Manual magnetic lockable Staywell cat flap (Hereford HR1)

Used but fully working Staywell cat flap. Have fully cleaned. Magnet keeps closed unless very windy out and also has manual locking settings, fully locked, open in and out, can go out but not back in or can come in but not back out. Collect 12 Fawley Close, HR1 1AL. Too good to dump. Best wishes, Jonathan
