Waterson hinges are ideal for a variety of commercial applications, environments and conditions. Choose either Mechanical self-closing or Hydraulic Hybrid soft-close depending upon your particular needs.

PURELY MECHANICAL

Waterson mechanical hinges are ideal for high frequency use heavy doors. State-of-the-art heat-treated carbide components and EN-certified springs ensure durability, effectiveness, and longevity.  Your heavy-duty commercial doors will close effectively at a controlled speed every time. Ideal for hotel rooms, fire-rated doors, and archtop openings, to name a few.

HYDRAULIC HYBRID

On the other hand, if quiet is a chief concern then you may want to consider choosing the Waterson hydraulic hybrid self-closing hinge due to oil-controlled dynamic braking.  Also an effective closing component, particularly in breezy environments, Waterson hydraulic hinges respond well sans leakage to sudden wind changes with exceptional quietness.  Great for office environments, glass doors and more.
