LCN 4040SE Standard Track Non-Stranded for SE Closers, 24V, Brass

Dependable door control for commercial interior applications— the LCN 4040SE door closer delivers reliable performance and simplified integration with security and access control systems. Built by LCN to ANSI A156.15 standards, this SE closer provides proven durability and consistent closing force for interior doors up to 4'0". The 24V SE track and momentary on/off switch support hold-open release and can be tied into monitoring, surveillance, or alarm systems for centralized control and automated operation. Non-sized cylinders and a non-handed design allow quick installation on left or right hand doors, while concealed or surface wiring and a brass finish make it ideal for aesthetic-sensitive retrofit projects. When hold-open is not engaged the closer functions as a full rack-and-pinion unit, ensuring smooth, controlled closings that protect hardware and enhance building security. Choose the LCN 4040SE for dependable door control that integrates with your access control and monitoring strategy.
