LCN 4011-3071 RH 689 – Frequently Asked Questions

1) Does the LCN 4011-3071 cylinder assembly have to be ordered handed?
Handing matters on the 4011-3071. It's a handed cylinder assembly, offered LH and RH, so you order to match the door the closer is mounted on. Get it backwards and the part won't perform correctly in the closer body. Confirm the hand of the existing 4010 Series closer before you order, not the hand of the door as you'd call it for a lockset.
2) Will the 4011-3071 cylinder fit any LCN door closer, or only the 4010 Series?
Only the 4010 Series. The 4011-3071 cylinder assembly is built for LCN 4010 Series closers within the 4000 Series family. If the closer on your door is a different LCN model line, this cylinder is the wrong part, so read the cover plate or the body casting for the model before ordering.
3) What is the difference between the standard, CYLDEL and TEL cylinder options on the LCN 4011-3071?
Three builds are offered. Standard Assembly is the plain replacement cylinder. CYLDEL is the delayed action cylinder with adjustable spring size 1 through 6, so one part covers the full spring range and you set closing force in the field. TEL Assembly is the temperature compensated build, which holds closing speed steady as the fluid temperature swings. Pick CYLDEL if you need delay plus spring adjustment, TEL if the opening sees real temperature change (an exterior door, a vestibule, an unconditioned corridor). Each of the three is available in all six finishes and in both hands.
4) I need a door closer that meets ADA opening requirements. Does the LCN 4011-3071 cylinder keep that?
The 4011-3071 is ADA compliant and, in the CYLDEL build, gives you delayed action, which is what lets a slower user clear the opening before the door starts to close. Spring size is adjustable 1 through 6 on that cylinder, so you can dial the closing force down to what your facility's accessibility requirement calls for and back up if the door is fighting stack pressure.
5) My 4010 closer is dropping the door too fast in winter. Will a new cylinder fix that?
That's the classic symptom for a temperature compensated cylinder, and the TEL Assembly build of the 4011-3071 is exactly that part. Hydraulic fluid thins in heat and thickens in cold, which is why an exterior closer that's set right in July slams in January. The TEL cylinder holds closing speed consistent across that temperature swing. Order it in the hand of the closer you're servicing.
6) Do I need to replace the whole LCN 4010 closer, or can I just change the cylinder?
The 4011-3071 is a replacement cylinder assembly, so on a 4010 Series closer whose body and arm are sound you swap the cylinder rather than the whole unit. That's the usual call when the closer is leaking or has lost speed control but the mounting and arm geometry are still good. You do need to match hand and finish to what's on the door.
7) What finishes does the LCN 4011-3071 cylinder assembly come in?
Six: 689 Aluminum, 690 Statuary Bronze, 691 Light Bronze, 693 Gloss Black, 695 Dark Bronze and 696 Brass. If you're servicing one closer in a run of openings, match the finish code stamped on the existing closer cover rather than eyeballing it, since 690, 691 and 695 all read as bronze from across a lobby but do not match side by side.
8) Is the LCN 4011-3071 cylinder suitable for a residential door?
It's a commercial-duty part. The 4011-3071 is built for 4010 Series closers on commercial openings such as offices, schools, healthcare buildings, retail and multi-tenant residential common doors. On a single-family house door it's more closer than the opening needs, and it only helps you at all if there's already an LCN 4010 hanging there.
