This regular arm door closer features an 18-inch mounting plate and is designed for right-handed installations.

Ideal for commercial settings, the LCN Sentronic HSA series allows for selectable hold-open periods of either 15 or 30 seconds, making it versatile for varying traffic patterns. The heavy-duty cast iron construction of the 4000 Series ensures durability, while its dual-functionality as a full rack and pinion closer when power is interrupted adds reliability. The closer comes with both concealed and surface wiring options and is shipped with a standard 24V cylinder; a 120V option is available with an additional transformer. With a 150-degree swing and hold-open capability, it is engineered for efficiency and ease of use. Finished in matte silver (689/US28), this surface-mounted closer is built for commercial installations and is backed by a two-year limited warranty, making it a dependable choice for any building professional.

Sentronic Holder/Closer AL

Regular Arm Door Closer with 18 Mounting Plate, 24V, Right Hand, Aluminum

The 4410HSA Sentronic is an electrically controlled closer/holder designed to provide easy passage for groups of pedestrians through high traffic doors. Pedestrians moving through the doorway trigger the built in scanner. When the door is opened to 80 Deg. or more, the door is electrically held open to minimize wear on the door hardware. After the last pedestrian in a group passes through the doorway, the system timer releases the hold open, closing the door. The double lever trach arm closer is designed for push side mounting.

The LCN Sentronic HSA (Holder Scanner Activated) is a door closer with a scanner activated hold open feature.

The 4410HSA Series is designed to hold the door open as there is traffic passing through the opening. Pedestrians, moving through the doorway, trigger the built-in scanner. When the door is opened to 80° or more, the door is electrically held open to minimize wear and tear on applied door hardware.
