LCN 4020-72 RH 689 – Frequently Asked Questions

1) Will the LCN 4020-72 cover fit any LCN door closer, or only the 4020 Series?
The 4020-72 plastic cover is made for LCN 4020 Series closers only. It is a series-specific part, so it will not fit other LCN closer bodies. Confirm the closer on the door is a 4020 before ordering.
2) Is the LCN 4020-72 closer cover handed, and how do I pick left or right?
Yes, it is handed. The 4020-72 is ordered as LH (left hand) or RH (right hand) to match the swing of the door the closer is mounted on. A left hand cover will not sit correctly on a right hand installation, so the hand has to match the closer as installed, not the adjacent door.
3) Does replacing a cracked cover on a 4020 closer require replacing the whole closer?
No. The 4020-72 is sold on its own as an installation accessory, so a broken or missing cover can be swapped without touching the closer body or the arm. That is the usual repair for vandalized or discolored covers in schools, offices and multi-tenant buildings.
4) What finishes does the LCN 4020-72 plastic cover come in?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. Each is available in both left and right hand. For a building where closers were originally specified in a painted finish, match the number on the existing cover so replacements across a run of openings stay consistent.
5) Is the LCN 4020-72 cover ADA compliant for a barrier-free opening?
Yes, the 4020-72 is listed as ADA compliant, so adding it to a 4020 closer on an accessible opening does not put the door out of compliance. Note that ADA opening force still depends on how the closer itself is adjusted.
6) Is a plastic closer cover durable enough for a school or high-traffic commercial door?
The 4020-72 is rated for commercial rather than residential use and is a commercial-grade plastic cover intended for office buildings, schools, healthcare, retail, industrial and government facilities. In heavy-abuse locations, plan on it as a consumable you restock rather than a permanent part, and keep the finish and hand you use on hand.
7) What exactly does the 4020-72 do on an LCN 4020 closer?
It snaps over the closer body to conceal the mechanism and give the installation a finished look, while shielding the cylinder from dust and casual contact. It is cosmetic and protective; it does not affect closing speed, backcheck or spring power.
