Lcn 3133STDALRH Concealed Door Track Closer Size 3 Rh

Product Description

The LCN 3133STDALRH is a size 3 concealed in-door track closer designed for right-hand door applications. The closer mechanism installs inside the door and operates through a concealed track system, keeping hardware out of sight while delivering consistent controlled latching and closing action. At 6.75 pounds and finished in 689 aluminum, it is built for high-traffic commercial and institutional environments where appearance and durability are both priorities. Licensed door hardware technicians and commercial contractors are the primary installers. The 689 aluminum finish provides a clean, low-profile look suited to facilities where exposed hardware is undesirable.

The 3133STDALRH is designed for interior and exterior doors in commercial and institutional settings, including schools, hospitals, government buildings, and correctional facilities. Its concealed track configuration makes it appropriate for high-visibility openings such as corridor doors, office entries, and public-facing door assemblies where a clean aesthetic is required alongside reliable door control. The right-hand designation must be confirmed against the door handing before ordering.

Installation Notes

Installation should be performed by a licensed door hardware technician or qualified commercial contractor familiar with concealed closer systems. Confirm door handing and door preparation dimensions before beginning installation, as concealed closers require precise mortising into the door body. Verify that the door and frame construction are compatible with the concealed track mounting system prior to cutout. Follow all applicable local building codes and ADA requirements for door closing force and speed.
