Lcn 2011STDALLH Concealed Door Closer Size 1 689 Aluminum

Product Description

The LCN 2011STDALLH is a concealed in-frame door closer designed for left-hand regular applications. Installed entirely within the door frame, this size 1 closer keeps the hardware out of sight while delivering controlled, consistent door closure. It ships as a single unit and measures 23.2 inches in length, 5 inches in width, and 4.7 inches in height, with a finished weight of 11.65 pounds. The 689 aluminum finish provides a clean, neutral appearance suited to commercial and institutional interiors. Installation is handled by commercial door hardware technicians and finish carpenters working on new construction or retrofit projects.

Concealed in-frame closers are widely specified for high-traffic facilities including schools, hospitals, government buildings, and correctional facilities where exposed overhead closers are either undesirable or prohibited by design standards. The 2011STDALLH suits interior and select exterior doors where a clean frame profile is required and where the left-hand regular door swing configuration matches the opening geometry. This is a size 1 unit, appropriate for lighter-duty door applications within that closer-size range.

Installation Notes

Concealed in-frame closers require precise mortising of the door frame and are typically installed by commercial door hardware specialists or qualified finish carpenters. Power down any access control or electric hardware integrated into the frame before beginning work. Follow the door and frame manufacturer's template instructions exactly, as misaligned pockets will affect closer function. Verify that the door hand and swing direction match the 2011STDALLH left-hand regular specification before installation.
