LCN 4030-61-689 – Frequently Asked Questions

1) What does the LCN 4030-61 blade stop spacer actually do on a parallel arm closer installation?
It drops the parallel arm shoe down so the arm clears a 1/2 inch (13 mm) blade stop on the frame. On frames with a deep stop, the shoe fouls the stop and the arm binds or will not mount flat. The spacer also takes up uneven mounting surface so the shoe sits square. It is an installation accessory for LCN 4030 Series closers, not a replacement arm.
2) Do I need a blade stop spacer, or will my LCN parallel arm mount without one?
Measure the blade stop on your frame. If the stop projects about 1/2 inch, the parallel arm shoe needs the 4030-61 spacer to clear it. Frames with a shallow stop, or closers mounted regular arm on the pull side, do not need it. This is a parallel arm mounting problem only.
3) Is there an equivalent to the LCN 4030-61 blade stop spacer from another closer brand?
No direct one-for-one part matches it. The LCN 4030-61 is an installation accessory built for LCN 4030 Series closers, lowering the parallel arm shoe to clear a 1/2 inch (13 mm) blade stop and compensating for uneven mounting surfaces. The closest accessory offering from another brand is the Cal-Royal 900 Series door closer accessories kit, which serves Cal-Royal 900 Series closers rather than LCN bodies. Because spacers and shoes are sized to the closer's own arm geometry, match the accessory to the closer family already on the door.
4) My door has a deep stop and a parallel arm closer that will not clear it. Do I need a different arm instead of a spacer?
Two different fixes. The LCN 4030-61 spacer keeps the existing parallel arm and lowers the shoe enough to clear a 1/2 inch (13 mm) blade stop, so the closer and arm you already have stay in place. Changing the arm itself is the other route: the Deltana DCCA4041 is a cushion arm for the DC40 closer and the Deltana DCHA1050 is a hold open arm for the DC10 closer, both of which change closer function as well as geometry and only fit their own Deltana closer series. If the closer is an LCN 4030 and the only problem is stop depth, the spacer addresses it without touching arm function.
5) Will the 4030-61 spacer fit LCN closers other than the 4030 Series?
The 4030-61 is specified for LCN 4030 Series closers. Fit on other LCN families is not something to assume from the part number, so match the spacer to a 4030 body. The finish shown is 689, aluminum, which is the usual match to a 689 closer.
6) Does adding a blade stop spacer affect ADA compliance on the opening?
No. The spacer is an ADA compliant accessory and is used to get the closer arm mounted correctly, which is what lets the closer deliver its opening force and closing speed properly. It is listed for commercial use, the environment where ADA opening force limits apply.
7) My door closer arm won't hold the door open - will a blade stop spacer fix that?
No. The 4030-61 is a clearance and mounting shim, nothing more. Hold-open is a function of the arm itself, so you want a hold open arm, like the Deltana DCHA1050 for DC10 closers, or a cushion arm such as the Deltana DCCA4041 for DC40 closers where you need a stop at the arm. Buying the spacer will not change how the door behaves.
8) Is a blade stop spacer the same thing as an offset bottom arm for a floor closer?
Different parts for different systems. The 4030-61 spacer shims a surface mounted parallel arm closer shoe on the frame. An offset bottom arm, like the Dorma 15323 1-1/2 inch offset bottom arm with cover, is for an offset pivot or floor closer setup where the arm has to reach the door from below. If your closer is in the floor, such as a Norton Rixson 28 Series center hung closer, the spacer does not apply at all.
9) Would a Dorma offset bottom arm do the same job as the LCN 4030-61 spacer?
No. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part used at the bottom of a pivoted door, and it carries no fire rating. The LCN 4030-61 is a spacer that mounts at the closer's parallel arm shoe on an overhead LCN 4030 Series closer to gain 1/2 inch of blade stop clearance. Different position on the door and different closer type, so one does not stand in for the other.
10) Is the LCN 4030-61 spacer suitable for a heavy traffic entrance in a school or hospital?
Yes, it is a commercial grade part and LCN lists it for institutional settings including educational and healthcare facilities, offices, retail, and government buildings. Bear in mind it only solves the blade stop clearance on a surface closer. Very heavy traffic entrances on center hung doors are usually handled by a floor closer instead, such as the Norton Rixson 28 Series rated to 350 lb door weight or the 328 Series at 325 lb.
11) For standardizing a building on one closer accessory, is the Cal-Royal 900 kit a broader buy than the single LCN 4030-61 part?
They are scoped differently. The Cal-Royal 900 Series accessories kit is a kit assembled for Cal-Royal 900 Series commercial door controls, so it covers a range of accessory needs within that closer family. The LCN 4030-61 is a single purpose installation accessory for LCN 4030 Series closers, supplying 1/2 inch (13 mm) of blade stop clearance at the parallel arm shoe. If the facility's closers are LCN 4030 Series, the 4030-61 is the part that fits them; a Cal-Royal kit standardizes only the openings running Cal-Royal 900 Series bodies.
