Pet & Child Lever Handle Door lock

My cats kept opening doors and getting into rooms they were not allowed into… No longer! 

This device disables the downward travel of lever handled doors by blocking them, the door can still be opened by lifting the door handle upwards. 

To use, slightly unscrew the plate from your door handle and fit the 3D-printed piece behind it. The included file accommodates a plate roughly 66mm in diameter, you may have to flex the part slightly to get into place. Once in place screw the plate down tight clamping the printed part in place so that it may not rotate.
