Product Description
LCN 4642 Cylinder Assembly CS in Aluminum
Replacement Cylinder Assembly CS for the LCN 4642 Series commercial door closer. Genuine LCN OEM part — matches factory specifications for fit and performance. If your 4642 closer needs a new Cylinder Assembly CS, this is the correct part.
Pro-Tip from Our Locksmiths: When replacing arms or arm assemblies, check the connecting pins and bushings at the same time. Worn bushings are the real reason most arm replacements happen — the arm is fine, but the pivot is sloppy.
