Lcn 2013STDALLH Concealed In-frame Door Closer Size 3

Product Description

The LCN 2013STDALLH is a concealed in-frame door closer designed for left-hand regular applications. It installs fully within the door frame, keeping the closing mechanism out of sight while delivering consistent, controlled door movement. This is a Size 3 closer, meaning it provides a closing force appropriate for standard interior and light commercial doors. At 11.7 pounds and measuring 23.1 inches in length, 4.7 inches in width, and 4.1 inches in height, the unit is built for durability in demanding environments. The 689 aluminum finish gives it a clean, low-profile appearance suited to commercial interiors. Licensed door hardware technicians and commercial contractors are the typical installers.

This closer is intended for high-traffic commercial installations where a visible surface-mounted closer is not acceptable. Concealed in-frame closers are commonly specified in schools, hospitals, government buildings, correctional facilities, and other institutional settings where door hardware must perform reliably under heavy daily use. The left-hand regular configuration determines hinge-side and swing orientation and must match the door hand before ordering. This unit ships as a single assembly (sold per each) and is available in case quantities of four.

Installation Notes

Installation of concealed in-frame closers requires precise routing or mortising into the door frame and is typically performed by a licensed door hardware technician or commercial contractor. Verify door hand and swing direction before installation, as an incorrect hand selection will prevent proper function. Consult the applicable building code and door manufacturer specifications for frame preparation dimensions and fastener requirements. Ensure all work complies with ADA and local accessibility codes where applicable.
