LCN 4050A-3071 689 – Frequently Asked Questions

1) What is the LCN 4050A-3071 and what is it used for?
It is a replacement cylinder assembly for LCN 4050A Series door closers, made of cast aluminum. It is a service part, not a complete closer, so you order it when the closer body's cylinder assembly needs replacing rather than when you need a new door control.
2) Do I need to specify left hand or right hand for the LCN 4050A-3071 cylinder assembly?
No handing to specify. The 4050A-3071 is non-handed, so the same part works on left hand and right hand openings. That is useful if you stock spares for a building with closers swinging both ways.
3) Will the 4050A-3071 cylinder assembly fit a closer from another LCN series, like a 4040XP or 1460?
No. This cylinder assembly is built for the LCN 4050A Series and should be matched to a 4050A closer. Cylinder bodies differ between LCN closer families, so pull the series number off the closer cover before ordering.
4) What finishes can I get the LCN 4050A cylinder assembly in?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Match the code stamped on the existing closer so the replacement blends with the rest of the openings in the building.
5) Is this LCN cylinder assembly rated for a high traffic commercial entrance?
Yes. The 4050A-3071 meets BHMA Grade 1, the heavy duty tier, and is a commercial-rated part. It suits office buildings, schools, hospitals, retail, and government facilities where the closer cycles constantly.
6) Does replacing the cylinder assembly keep my door ADA compliant?
The 4050A-3071 is listed as ADA compliant, so a properly adjusted 4050A closer using this cylinder can still be set to meet accessibility opening force requirements. Compliance on the finished opening still depends on how the closer is adjusted after the swap.
7) Why cast aluminum for a door closer cylinder?
Cast aluminum gives corrosion resistance and holds up in demanding environments, which matters on exterior and high-humidity openings where a closer body sees weather. It is the same material approach LCN uses across its heavy duty commercial closers.
8) Is the 4050A-3071 something a maintenance tech can install, or does it need a hardware specialist?
It is sold as a professional service part, intended for installation by someone who works on door controls. Swapping a cylinder assembly means pulling the closer, transferring the arm and adjusting closing and latching speed afterward, so a maintenance tech comfortable with closers can do it; a first-timer should not learn on a fire-rated opening.
