LCN 4111-3071 RH 689 – Frequently Asked Questions

1) Do I need to know the handing before ordering an LCN 4111-3071 cylinder assembly?
Yes, handing is a required choice. The 4111-3071 cylinder assembly is handed and ships as either LH (left hand) or RH (right hand), so match it to the closer already on the door rather than to a generic part number. Get it backwards and the assembly will not drop into the existing closer body. Determine handing from the door as it is installed, then order that hand in the finish you need.
2) Will the 4111-3071 fit my existing LCN 4110 closer without modifying the door?
It is the OEM cast iron cylinder assembly built for LCN 4110 Series closers, so it goes back into an existing 4110 installation with no work to the door or frame. Nothing about the mounting prep changes; you are replacing the cylinder body inside the closer you already have. Confirm the closer on the door is a 4110 Series unit and match the handing.
3) My LCN closer is leaking oil and won't control the door anymore. Can I replace just the cylinder instead of the whole closer?
On a 4110 Series closer, yes. The 4111-3071 is sold as a replacement cylinder assembly on its own, so a failed closer body can be swapped without pulling the arm, the shoe, or the mounting plate and without re-drilling the door. That is the point of the part: restore closer function on an opening whose prep and trim are already set. Order it in the handing that matches the existing closer.
4) What finish options does the LCN 4111-3071 come in, and how do I match the closers already in my building?
Six architectural finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Those are the standard BHMA finish numbers your hardware schedule already uses, so pull the number off the existing closer cover or the door schedule and order the same one. Every finish is available in both left hand and right hand, so finish and handing are independent choices.
5) Is a cast iron closer cylinder worth it for a high-traffic commercial entrance?
Cast iron is what LCN uses on the 4110 body for exactly that duty. The 4111-3071 assembly is cast iron and rated for commercial and institutional applications, which is the traffic level in office buildings, schools, healthcare corridors, and multi-family common doors. For an opening cycling all day, an aluminum-bodied residential closer is the wrong tool; this is the heavy-duty replacement.
6) Is the LCN 4111-3071 ADA compliant for a public facility?
Yes. The 4111-3071 cylinder assembly is ADA compliant for commercial door control installations, which matters on any opening in a government, healthcare, education, or multi-family building where the closer has to meet federal accessibility requirements. Compliance in practice still depends on how the closer is adjusted on the door, but the part itself is rated for ADA applications.
7) What exactly am I getting with a 4111-3071, the whole closer or just a part of it?
It is the cylinder assembly, the cast iron body of the closer, not a complete closer package. Arms, shoes, brackets, and covers are separate. Order this when the closer body itself has failed and the rest of the installation is sound. If you are hanging a new door with no closer on it at all, you want a complete 4110 Series closer instead.
8) How do I spec the LCN 4111-3071 on a purchase order?
Three things: model 4111-3071, the handing (LH or RH), and the finish number. That is the full ordering string, and all twelve combinations of the two hands and the six finishes are stocked. For closer body compatibility and installation detail, the LCN Full Line Catalog is the reference document.
