Description
The LCN 4040SE Sentronic is a heavy-duty, non-handed door closer and holder designed for fire and smoke barrier doors. It provides single-point hold-open functionality, keeping doors open until power interruption triggers automatic closure. The non-sized cylinder accommodates interior doors up to 4 feet, with adjustable hold-open force and full rack-and-pinion closing when hold-open is not engaged.
This closer mounts on either push or pull side and works on right or left hand doors. Available in 24V or 120V with standard or custom powder-coated finishes; optional plated finishes available. As an authorized LCN dealer, E.D. Locks provides expert guidance on voltage selection, wiring configuration (concealed or surface), and alarm system integration.
