LCN Door Closers

Shop LCN door closers and door-control parts for commercial, institutional, office, school, storefront, and other high-use openings. This collection includes surface-mounted closers, closer arms, hold-open arms, covers, drop plates, mounting brackets, rod-and-shoe assemblies, and other replacement components for LCN closer systems. When selecting a closer or service part, confirm the LCN series, mounting style, arm configuration, door size, finish, and any accessibility or fire-rating requirements that apply to the opening. Replacement parts are often series-specific, so matching the existing closer model and manufacturer reference is especially important.

Choosing LCN Door Closers and Replacement Parts

LCN door closers are used on commercial and institutional openings where controlled closing is important for security, accessibility, comfort, and door performance. Start with the closer series and the mounting condition. Surface-mounted closers may be installed in regular-arm, top-jamb, or parallel-arm configurations, and each arrangement can require a different arm, bracket, plate, or fastener package.

Closer size or adjustment range, door width and weight, frame conditions, traffic level, and environmental conditions can affect the correct closer selection. Hold-open arms should only be used where hold-open operation is appropriate for the opening. For rated openings or projects with accessibility requirements, review the exact closer documentation and project requirements rather than assuming that every closer configuration is suitable.

LCN replacement parts such as covers, arms, rod-and-shoe assemblies, drop plates, brackets, and mounting components are commonly tied to a specific closer family. A part that looks similar may have different mounting holes, geometry, or operating characteristics. Identify the existing closer series and compare the manufacturer reference on the product page before ordering a repair component.

Mounting plates and brackets can help accommodate narrow rails, unusual frame geometry, deep reveals, or other conditions that prevent a standard installation. Arm selection also changes how the closer transfers force to the door and frame. Review the mounting instructions for the exact model so the closer body, arm, plate, and fasteners work together as intended.

For replacement or renovation work, begin with the model information on the existing LCN closer whenever possible. Then confirm the mounting style, arm type, door dimensions, finish, and any required features before selecting parts. This approach is more reliable than matching by appearance and helps avoid changing an opening unnecessarily when a compatible service component is available.
