4 Pack Window Restrictor for UPVC, Stainless Steel Child Safety Lock

• 【Complete 4-Piece Set for All Windows】This pack includes 2 left-handed and 2 right-handed window restrictors, covering both sides of your UPVC windows. No need to buy separate sets – simply install on all casement windows in your home for consistent child safety protection.
• 【Heavy-Duty Stainless Steel Construction】Made from thickened 304 stainless steel, these window locks resist rust, corrosion, and daily wear. Unlike cheap plastic or thin metal alternatives, they maintain their strength and appearance even in humid kitchens or coastal environments.
• 【Removable Design for Cleaning & Maintenance】Each restrictor features a detachable hook that can be easily removed without unscrewing the base plate. This allows you to clean windows, replace seals, or fully open the window for ventilation – then reattach the safety lock in seconds.
• 【Smooth Rounded Edges for Safety】Every edge is carefully rounded and polished to prevent scratches, snags, or injuries during installation and daily use. Safe for curious little hands and gentle on window frames, these child safety locks prioritise your family’s wellbeing.
• 【Simple DIY Installation with Included Screws】Pre-drilled mounting plates and 16 stainless steel screws are included. Align the restrictor with your window track, tighten with a screwdriver, and enjoy instant peace of mind. Works with standard UPVC casement windows – no professional help needed.

Imagine a sunny afternoon in your living room. You open the window to let in fresh air, knowing your toddler is playing nearby. With these stainless steel window restrictors installed, the window opens only to a safe gap – wide enough for a breeze, narrow enough to prevent any fall. You relax, sip your tea, and watch your child explore safely. That’s the reassurance our window safety locks provide. Crafted from thickened 304 stainless steel, each restrictor is built to withstand years of use without rusting or bending. The removable hook design means you can detach the safety catch when you need full window access for cleaning or emergency exit, then reattach it effortlessly. Smooth, rounded edges protect both your window frames and your family’s hands. The set includes 2 left-handed and 2 right-handed units, perfectly matched for pairs of casement windows. Installation is straightforward: mark the position, drill pilot holes if needed (screws included), and secure the base plate. The restrictor snaps into place and locks automatically when the window is closed. Ideal for homes with children, pets, or elderly residents, these window restrictors for UPVC offer reliable security without compromising ventilation.
