LCN 3033-652 – Frequently Asked Questions

1) Will the LCN 3033 concealed closer work on a 1-3/4 inch interior door that's 4 feet wide?
That's exactly the opening the 3033 is built for. It's a concealed-in-the-door closer for 1-3/4 inch interior doors up to 4'0" wide, and it's a size 3 closer, so the spring power is fixed rather than adjustable across a range. Wider than 4'0", or an exterior opening, and you're outside what the 3033 covers.
2) Does the LCN 3033 mount in the door or in the frame?
In the door. The 3033 is concealed in the door leaf itself, with the double lever arm reaching to the frame, so the door has to be prepped (or come factory prepped) for the closer body. If your doors are already hung and unprepped, an overhead concealed-in-frame closer or a surface mounted closer is the less invasive route.
3) Do I have to specify handing when ordering the LCN 3033 concealed closer?
Yes, handing is a required choice. The 3033 is ordered right hand or left hand, and a concealed-in-door closer can't be flipped in the field the way many surface closers can, so get the hand right off the door schedule before you order.
4) Is the LCN 3033 concealed closer rated for a commercial building, and how tough is the internal build?
It's a commercial closer, ANSI/BHMA A156.4 Grade 1 certified and UL/cUL listed for self-closing doors. Inside is a cast iron cylinder with a 1-1/8 inch forged steel piston running on a full-complement bearing. For a school corridor, office suite or multi-family common door, that's the class of closer specifiers expect.
5) Concealed closer or surface mounted closer for an office corridor door?
A concealed unit like the 3033 hides in the door leaf, so nothing shows above the opening except the arm, which is why it gets specified in lobbies and finished corridors. The trade is access: adjusting or servicing it means getting at the closer in the door, and the door must be prepped for it. A surface mounted closer is the cheaper, faster answer on an existing unprepped door and is far easier to swap later. Choose concealed when appearance drives the spec, surface when serviceability or retrofit does.
6) Can I get the LCN 3033 with a hold open arm?
Arm choice is part of the order. The 3033 ships with a regular arm by default, and a hold open arm is the alternative if you want the door to stand open at a set point. Pick one at the time of order, since the arm is matched to the concealed body.
7) Does the LCN 3033 have delayed action for slow closing?
No delay function on the 3033. What you do get is separate adjustment of the general closing speed and the latching speed, which covers most complaints about a door slamming or not pulling shut the last few inches. If you specifically need a hold-back delay for accessible traffic, this isn't the closer for it.
8) What finishes does the LCN 3033 plated closer come in, and what actually gets plated?
Six plated finishes: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome. On a concealed closer the body is buried in the door, so the plating is on the arm and the exposed fasteners. That's the part that has to match your levers and hinges.
9) Will an LCN 3033 keep working in an unheated warehouse or a door that sees temperature swings?
The 3033 uses all-weather fluid, so the closing speed holds steadier as temperature moves instead of going sluggish when it's cold and fast when it's hot. The speed regulating screws are tamper resistant too, which matters on a door the public can reach.
10) Does the LCN 3033 come with mounting screws, and can I install it in a wood door?
Both wood and machine screws are supplied with the 3033, so it covers a wood door or a hollow metal door prepped for the concealed body. What isn't in the box is the door prep itself: the leaf has to be routed for the closer per LCN's template before anything goes in.
11) Is the LCN 3033 Buy American compliant for a federal or municipal job?
Yes, the 3033 is BAA qualified, which is the box that has to be ticked on federal and many state or municipal projects. That plus Grade 1 certification is usually what a government spec is asking for on a concealed closer.
