Handing matters here. The 9530-3077PLCM standard arm with track is ordered as either LH (left hand) or RH (right hand), because the 9530 Senior Swing operator itself is a handed product. Order the arm to match the swing of the operator already on the opening.

No. A complete 9530 Senior Swing operator ships with the motor gearbox, control box, standard arm, header and mounting hardware. The 9530-3077PLCM arm is what you buy when you are replacing a damaged arm or track on an operator already installed. Actuators, note, are always a separate purchase.

Only the LCN 9530 power operator. This is an installation accessory for an electromechanical Senior Swing unit, not a closer arm. If you need a replacement arm for a manual surface closer, look at parts built for that closer family, such as the Deltana DCHA1050 hold open arm for the DC10 closer or the Deltana DCCA4041 cushion arm for the DC40.

No. The 9530-3077PLCM is a standard arm with track for the LCN 9530 Senior Swing electromechanical operator, a surface mounted single door power operator that opens automatically and also works in manual mode. The Deltana DCHA1050 is a hold open arm built for the Deltana DC10 door closer, a manual closer, so it has no relationship to the 9530 motor gearbox and header. If the goal is a mechanical hold open on a manual closer, the DCHA1050 addresses that; if the door is a powered ADA operator, the arm has to be the operator's own arm and track.

It's the linkage between the 9530 Senior Swing operator's motor gearbox and the door. The track-style standard arm lets the operator drive the door open under power for accessible entry while still allowing normal manual push-pull operation the rest of the time.

The 9530 operator is a single door, surface mounted unit, and one arm drives one leaf. A pair of doors with a double door header (available 49 inches up to 98 inches) runs two operators, so you need an arm per leaf, handed correctly for each.

Header length and arm are separate decisions. 36 inches is the standard 9530 header, specified anywhere from 33 to 49 inches on a single door, and the 3077PLCM standard arm with track mounts to the operator regardless of how the header was cut. What you do have to match is handing.

They serve different classes of door control. The 9530-3077PLCM is the standard arm and track for LCN's 9530 Senior Swing power operator, which ships as an operator package with motor gearbox, control box, arm, header and mounting hardware, and is a handed product. The Deltana DCCA4041 is a cushion arm for the Deltana DC40 door closer, a manual surface closer accessory used to cushion the door at the end of its opening swing. The LCN arm transmits motion from a powered operator; the Deltana arm is a replacement linkage on a spring closer.

No. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty component used at the bottom of an offset pivot or floor closer door and carrying no fire rating. The LCN 9530-3077PLCM is the standard arm with track for the 9530 Senior Swing operator, mounted at the header on a surface mounted power operator and supplied left hand or right hand to match the door. They mount in different locations and belong to different door control systems.

No. The Cal-Royal 900 Series accessories kit is for Cal-Royal 900 Series commercial door closers, which are manual surface closers. The LCN 9530 Senior Swing operator takes its own handed standard arm with track, ordered left hand or right hand in 689 aluminum, and the operator itself ships with motor gearbox, control box, header and mounting hardware. Arms and accessories from a manual closer line do not interchange with the 9530 track system.

Hold open is not an arm function. The 9530 Senior Swing has an adjustable hold open period of 2 to 32 seconds in either automatic or manual mode, set at the operator's controls, so swapping the arm and track will not affect it.

The 9530-3077PLCM is a commercial-rated part, used on Senior Swing operators specified for ADA accessible entrances. ADA compliance on the 9530 applies in power mode.
