LCN 3034-689 – Frequently Asked Questions

1) Will the LCN 3034 concealed closer fit a 1-3/4 inch interior door?
That is exactly the opening it is built for. The 3034 is concealed in the door itself, and the cylinder is sized for concealment within a 1-3/4 inch interior door on doors up to 4 feet wide. It is an interior-door closer, so it is not the pick for an exterior entrance. If your door leaf is thinner than 1-3/4 inches or wider than 4 feet, this is the wrong closer for that opening.
2) Do I have to specify handing when ordering an LCN 3034 concealed closer?
Handing is required. The 3034 is ordered right hand or left hand, and the default is right hand. Because the closer body sits inside the door leaf, handing is not something you flip in the field the way you can with some surface closers, so get the door swing confirmed before the order goes in.
3) Does the LCN 3034 closer hold the door open, or does it always self-close?
As shipped it self-closes. The standard build is a regular arm with no hold-open, and it is UL/cUL listed for self-closing doors without hold-open. If you need the door to stay parked open, the closer is ordered with the hold-open arm option instead. Pick that at the time of order, since the arm is part of what you are specifying.
4) What spring size should I order on an LCN 3034, and can it be adjusted after install?
The 3034 is offered in spring sizes 1, 2, 3 and 4, and the standard configuration is size 4. Size is chosen off door width and the opening conditions, then trimmed on site: closing power adjusts up to 15 percent, so a size that is close can be dialed in rather than swapped out. Closing speed and latching speed regulate separately, which is what lets you slow the swing without losing the last few inches of latch.
5) Should I use a concealed-in-door closer like the LCN 3034 or a surface mounted closer?
The trade-off is appearance against service access. The 3034 mounts inside the door leaf so nothing shows on the face of the door or the frame, which is why it gets specified in offices, healthcare corridors, schools and retail where the hardware is meant to disappear. The cost is that the door has to be prepped for it, and any future adjustment or replacement means getting back into the leaf. A surface closer needs no door prep and is far easier to retrofit onto an existing opening. If the door is not already prepped for a concealed cylinder, go surface mounted.
6) Can an LCN 3034 concealed closer go on a hollow metal door and a wood door?
It ships with both wood and machine screws, so the fastener pack covers a wood leaf and a metal leaf. The governing condition is not the material but the prep: the leaf has to be 1-3/4 inch and prepped to accept the closer body internally. On a door that has no concealed prep, this is a shop or factory job, not a field install.
7) Will an LCN 3034 closer work in an unheated warehouse or a door that sees cold?
It uses all-weather fluid, so the closing speed stays consistent as temperature swings rather than turning sluggish in the cold and fast in the heat. The regulating screws are tamper resistant, which matters on doors in public corridors where someone will otherwise try to adjust the closer with a screwdriver. Note it is specified as an interior door closer, so use it on interior openings in those buildings, not on the exterior entrance.
8) Does the LCN 3034 closer have a delayed action option for accessible openings?
No delay function on the 3034. The two speeds you control are general closing speed and latching speed, adjusted independently. If your application calls for a door that pauses before it starts to close, this closer will not give you that and you need a closer built with delayed action.
9) Is the LCN 3034 door closer Buy American Act compliant for a government job?
Yes, the 3034 is BAA qualified, which is what a federal, municipal or other publicly funded specification usually asks for. It is a commercial grade closer certified to ANSI/BHMA A156.4 Grade 1 with cast iron construction, which is the other half of what typically appears on that kind of spec.
10) I need to standardize closers across a building. Can the LCN 3034 cover doors of different widths?
Within limits. One model covers interior leaves up to 4 feet wide, and you select spring size 1 through 4 per opening, with 15 percent adjustment on top of that to fine tune each door once hung. So you can standardize on the 3034 and the same finish across a floor and vary only the spring size. Any interior door wider than 4 feet, or an exterior opening, falls outside it and needs a different closer.
11) What finishes does the LCN 3034 concealed closer come in?
Six powder coat finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. Since the closer is concealed in the leaf, the finish you are matching is the exposed arm at the head of the door, so pick against the other door hardware on that opening rather than against the door itself. 689 and 695 are the two that most often match existing commercial openings.
