Windy or not, We get it covered!

The invisible air molecules are always rushing rapidly in both open and confined spaces. The overall dynamics of these molecules determine the air pressure that we can perceive.

When you open or close windows, these molecules are either pulled in or pushed out of the room, and consequently the air pressure will be changed. This is when the self-closing of door will be influenced and even inconsistent.

Do you have difficulty finding a door closer that can overcome this dilemma? Waterson hinges cover it all!

Windows opened–problems of wind and drafts

Door closing is accelerated by wind

Windows closed–problems with positive air pressure

Door won’t latch properly because of the differences of air pressures inside and outside of the room

W41K- Compatible with your current doors; seamless replacement to your hinge!

No need to consider the thickness of hinge leaves or gap sizes of door and frames.
Simply install and enjoy the self-closing convenience right away.
