LCN 4011-REG Door Closer - Mounting Hinge Side (Pull Side) - Regular Arm

The LCN 4011-REG is the pull side regular arm configuration of the LCN 4010 Smoothee, one of LCN's flagship heavy duty commercial door closers. The 4010 Smoothee is the LCN series built specifically for institutional and high-traffic applications: cast iron body, forged steel arm, double heat-treated steel pinion, all-weather fluid, and LCNFastPower Adjust for fast and accurate closing speed calibration in the field.

Pull side means the closer mounts on the hinge side of the door. When you stand on the pull side of a door (the side you pull toward you to open), the hinges are visible on the same side. The 4011 mounts in that configuration with the regular arm. For push side mounting, the 4021 (parallel arm version) is the correct model. Confirm your door swing before ordering between the 4011 and 4021. For all LCN and commercial door closers, browse our door closers catalog.

Non-Sized: One Closer for All Widths

Most commercial door closers require you to specify a size (1 through 6) based on the door width and weight. The LCN 4011 uses a non-sized adjustable cylinder that covers interior doors from 24 to 54 inches wide and exterior doors from 24 to 42 inches wide in a single unit. You set the closing power after installation using the LCNFastPower Adjust feature, which allows accurate adjustment through the cover without removing it. This eliminates the size-selection guesswork during specification and reduces the number of SKUs a facility needs to stock for door closer replacements.

LCNFastPower Adjust

LCNFastPower Adjust is LCN's field adjustment system built into the 4010 Smoothee. After installation, the closer's power is set at the keyhole-accessible adjustment point on the cover without removing either the cover or the closer from the door. The adjustment is fast enough that an installer can set the power, test the closing action, and fine-tune in a single visit. For ADA compliance on interior accessible doors requiring 5-pound maximum opening force, the LCNFastPower Adjust allows precise field calibration after the door is hung and under real load conditions.

Delayed Action (DEL) Option

The 4011 is available in two configurations: Standard Model and DEL (Delayed Action). The Standard Model closes the door at normal closer speed from fully open to latched. The DEL option adds a delay phase: when the door is opened fully, it holds briefly at the maximum opening before beginning the closing sweep. Delayed action is specified on healthcare doors, ADA accessible doorways, and any opening where occupants need extra time to pass through before the door begins closing. Confirm whether the application requires the DEL option at time of order - it cannot be added to a standard model in the field.
