Product Description
LCN 4011 Cylinder Assembly in Aluminum
Replacement Cylinder Assembly for the LCN 4011 Series commercial door closer. Genuine LCN OEM part — matches factory specifications for fit and performance. If your 4011 closer needs a new Cylinder Assembly, this is the correct part.
Pro-Tip from Our Locksmiths: On LCN closers, the cover and screws are cosmetic — the closer works fine without them. But if you're in a finished space, order the cover in the matching finish to keep it looking professional.
