LCN 4050A-3071DEL 689 – Frequently Asked Questions

1) What does the LCN 4050A-3071DEL delayed action cylinder actually do on a door closer?
It is the replacement cylinder that gives an LCN 4050A Series closer its delayed action function, holding the door open longer at the start of the closing cycle before it sweeps shut. That extra dwell is what lets someone using a walker, a wheelchair, or pushing a cart get through the opening. It replaces the standard cylinder in the closer body rather than being an add-on accessory.
2) Will the 3071DEL cylinder fit any LCN closer, or only the 4050A?
Only LCN 4050A Series closers. The 3071DEL is built as a 4050A Series component, so it is not a general-purpose delayed action cylinder for other LCN closer families. Confirm the closer body stamp reads 4050A before you order.
3) Do I have to order the delayed action cylinder handed for a left or right hand door?
No. The 3071DEL is non-handed, so one part covers left hand and right hand openings. For a property manager or facilities crew stocking spares, that means a single cylinder on the shelf works on any 4050A closer in the building regardless of door swing.
4) Is this a door lock cylinder or a key cylinder?
Neither. Despite the word cylinder, the 4050A-3071DEL is a hydraulic door closer component, not a keyed lock cylinder. It takes no key, no keyway, and no cam. If you are after a keyed cylinder for a lock or an exit device, this is the wrong part entirely.
5) Can I add delayed action to an existing 4050A closer that does not have it?
Yes, that is the usual reason to buy the 3071DEL. Swapping in the delayed action cylinder converts a standard 4050A closer to delayed action without replacing the whole closer or re-drilling the door and frame, so the existing mounting and arm stay as they are.
6) Is the LCN 4050A delayed action cylinder ADA compliant?
Yes, the 4050A-3071DEL is ADA compliant. Delayed action is the feature that supports accessible openings by extending the time the door stays open before it begins to close. Note that compliance on the finished opening still depends on the closer being adjusted for the required opening force and closing speed at install.
7) What finishes does the LCN 4050A-3071DEL come in?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Match the finish to the existing closer cover so a repaired opening still looks like the rest of the doors on the floor.
8) Is the 4050A delayed action cylinder suitable for high traffic commercial doors?
Yes. It is a commercial-grade, heavy duty component intended for high traffic openings such as office buildings, schools, hospitals, retail, warehouses, multi-tenant residential, and municipal buildings. It is not a residential-duty part.
