LCN 4020-3077L 689 – Frequently Asked Questions

1) What is the LCN 4020-3077L long arm used for?
The LCN 4020-3077L is a long arm assembly designed specifically for LCN 4020 series door closers. It provides extended reach for doors that require greater opening angles or clearance from the door frame.
2) Which LCN door closers is this long arm compatible with?
This long arm is compatible exclusively with LCN 4020 series door closers. It will not fit other LCN models or different manufacturer door closers. Verify your closer model before ordering.
3) What does the "L" designation mean in the model number?
The "L" indicates this is a left-hand arm assembly. The arm is configured for doors that swing to the left when viewed from the pull side. Ensure proper handing before installation.
4) What finish options are available for this long arm?
LCN long arms typically come in standard architectural finishes including aluminum, dark bronze, and black. Check the specific finish code when ordering to match your existing door closer finish.
5) Does using a long arm affect the door closer's power rating?
The long arm does not change the door closer's power rating or holding force. The LCN 4020 series maintains its original performance specifications when fitted with the long arm assembly.
6) Are there any code compliance considerations with long arms?
Long arms may affect door opening force and closing speed. Verify that the installation meets ADA requirements for opening force and allows proper door positioning for egress codes. Test after installation.
7) What components are included with the long arm assembly?
The assembly typically includes the extended arm, connecting hardware, and mounting brackets. Installation hardware may vary. Check the package contents against the installation instructions upon delivery.
8) How difficult is it to install this long arm replacement?
Installation requires removing the existing arm assembly and mounting the new long arm. Use proper tools and follow LCN installation templates. Door closer adjustment may be needed after installation.
9) Will the long arm require different maintenance procedures?
Maintenance remains the same as standard arms. Check mounting screws periodically and lubricate pivot points as recommended. The extended reach may require more frequent inspection of connection points.
10) Are there right-hand versions of this long arm available?
Yes, LCN produces right-hand long arms for the 4020 series with different model numbers. Ensure you select the correct handing for your door swing direction before ordering.
11) What door weight and width limits apply with the long arm?
The long arm maintains the same door weight capacity as the base 4020 closer. However, verify door dimensions against LCN specifications as the extended reach may affect performance on very wide doors.
12) When would you choose a long arm over a standard arm?
Choose long arms when doors need to open wider than 90 degrees, when frame conditions require extended reach, or when clearance issues prevent standard arm installation. Assess your specific application needs.
