6PCS Window Restrictors, Locks, UPVC Safety Catches

Added Window Opening Protection: These window restrictors hold compatible windows in a limited open position, helping prevent cats or children from pushing them open too widely and reducing the risk of accidental falls. The stainless steel hook mechanism also adds resistance against casual forced opening, providing an additional layer of household protection. Simple to Install and Operate: Each UPVC window lock has pre-drilled mounting holes and comes with matching fixing screws. Select the appropriate left- or right-hand catch, mark the mounting position and secure it to a suitable window frame. Lift the hook when wider access is needed and reconnect it afterwards to restore restricted opening. 304 Stainless Steel Construction: These stainless steel catches are made from durable 304 stainless steel with a smooth silver finish. The sturdy metal structure provides reliable strength and offers good resistance to daily wear, moisture and corrosion, making them suitable for repeated indoor use. Controlled Ventilation Design: These window restrictors are designed to limit the opening angle of compatible windows while allowing fresh air circulation. The installation position determines the opening distance, helping maintain ventilation while reducing excessive window movement. Please confirm the required position before drilling. Wide Indoor Applications: These UPVC window locks are suitable for compatible casement windows in homes, apartments, offices, schools, nurseries and rental properties. The set includes 3 left-hand and 3 right-hand fittings to suit different opening directions.
