LCN 4040SE-DE 24V LH 689 Sentronic Holder/Closer AL

LCN 4040SE-DE 24V LH 689 Sentronic Holder/Closer AL delivers exceptional performance and reliability for fire and smoke barrier doors. This Grade 1 surface door closer features a slide track arm design that allows for double egress with hold-open functionality at a 95-degree angle. Engineered for heavy-duty use, it offers a single point hold-open mechanism that keeps the door ajar until a current interruption triggers the closure, ensuring safety and compliance. Designed for interior doors up to 4'0", the non-handed closer accommodates left-handed installations and can be mounted on either the push or pull side of the door. The adjustable hold-open force and momentary on/off switch board assembly enhance usability while providing over-voltage protection. Additionally, the LCN 4040SE functions as a full rack and pinion closer when the hold-open feature is not engaged. With its durable plastic cover and aluminum painted finish, this door closer not only meets ANSI A156.15 standards but is also ADA compliant and BAA qualified. Available with standard or custom powder-coated finishes, the LCN 4040SE-DE is a versatile choice for commercial applications, ensuring both functionality and aesthetic appeal.
