LCN 4050A-61 689 – Frequently Asked Questions

1) What does the LCN 4050A-61 spacer actually do on a parallel arm closer installation?
The 4050A-61 is a blade stop spacer that drops the parallel arm shoe down so it clears a 1/2 inch (13 mm) blade stop on the frame. Without it, the shoe fouls the stop and the arm cannot sit flat or travel correctly. It also takes up uneven mounting surface behind the shoe so the closer sits true.
2) I have a 1/2 inch blade stop on my frame - do I need this spacer or can I mount the closer without it?
With a 1/2 inch blade stop and a parallel arm mount, the spacer is required. It is the part that lowers the shoe past the 13 mm stop. If your frame has no blade stop, or you are mounting the closer regular arm or top jamb, you do not need it.
3) Will the 4050A-61 blade stop spacer work with any LCN closer?
It is built for the LCN 4050A Series door closers. Fit is specific to that series' parallel arm shoe, so use the spacer matched to whichever closer series you actually have rather than assuming a shim from another family will line up.
4) What finishes does the LCN blade stop spacer come in so it matches my closer?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Order the spacer in the same finish code as the closer body and arm, since the spacer sits in plain view under the parallel arm shoe.
5) My closer arm shoe rocks because the frame face is not flat - will this spacer fix that?
That is one of its two jobs. The 4050A-61 compensates for uneven mounting surfaces so the shoe seats flat and the arm stays in proper alignment. It is a common fix on older hollow metal frames where the stop face is not true.
6) Is the 4050A-61 spacer suitable for commercial openings and ADA accessible doors?
Yes on both counts. LCN lists it as a commercial-duty part and as ADA compliant, so adding it to a parallel arm installation does not take the opening out of compliance. It is used in offices, schools, healthcare, retail, industrial, multi-tenant residential and government buildings.
