The sealed lock body requires no ongoing lubrication or adjustment, reducing the maintenance burden.

Why Choose This Product

The unique lock core adds an extra layer of security compared to basic sliding bolts. Combined with the corrosion-resistant zinc alloy finish and generous 18cm cable reach, this lock provides both flexibility and reliability for everyday child safety needs.
