Swing Clear Self-closing Hinges

Also known as “offset door hinges” or “expandable door hinges,” the swing clear hinge’s unique leaf design can maximize door openings by allowing doors to “swing away,” creating more space. When space constraints or clearance issues exist, this added space can be beneficial for meeting accessibility needs, as well as ADA and FHA codes.

The Waterson K51L-SW hinge uniquely combines swing clear design with our patented self-closing function in an innovative and attractive stainless steel component. Easy to install and heavy-duty, the K51L-SW meets Fair Housing Act (FHA) code, and thus provides a minimum 32” clearance when using a 34” door slab. This attractive hinge is also fire-rated hardware that meets ADA requirements as well. Combined, the Waterson swing clear self-closing hinge provides optimal user experience in wheelchair-accessible doorways like hospitals, hotels, multi-family housing, and nursing homes, to name a few.
