LCN 4031T-3071 695 – Frequently Asked Questions

1) Will the LCN 4031T-3071 cylinder assembly work on a left-hand door, or do I have to order handed?
Handing is not a factor. The 4031T-3071 cylinder assembly is non-handed, so the same part goes into a 4030T Series closer regardless of which way the door swings. That also means a maintenance shop can stock one part number for every 4030T opening in the building instead of a left and a right.
2) Which LCN door closers does the 4031T-3071 cylinder assembly fit?
It is built for LCN 4030T Series door closers. The cylinder is the body of the closer that holds the hydraulic valving, so it has to match the series it came out of. If the closer on your door is a different LCN family, the 4031T-3071 is not the replacement cylinder for it.
3) Is this a whole door closer or just a replacement part?
This is a replacement component, not a complete closer. The 4031T-3071 is the standard cylinder assembly only, so arms, shoes, brackets and mounting screws are not part of it. If your existing 4030T arm and mounting hardware are in good shape, the cylinder swap is what restores control; if the arm is bent or the shoe is stripped, order those separately.
4) What finishes does the LCN 4031T cylinder assembly come in, and can I match the closers already on my other doors?
Six finishes are offered: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. Those are the standard LCN closer finish numbers, so if you read the finish code off the closer you are servicing you can order the cylinder to match the rest of the openings.
5) If I replace the cylinder on a 4030T closer, will the door still meet ADA opening force requirements?
The 4031T-3071 cylinder assembly is ADA compliant, and because it restores the original 4030T hydraulic control it keeps the closer performing to its original specification. You still have to adjust spring power and sweep on site and verify opening force at the door, since ADA force is a function of the installed adjustment, not the part alone.
6) Is this cylinder assembly suitable for a high-traffic commercial entrance, or is it a residential-grade part?
It is a commercial part. The 4031T-3071 is built to LCN's commercial-grade standard for 4030T closers and is used in office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and government buildings. It is not a light-duty residential closer component.
7) Can a building maintenance tech swap the 4030T cylinder, or does this need a locksmith?
The cylinder assembly is meant to be changed out in the field by a qualified technician, which keeps the door out of service for a short window rather than requiring a full closer replacement. The work is mechanical: pull the arm, remove the closer body, transfer the arm and mounting hardware to the new cylinder, then reset spring power and closing and latching speed before you leave.
