LCN 1450-3077EDA 689 – Frequently Asked Questions

1) What is the LCN 1450-3077EDA and what does it replace on a door closer?
It's the extra duty arm assembly for LCN 1450 Series door closers. It's the arm linkage between the closer body and the door or frame, sold on its own so you can swap out a bent or worn arm instead of pulling and replacing the whole closer. The closer body, valves and spring stay in place.
2) Will the 1450-3077EDA arm fit my LCN 4040 or 1250 closer?
No. The 3077EDA extra duty arm is built for LCN 1450 Series closers. Arm assemblies are matched to the closer body's pinion spline and shoe geometry, so ordering it for another LCN series will leave you with a part that won't mount. Confirm the series stamped on your closer body before you order.
3) Why would I use an extra duty arm instead of the standard closer arm?
Extra duty arms are the answer to abuse openings: high traffic doors, doors that get pushed past their stop, wind-loaded exterior entrances. The heavier arm construction takes the impact that bends a standard arm. If you're replacing the same arm on the same door for a second time, the extra duty version is the part to move to.
4) What finishes does the LCN 1450 extra duty arm come in?
Six painted and plated finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. For a repair, match the number on the existing closer cover so the arm doesn't read as a mismatched part on the opening. 689 aluminum and 695 dark bronze are the two you'll see most often on commercial entrances.
5) I manage a building with a dozen LCN 1450 closers. Can I stock one arm to cover all of them?
Yes, provided they're all 1450 Series. The 3077EDA is the same arm assembly regardless of which door it goes on, so one spare covers the fleet. The only thing that varies across your openings is finish, so stock the spare in whatever finish dominates your entrances (689 aluminum or 695 dark bronze on most commercial buildings).
6) Does the LCN 1450 arm assembly come with the mounting screws and shoe?
The 3077EDA is supplied as an arm assembly, which is the arm and its shoe linkage as a unit. Reuse the existing fasteners and soffit or frame bracket that are already on the door if they're sound. If the frame bracket itself is damaged along with the arm, that's a separate part and needs ordering alongside.
7) Do I need a locksmith to install this, or can maintenance staff do it?
An arm swap is within reach of maintenance staff who have done closer work before, but the closer has to be de-tensioned and the arm re-preloaded to restore the original closing and latching speed. LCN calls for installation by technicians familiar with LCN closer adjustment procedures. If nobody on site has set closer preload before, put it with your door hardware contractor.
