LCN 4111-307DEL RH 689 – Frequently Asked Questions
1) Will the LCN 4111-3071DEL cylinder assembly fit any LCN closer, or only the 4110 Series?
Only the 4110 Series. The 4111-3071DEL is the delayed action cylinder assembly built for LCN 4110 Series closers, so it is a repair part for that body and not a universal cylinder. If the closer on the door is a different LCN family, the cylinder from this series will not drop in. Read the model stamped on the closer body before ordering.
2) Does the LCN delayed action cylinder assembly have to be ordered left hand or right hand?
Handing is required. The 4111-3071DEL cylinder assembly is handed and is ordered as either LH left hand or RH right hand, so the wrong hand is the most common way this part gets returned. Stand outside the door on the side it swings away from: hinges on the left is left hand, hinges on the right is right hand. Match the hand to the closer already mounted, not to the door you wish you had.
3) What does the delayed action cylinder actually do on a door closer?
Delayed action holds the door open near its full swing for a period before the normal closing cycle starts. That extra dwell is what lets someone in a wheelchair, pushing a cart, or carrying a load clear the opening before the door begins to close. The 4111-3071DEL is the cylinder that provides that function on a 4110 Series closer, and it is listed as ADA compliant in operation.
4) Can I repair an LCN 4110 closer with a bad delayed action instead of replacing the whole closer?
That is exactly what this part is for. The 4111-3071DEL is a replacement cylinder assembly for 4110 Series closers, so a unit whose delay has quit or whose cylinder is leaking can be rebuilt on the door rather than pulled and replaced. Reusing the existing arm, shoe, and mounting holes also means no new prep in the door or frame.
5) What finishes does the LCN 4111-3071DEL cylinder assembly come in?
Six finishes, in both hands: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. For a repair on an existing door, match the number on the closer cover rather than guessing from the look, since 690, 691, and 695 all read as bronze from across a lobby but do not match side by side.
6) Is this LCN cylinder assembly rated for a high traffic commercial opening?
Built for commercial duty. LCN rates the 4110 Series delayed action cylinder assembly to ANSI/BHMA Grade 1, the heavy duty tier, and it is classified for commercial rather than residential use. That covers the openings these get put on: office lobbies, schools, hospitals, retail entries, and multi-tenant residential corridors.
7) I have a dozen LCN 4110 closers in the building. Can I stock one cylinder assembly for all of them?
Not one, but two covers a fleet. Because the 4111-3071DEL is handed, a building with doors swinging both ways needs an LH and an RH on the shelf. Finish is the other split: if the openings were originally specified in the same finish, one finish code covers them all, so a facility standardized on 689 aluminum only stocks two part numbers total.
8) Does swapping in a delayed action cylinder change how fast the door closes?
Delay and closing speed are separate. The delayed action cylinder adds a dwell at the wide open position; the sweep and latch speeds are still set at the closer's own valves after the part is in. Expect to re-adjust those valves once the 4111-3071DEL is installed, because a door that dwells correctly but slams on the latch still fails an accessibility walkthrough.
