LCN 9540-18 628 36 – Frequently Asked Questions

1) What is the LCN 9540-18 top rail drop plate actually for?
The 9540-18 is a top rail drop plate used with the dress plate on LCN 9540 Series door controls. It is a mounting and alignment accessory, not the door control itself and not the operator arm. It carries the dress plate along the top rail so the installation finishes flush and covers the mounting run.
2) What lengths does the LCN 9540-18 drop plate come in?
Six lengths are offered: 36, 40, 42, 51.5, 69 and 76 inches. Measure the top rail run the dress plate has to cover on your opening and pick the length that matches it, since the plate is cut to that run rather than field trimmed to fit.
3) Will the 9540-18 drop plate work on a door closer other than an LCN 9540?
No. The 9540-18 drop plate is built for the LCN 9540 Series and its dress plate. Accessories for other closers are series specific in the same way, for example the Deltana DCHA1050 hold open arm fits the DC10 and the Deltana DCCA4041 cushion arm fits the DC40. Match the accessory to the closer series already on the door.
4) The head has no room for a surface closer and dress plate at the top rail - what should be specified instead of an LCN 9540-18 drop plate?
Move the closer to the floor and the top rail hardware stops being part of the equation. The Norton Rixson 28 Series is a center hung single acting heavy duty floor closer rated Grade 1 for 350 lb doors, the 328 Series is a center hung single acting heavy duty Grade 1 floor closer at 325 lb, and the 30 Series is a center hung double acting heavy duty Grade 1 floor closer at 200 lb. The Norton Rixson 40 Series is a heavy duty Grade 1 center hung floor closer with cement case rated to 300 lb. All of these are cased in the floor, so they need a floor pocket or cement case poured or cut in, which is a construction decision rather than a hardware swap. The LCN 9540-18 top rail drop plate applies only where a 9540 Series door control is mounted at the head with a dress plate.
5) Is there a direct cross-brand equivalent to the LCN 9540-18 top rail drop plate?
No comparable part matches it. The LCN 9540-18 is a top rail drop plate used with a dress plate on 9540 Series door controls, sold in 628 aluminum anodized and 710 dark bronze anodized in lengths from 36 inches to 76 inches. The nearest accessory-level items carried alongside it are series-locked to other closers: the Cal-Royal 900 Series Door Closer Accessories Kit is built for Cal-Royal 900 Series closers, and the Deltana DCCA4041 cushion arm is built for the Deltana DC40 closer. Neither is a top rail drop plate and neither fits a 9540 Series opening, so order the 9540-18 in the length that matches the rail run.
6) Can I get the 9540 top rail drop plate in dark bronze to match my storefront?
Yes. Two anodized finishes are made: 628 aluminum anodized and 710 dark bronze anodized. Both are offered in every length, 36, 40, 42, 51.5, 69 and 76 inches, so a dark bronze storefront run can be matched at any of those sizes.
7) Do I need to order the dress plate separately from the 9540-18 drop plate?
Yes, they are separate line items. The 9540-18 is the drop plate that the dress plate works with, so a complete top rail installation needs both. Order the drop plate in the length that matches your top rail run and in the finish, 628 aluminum or 710 dark bronze, that matches the rest of the hardware.
8) Is the 9540-18 a closer arm or a mounting plate?
A mounting plate. The 9540-18 provides the attachment and alignment surface at the top rail; it does not move the door. Arms are a different part entirely, like the Dorma 15323 1-1/2 inch offset bottom arm with cover, which is a standard duty arm. If your 9540 needs an arm rather than a plate, the drop plate is not the part.
9) Can a Deltana DCCA4041 or DCHA1050 arm be used instead of an LCN 9540-18 drop plate?
No. The Deltana DCCA4041 is a cushion arm for the DC40 door closer and the Deltana DCHA1050 is a hold open arm for the DC10 door closer, so both are linkage parts that connect a closer body to the door or frame and both are tied to a Deltana closer series. The LCN 9540-18 is a top rail drop plate for 9540 Series door controls, used with a dress plate to carry the mounting and give the run a finished face in lengths of 36, 40, 42, 51.5, 69 and 76 inches. A drop plate solves a mounting surface problem; an arm changes how the closer swings the door. If the requirement is hold open, that is an arm decision on a Deltana closer, not something a drop plate provides.
10) The Dorma 15323 offset bottom arm came up in a search for door control mounting parts - is it an alternative to the LCN 9540-18?
It is a different part for a different point on the door. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty component that works at the bottom of the door and is not fire rated. The LCN 9540-18 is a top rail drop plate for 9540 Series door controls, mounted at the top rail and used with a dress plate, in 628 aluminum anodized or 710 dark bronze anodized. If the takeoff calls for a bottom arm on an offset pivot opening, the 15323 is the shape of part being asked for; if it calls for drop plate support behind a dress plate at the head, that is the 9540-18 in the length matching the rail.
11) Is the LCN 9540 drop plate rated for commercial traffic, or is it a light duty part?
Commercial. LCN classifies the 9540-18 drop plate as a commercial door hardware component, and it is specified in office buildings, schools, hospitals, retail, warehouses, multi tenant residential and government facilities. For a property manager standardizing a building, the same plate in one finish across every 9540 opening keeps the look consistent.
12) For standardizing door control accessories across a facility, does an LCN 9540-18 drop plate cover openings running other closer brands?
It does not carry across brands. The LCN 9540-18 is a commercial top rail drop plate specific to 9540 Series door controls and used with a dress plate, offered in 628 aluminum anodized and 710 dark bronze anodized across 36, 40, 42, 51.5, 69 and 76 inch lengths, which is what makes it standardizable across a run of 9540 openings and across two finish schedules. Openings on other closers take their own accessories: Cal-Royal 900 Series closers take the Cal-Royal 900 Series accessories kit, a Deltana DC40 takes the DCCA4041 cushion arm, and a Deltana DC10 takes the DCHA1050 hold open arm. Standardize by closer series first, then hold one drop plate length and finish per opening size within the 9540 group.
