LCN 4000T-3034 – Frequently Asked Questions
1) What does the LCN 4000T-3034 track roller actually do, and where does it go?
The 4000T-3034 is the roller that rides inside the track on an LCN 4000T Series hold-open track arm closer. The arm's roller travels the track as the door swings, and it is the piece that engages the hold-open. It's a service part, not a complete closer, so it replaces a worn roller on a closer already hung on the door rather than being a standalone door control.
2) Will an LCN 4000T track roller fit my LCN 4040 or other regular-arm closer?
No. The 4000T-3034 roller is made for LCN 4000T Series track arm closers only. A regular arm or parallel arm closer has no track for the roller to ride in, so there is nothing for this part to fit. Look at the arm on the door first: if it is a straight arm running into an aluminum track mounted on the door or frame face, you have a track arm and this is the right family. If the arm has two jointed links and no track, this part will not go on it.
3) My door closer stopped holding open, do I need a whole new closer or just the roller?
On a 4000T track arm closer, a hold-open that stopped catching or that drags and chatters through the track is usually the roller, not the closer body. The 4000T-3034 is sold as a replacement part for exactly that repair, so you can rebuild the hold-open function without pulling the closer off the door. If the closer itself is leaking oil or has lost closing control, that is a body problem and a roller will not fix it.
4) Is the LCN 4000T track roller a genuine LCN part or an aftermarket copy?
Genuine LCN. The 4000T-3034 is factory LCN hardware built to the original equipment fit for the 4000T track, which matters on a track arm because a roller that is even slightly off diameter binds in the channel instead of rolling. For a property manager standardizing a building on LCN, ordering by the LCN model number keeps every opening on the same part.
5) Does replacing the track roller affect ADA compliance on the opening?
The 4000T-3034 is an ADA compliant component, so putting the correct roller back in a 4000T track arm keeps the opening on spec. That matters most in schools, healthcare and government buildings, where a closer that binds in the track can push opening force past what the facility was signed off at. Anyone doing MRO work in those facilities should be replacing a worn roller rather than running it out.
6) How do I order the right LCN track roller, is there a handing or finish to specify?
One part number covers it: 4000T-3034. There is no handing, size or finish choice to make on the roller, so there is nothing else to specify beyond confirming your closer is a 4000T track arm. For a maintenance shop carrying spares across a portfolio of 4000T openings, that means a single line item stocks every door.
7) Is this LCN track roller rated for commercial traffic or is it a light duty part?
Commercial. The 4000T-3034 is specified for commercial door control service, which is where track arm closers earn their keep, on office entries, classroom and corridor doors, hospital corridors, retail, and multi-tenant residential common doors. It is not a residential-grade part and there is no lighter version of it.
8) Should I stock LCN track rollers as a spare, or only order when one fails?
Track rollers are a wear item on a hold-open closer, and a worn roller grinds the track it runs in, so a failed roller left in service turns a small part into a track and arm replacement. The 4000T-3034 is sold for preventive replacement as much as for breakdown repair. On a portfolio with a lot of 4000T openings, keeping a few on the shelf is the cheaper side of that trade.
