LCN 4050A-31 – Frequently Asked Questions

1) What is the LCN 4050A-31 and what does it do?
The 4050A-31 is the cover screw for LCN 4050A Series door closers. It is the fastener that holds the closer's cover onto the body, sold as a replacement part rather than a complete closer. If you are chasing a rattling or missing cover on a 4050A, this is the piece you order.
2) Will the 4050A-31 cover screw fit door closers other than the LCN 4050A Series?
It is made for the LCN 4050A Series specifically. Thread and length are matched to that closer family, so treat it as a 4050A part only. For a different LCN series, order the cover screw listed under that series instead of substituting this one.
3) Does replacing the cover screw on an LCN 4050A affect ADA compliance of the opening?
No. The 4050A-31 is listed as ADA compliant, so using the correct factory cover screw keeps the closer assembly as specified. ADA opening force is set by the closer's own adjustment, not by the cover hardware, so reinstall the cover screw and verify your closer settings as usual.
4) I just need the closer cover back on, do I get the cover with this part?
No, the 4050A-31 is the screw only. If the cover itself is damaged or missing, you need to order the 4050A cover separately; this part is the installation fastener that secures it.
5) Is the LCN 4050A-31 cover screw rated for commercial use or is it a residential part?
Commercial. It is catalogued as a commercial door hardware component, intended for the kind of high traffic openings 4050A closers get hung on: offices, schools, hospitals, retail, warehouses, and government buildings.
6) For a property manager standardizing LCN 4050A closers across a building, is it worth stocking cover screws?
Yes, if your openings are all 4050A. Cover screws are the piece that walks off during maintenance or gets dropped in the hallway, and one part number covers every 4050A closer in the fleet. Keeping a few 4050A-31 screws on the MRO shelf means a loose cover gets fixed on the same trip instead of waiting on an order.
