LCN 5012-690 – Frequently Asked Questions

1) Where does the LCN 5012 door closer actually mount - in the door or in the frame?

In the frame. The 5012 is an overhead concealed closer: the cast iron cylinder is concealed in the frame head and a double lever arm is exposed to the door. That means the frame has to be prepped and deep enough to take the cylinder, so it is a decision made at frame order or a frame modification on a retrofit, not a surface swap.

2) Do I have to specify handing when ordering an LCN 5012?

Yes, handing is a required selection. The 5012 is ordered right hand or left hand, with right hand as the default. Determine the swing from the opening before you order, because a concealed-in-frame closer is not something you reverse on site the way you would flip a surface closer.

3) Can I get the LCN 5012 with a hold-open arm?

Yes. The arm is a required choice at order: regular arm (REGARM) is the default, and a hold open arm (H) is available. Note that the Grade 1 UL and cUL listing on the 5012 is stated for self-closing doors without hold-open, so on a fire-rated opening the regular arm is the one to specify.

4) Does the LCN 5012 meet ADA opening force and Grade 1 requirements for a school or hospital?

It does. The 5012 is ANSI/BHMA A156.4 Grade 1 certified, UL and cUL listed for self-closing doors, and meets ADA reduced opening force requirements. It is also BAA qualified, which matters if you are buying on a federal or federally funded project.

5) What is the difference between the standard and delay action cylinder on the LCN 5012?

The cylinder is a required pick. Standard is the cast iron cylinder assembly with mounting plate (CYL). The delay action cylinder (CYLDEL) holds the door near full open briefly before closing, which is what you want in healthcare, schools, or anywhere carts, wheelchairs, or slower traffic need extra time through the opening. Both are the same cast iron body.

6) Can I adjust closing speed and latch speed separately on the LCN 5012?

Yes. The 5012 has separate regulating screws for general closing speed and latching speed, and they are tamper-resistant, so a tenant or student cannot back them off with a screwdriver. Combined with the all-weather fluid, that keeps the adjustment holding through temperature swings on exterior openings.

7) Are mounting screws included with the LCN 5012, or do I need to supply fasteners?

Wood and machine screws are supplied with the 5012. What you still need to confirm is the frame prep: because the cylinder sits concealed in the frame head, the frame must be cut and reinforced per the 5010 Series installation template before the closer goes in.

8) Is a concealed closer like the LCN 5012 the right choice, or should I use a surface closer?

Go concealed when the architect wants nothing on the face of the door and the frame can be prepped for it, which is the normal case on aluminum and hollow metal entrances in institutional and government work. The 5012 puts the cast iron cylinder in the frame head with only the double lever arm showing. If the frame is already installed and not prepped, or you are replacing a closer on an existing opening with no concealed pocket, a surface mounted closer is the practical route since it needs no frame modification.

9) Is the LCN 5012 heavy duty enough for a high-traffic entrance?

It is built for exactly that. Cast iron cylinder with a 1-1/2 inch diameter piston, forged steel main arm, and a full-complement low-friction bearing, rated Grade 1 and classed as heavy duty commercial. Typical placements are school and hospital corridors, municipal buildings, industrial facilities, and multi-tenant residential entrances.

10) What finishes does the LCN 5012 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 only the double lever arm is visible once the cylinder is in the frame, pick the finish to match the arm to your existing door hardware across the building.
