Couldn't load pickup availability
The LCN 4021 regular arm door closer is a heavy-duty surface-mounted closer in the 4020 Series for top-jamb mounting on the push side of the door. Choose left-hand or right-hand configurations in aluminum, black or dark bronze. The REG models on this page use a regular arm; match the complete SKU, handing and finish before ordering.
LCN 4021 Configuration and Mounting
The closer has a cast-iron cylinder and is designed for commercial openings. Confirm the frame reveal, available mounting space and desired opening angle against the manufacturer’s template. For replacement work, check the existing mounting preparation rather than assuming another LCN model uses the same holes.
Available configurations pair each finish with left-hand or right-hand operation: aluminum 4021REGALLH / 4021REGALRH, black 4021REGGLBLKLH / 4021REGGLBLKRH, and dark bronze 4021REGDKBRZLH / 4021REGDKBRZRH.
Installation Instructions and Related Closers
Download the official LCN 4020 Series installation instructions for the 4021 for mounting templates, handing and adjustment guidance. Follow the document for the selected configuration and opening. See the LCN series resources for additional catalog information.
Compare LCN 4011 pull-side closers or LCN 4111 parallel-arm closers when your application requires a different mounting arrangement. Browse all LCN surface mounted door closers, or visit LCN door closer parts for replacement components.
