The ERA 812 uPVC Ventilation Lock has been designed especially for PVCU windows and doors. With its shaped and robust styling the ventilation lock is an excellent home safety device allowing the window to be opened for air flow but remain locked preventing entry through the window. It is simple and easy to use with no key required. It can be used on PVCU doors in the same way that a door chain is used, but as there is no chain, the door will not be scratched. As the product is non-handed it can be used for inward and outward opening doors. The ERA 812 lock is available in white and two different packing pieces are provided to cater for the differing heights between the leaf and frame. easylocks are the UKs main suppliers for ERA 812 uPVC Ventilation Locks.
