LCN 3031-652 – Frequently Asked Questions

1) Will the LCN 3031 concealed closer work in a 1-3/4 inch interior door?
That is exactly what the 3031 is built for. It mounts concealed in the door itself on 1-3/4 inch interior doors up to 4'0" wide. Exterior openings are outside its stated application, so for a door to the outside you want a different closer.
2) Do I have to specify handing when ordering an LCN 3031?
Yes, handing is a required choice on the 3031. It is ordered either right hand or left hand, and the default is right hand. Because the closer body sits inside the door, a wrong hand cannot be flipped in the field the way a surface closer often can, so confirm the swing before you order.
3) Is the LCN 3031 ADA compliant for reduced opening force?
It meets the ADA reduced opening force requirement, and it is ANSI/BHMA A156.4 Grade 1 certified plus UL and cUL listed. For a school or healthcare corridor where accessibility and Grade 1 both get specified, the 3031 answers both lines on the schedule.
4) What arm options come with the LCN 3031 concealed closer?
Two arm choices, and one has to be picked with the order: the standard regular arm (REGARM), which is the default, or a hold open arm (H) if the opening needs to stand open at a set point. Both use the double lever arm configuration of the 3030 Series.
5) What finishes does the LCN 3031 come in?
Six plated finishes: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome. The plating is on the arm and fasteners, which is the only part visible once the cylinder is buried in the door, so matching the lever trim on the rest of your openings is straightforward.
6) Does the LCN 3031 have a delayed action function?
No delay function on the 3031. You get separate adjustment of general closing speed and latching speed through tamper-resistant regulating screws, but no delayed close. If an opening needs extra time for carts or slower traffic, specify a closer with delayed action instead.
7) Can the LCN 3031 handle a busy corridor, or is it too light duty?
It is rated medium duty and built for medium- to high-traffic commercial openings: cast iron cylinder, 1-1/8 inch diameter forged steel piston, and a full-complement bearing. For an office, school, or retail interior door it is the right class of product. For an abused exterior entrance, look at a heavier exterior-rated closer.
8) Is the LCN 3031 Buy American Act qualified for a government job?
Yes, the 3031 is BAA qualified, which is what a federal, municipal, or public-agency spec usually asks for. Pair that with the Grade 1 certification and UL/cUL listing and it clears the usual government hardware schedule requirements.
9) What size is the LCN 3031 closer, and does that cover a 3'0" door?
The 3031 is a size 1 closer, sized for interior doors up to 4'0" wide, so a standard 3'0" interior opening is well within range. Anything wider than 4 feet is outside what this closer is specified to control.
10) What fasteners come with the LCN 3031, and do I need anything else to mount it?
It ships with both wood and machine screws, so it covers hollow metal and wood door mounting without a separate fastener pack. What it does require is that the door be prepped for a concealed closer, since the cylinder mounts inside the door, not on the face. Confirm the door is ordered or morticed to the LCN template before install.
11) Why choose a concealed-in-door closer like the 3031 over a surface mounted closer?
The tradeoff is looks and tamper resistance versus install effort. The 3031 buries the cast iron cylinder inside the door leaf so only the arm shows, which is what architects want on finished lobbies and what facilities want where closers get vandalized. The cost is door prep: the leaf has to be machined for it, so retrofitting an existing undrilled door is a bigger job than screwing a surface closer to the face. If the door is already hung and unprepped, a surface closer is the practical call.
12) Will the LCN 3031 keep working in an unheated building or a garage corridor?
It uses all-weather fluid, so closing speed stays consistent across temperature swings, which matters in warehouses, parking structures, and unconditioned back-of-house corridors. The door itself still needs to be an interior 1-3/4 inch door, since that is the application the 3031 is built around.
