Project Description

17 Hartwell Avenue is a 312-unit multifamily residential development located in Lexington, MA, including a 2,100 SF retail building. Recently, this large-scale project required soft closing hinges for its ongoing construction.

Waterson’s K51M-450 self closing door hinge was selected to replace the need for a separate door closer and hinge. The 3-hinge configuration per door delivers consistent, adjustable self-closing performance while the included WP01 door stop (2 per door) protects walls and frames, keeping the installation neat and code-compliant without additional hardware.
