LCN 4412HSA-REG 24V LH 689 Sentronic Holder/Closer AL combines advanced technology with robust construction, making it an ideal choice for high-traffic environments. This regular arm door closer is engineered with a built-in scanner that activates the hold-open feature, allowing pedestrians to pass through effortlessly.

It utilizes LCN’s heavy-duty 4000 Series cast iron closer, providing durability and reliability. In the event of a power interruption, the closer functions as a full rack and pinion unit, ensuring seamless operation. This model supports concealed or surface wiring and comes standard with a 24V cylinder, with a 120V option available via a compatible transformer. The full metal cover in a matte silver finish not only adds to the aesthetic but also enhances longevity.
