LCN 9550-18 75-1/2 628 – Frequently Asked Questions

1) What lengths does the LCN 9550-18 mounting plate come in?
Four lengths are offered on the 9550-18 mounting plate: 75-1/2 inches, 76 inches, 87-1/2 inches and 91-1/2 inches. The length you need follows the opening the 9550 Series closer is going onto, so measure the head condition on the frame before picking one. All four are supplied in 628 aluminum anodized.
2) Will the LCN 9550-18 mounting plate work with a door closer from another LCN series?
No. The 9550-18 plate is built for LCN 9550 Series closers only. Mounting a different series onto it means the hole pattern and alignment are not the ones the plate was cut for. If the closer on your door is not a 9550, order the plate that matches that series instead.
3) The door is center hung and the closer is going in the floor - does the LCN 9550-18 plate still apply?
No. The LCN 9550-18 is a mounting plate for LCN 9550 Series overhead door closers used in commercial installations, so it belongs to an opening where the closer mounts at the head. For a center hung door with a floor closer, the hardware is a different assembly: the Norton Rixson 28 Series is a Grade 1 heavy duty center hung single acting floor closer rated to 350 lbs door weight, the Norton Rixson 328 Series is a Grade 1 heavy duty center hung single acting floor closer rated to 325 lbs, and the Norton Rixson 30 Series is a Grade 1 heavy duty center hung double acting floor closer rated to 200 lbs door weight. A floor closer is set in the floor at the pivot point and takes a cement case rather than a head-mounted plate.
4) Can a Deltana DCCA4041 or DCHA1050 arm be used in place of an LCN 9550-18 mounting plate?
No, those are different parts of a closer installation. The LCN 9550-18 is a mounting plate for LCN 9550 Series door closers, supplied in lengths of 75-1/2 inch, 76 inch, 87-1/2 inch and 91-1/2 inch in 628 aluminum anodized. The Deltana DCCA4041 is a cushion arm for the Deltana DC40 door closer and the Deltana DCHA1050 is a hold open arm for the Deltana DC10 door closer. An arm connects the closer body to the door or frame and controls the swing; the 9550-18 plate is the mounting surface the closer is fastened to. Ordering an arm when the opening needs a plate leaves the closer with nothing to land on, and both Deltana arms are tied to their own DC10 and DC40 closer bodies rather than to the LCN 9550 Series.
5) What is the equivalent of the LCN 9550-18 mounting plate if the closers on the job are Cal-Royal 900 Series?
Use the Cal-Royal 900 Series Door Closer Accessories Kit, which is the accessory package for Cal-Royal 900 Series commercial door controls. The LCN 9550-18 mounting plate is engineered for LCN 9550 Series closers and is offered in 628 aluminum anodized at 75-1/2 inch, 76 inch, 87-1/2 inch and 91-1/2 inch. Door closer mounting hardware is series-matched on both sides: the 9550-18 is dimensioned to the 9550 closer body, and the Cal-Royal kit is built around the 900 Series. A property manager standardizing a building on one closer family should order the mounting parts from that same family rather than mixing an LCN plate under a Cal-Royal closer.
6) Is the LCN 9550-18 plate rated for heavy commercial traffic?
Grade 1, per BHMA, and it is a commercial-duty part rather than a residential one. That is the top BHMA durability tier, which is what a school, hospital or office corridor door needs when the closer is cycled all day.
7) Do I need a mounting plate when installing an LCN 9550 Series door closer?
A plate is what gives the 9550 closer a flat, correctly drilled surface to fasten to at the head, and it carries the alignment for the unit. Where the frame face is not suitable for direct attachment, the 9550-18 is the accessory that makes the install work. It is an installation accessory, not a closer, so it does not include the closer body or arm.
8) What other door closer accessories can I get if I am not running an LCN 9550?
Depends on the closer. For a Cal-Royal 900 Series closer there is the Cal-Royal 900 Series accessories kit. Deltana surface closers have their own arms, the DCCA4041 cushion arm for the DC40 and the DCHA1050 hold open arm for the DC10. And for a bottom arm on an offset pivot opening, the Dorma 15323 is a 1-1/2 inch offset bottom arm with cover. None of those substitute for the 9550-18 plate; each belongs to its own closer family.
9) Is the Dorma 15323 offset bottom arm an alternative to the LCN 9550-18 mounting plate?
They serve different openings. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part with no fire rating, and a bottom arm attaches a door to a floor closer or pivot at the sill. The LCN 9550-18 is a Grade 1 mounting plate for LCN 9550 Series door closers, built to BHMA Grade 1 for heavy duty commercial door closer applications. An institutional buyer working to a Grade 1 or fire rated schedule should note that the 15323 is stated as standard duty with no fire rating, which is a different specification line than a Grade 1 closer mounting plate.
10) What finish is the LCN 9550 Series mounting plate available in?
628 aluminum anodized is the only finish on the 9550-18 plate, across every length. That is the standard clear anodized aluminum that matches aluminum storefront frames and most 628 closer bodies, so it blends in on a glass front opening rather than standing out.
11) Can I standardize the LCN 9550-18 mounting plate across a whole building?
Yes, and that is the usual reason to buy it in quantity. One finish, 628 aluminum anodized, keeps every opening looking the same, and the four lengths (75-1/2, 76, 87-1/2 and 91-1/2 inches) cover the range of openings a facility typically has. Grade 1 commercial construction is what carries it in office, education, healthcare, retail and municipal buildings where the doors run all day.
