The Inventco sliding door closer from Locks Galore is commonly known as the water door closer due to the fact that it uses a patented speed limiting valve that operates within the door mounted closer tube, which is water filled.

The closing speed of the door is suppressed, resulting in a gently latching action.

The Inventco water door closer is easily fitted to sliding security screen doors which conform to Australian Standards. It quietly and consistently closes the sliding doors.

In addition to its use as an automatic screen door closer, it has been extensively used to satisfy swimming pool safety laws, which exist in all Australian states and are being adopted throughout the world.
