LCN 4040XP CUSH, Door Closer - CUSH-N-STOP Arm

The LCN 4040XP Cush door closer is the heavy-duty, Grade 1 surface closer built for high-traffic and high-abuse commercial openings, fitted here with the Cush-N-Stop parallel arm. The Cush-N-Stop arm is what sets this configuration apart: it has a built-in cushioned stop in the soffit shoe that absorbs the door at the end of its swing and acts as a positive stop. On many openings that means you do not need a separate overhead stop or floor stop, because the arm does both jobs.

What the Cush-N-Stop Arm Does

A standard closer arm controls closing only. The Cush-N-Stop arm adds a stop function, cushioning the door near full open and stopping it before it can swing into a wall or adjacent hardware. That protects the door, the frame, and whatever sits behind it. It is the right call for exterior doors in windy conditions, doors with no wall to mount a separate stop, and high-traffic entries where users push hard.

Worth knowing before you order: the 4040XP Cush family has several arm versions. The base CUSH (this product) is a rigid cushioned stop. The SCUSH adds a spring in the arm for extra resistance on wind-load doors. The HCUSH adds hold-open, and the SHCUSH combines spring and hold-open. If your opening needs the door to stay open or fights heavy wind, confirm which arm you want, because they are not interchangeable after install.

Why Buyers Choose the LCN 4040 Closer

The LCN 4040XP is widely regarded as the benchmark heavy-duty closer, and the reason is durability that runs past the spec sheet. The XP build adds increased bearing load capacity, a stronger pinion, and a longer-life seal over the older 4040 closer it replaced (formerly the 4041). For schools, hospitals, retail entries, and any door that cycles thousands of times a week, the lcn 4040xp door closer is the closer specifiers reach for when callbacks are not an option.

The Cush-N-Stop configuration narrows that down further. If your opening needs both reliable closing and a built-in stop, this is the single piece of hardware that handles both, which simplifies the door schedule and the install.
