eSynic 10 Pack Window Locks 185mm wire safety for UPVC 🏠

This window safety restrictor provides controlled ventilation while limiting how far a window can open, helping to reduce the risk of accidental falls in homes, nurseries and other settings. It combines robust materials and a key-operated locking system to let you choose between restricted opening and full access when needed, making it practical for everyday use.

Key Points

The unit reduces the opening distance of UPVC and wooden windows to enhance child safety and deter opportunistic theft. Installation uses self-drill screws rather than adhesives, so the fixings are more durable and suited to frame materials such as PVC and UPVC. The mechanism locks with a supplied key, which allows straightforward locking and unlocking when you want full window movement. Consider that, according to the manufacturer, this is a mechanical restrictor and it may not prevent forced entry in all circumstances.

🔒 The pack contains multiple restrictors intended to cover several windows in a property. The finish and materials aim to resist wear and environmental exposure, which is useful for rooms that see frequent use.

Technical Specifications

• Name: eSynic 10 Pack Window Locks Child Safety Durable & Strong
• Material: Zinc alloy and UPVC components
• Wire length: 185mm steel cable
• Pack quantity: 10 pieces
• Fixings: Self-drilling screws included

Usage Recommendations

Fit the restrictor aligned with the window frame so that the cable limits the sash travel to the desired distance. For best results, test the position before final tightening and keep the supplied key in a secure but accessible place. These restrictors work well in bedrooms, playrooms and ground-floor windows where ventilation is needed while limiting opening width 🏠. When opening the window fully, unlock with the key and remove the cable from the catch, then reintroduce and lock it when you want the restricted position again.

Advantages

This solution offers a straightforward mechanical approach to reduce fall risk while allowing controlled ventilation. It is relatively unobtrusive on the frame and does not rely on adhesive methods that can degrade over time. The 185mm steel cable provides a clear limit to sash movement and the zinc alloy components add weight-bearing capacity compared with some lighter plastic fittings. A possible limitation is that for very heavy or unusually sized windows additional reinforcement or alternative fittings may be preferable according to the specific installation conditions.
