LCN 4040XPT-3034 – Frequently Asked Questions

1) Will the LCN 4040XPT-3034 roller fit my LCN 4040 or 4040XP closer, or only the XPT?
Only the 4040XPT. The 3034 roller is built for the XPT track arm, and the XPT is the track version of the 4000 Series, so a 4040 or 4040XP set up with a standard parallel or regular arm has no track for this roller to run in. Check the closer body or the arm on the door: if there is no track mounted across the frame face, this is the wrong part.
2) What is the 1/8 inch shoulder dimension on the LCN 4040XPT track roller and why does it matter?
The shoulder is the step on the roller stud that sets how the roller seats against the arm, and on the 3034 it measures 1/8 inch (3mm). LCN builds this roller in more than one shoulder dimension, so ordering the wrong one gives you a roller that binds in the track or sits loose. Measure the shoulder on the roller you are pulling out before you order.
3) Can a Deltana DCHA1050 hold open arm be used in place of an LCN 4040XPT track roller?
No. The Deltana DCHA1050 is a hold open arm built for the Deltana DC10 door closer, so it is a complete arm assembly matched to that closer body. The LCN 4040XPT-3034 is the roller that travels inside the track of an LCN 4040XPT closer, with a 1/8 inch (3mm) shoulder dimension cut to seat in that track. The two are not interchangeable: one replaces an arm on a DC10, the other rides in an LCN 4040XPT track. If the closer on the door is an LCN 4040XPT, the roller is the part that fits it.
4) Our door is center hung and cannot take an overhead track closer. What should we use instead of an LCN 4040XPT and its track roller?
A center hung opening calls for a floor closer rather than an overhead track assembly, and the LCN 4040XPT-3034 roller only has a job where an LCN 4040XPT track closer is mounted. For single acting center hung doors, the Norton Rixson 28 Series is a heavy duty center hung single acting floor closer rated to 350 lbs door weight, and the Norton Rixson 328 Series is a heavy duty center hung single acting floor closer rated to 325 lbs. For a door that swings both ways, the Norton Rixson 30 Series is a center hung double acting heavy duty floor closer rated to 200 lbs. All three are Grade 1. Size by leaf weight and by whether the door is single or double acting.
5) My LCN closer door is squeaking or chattering when it opens. Does replacing the track roller fix it?
A worn roller is the usual cause of noise and drag in a track closer. The 4040XPT-3034 is a low friction roller assembly, so a fresh one takes the grinding and chatter out of the swing. Pull the arm and spin the old roller by hand first: if it is flat-spotted, gritty, or seized, the roller is your problem. If the track itself is scored or bent, the roller alone will not cure it.
6) Does swapping the roller on an LCN 4040XPT affect the ADA opening force on the door?
No. The 4040XPT-3034 roller is an ADA compliant component in an ADA closer application, and it carries no spring or valve, so it does not change closing force or sweep speed. Those are set at the closer body. A binding old roller can add friction that pushes opening force out of range, so a fresh roller keeps the door at whatever the closer is adjusted to.
7) I have a Deltana or Dorma closer that needs a new arm part. Is this LCN roller a substitute?
No, and there is no cross-brand equivalent for a track roller. Closer arms and tracks are brand and series specific. For a Deltana DC10 you would order the DCHA1050 hold open arm; for a Deltana DC40, the DCCA4041 cushion arm; for a Dorma application, the 15323 1-1/2 inch offset bottom arm with cover. Cal-Royal sells a 900 Series accessories kit for its own closers. Match the part to the closer brand and series stamped on the body.
8) Can I standardize on one LCN track roller across all the 4040XPT closers in my building?
Yes, provided every closer is a 4040XPT with a hold open track and the same 1/8 inch shoulder roller. That is the point of stocking the 3034 as an MRO spare: one part number covers the fleet, and a maintenance tech can swap a noisy door in minutes without pulling the closer. Verify the shoulder dimension on a sample of your existing rollers before buying quantity, since LCN builds this roller in more than one shoulder size.
9) What is the difference between the Deltana DCCA4041 cushion arm and an LCN 4040XPT track roller?
The Deltana DCCA4041 is a cushion arm for the Deltana DC40 door closer -- a swinging arm linkage that absorbs the door at the end of its opening swing. The LCN 4040XPT-3034 is a track roller, the low friction rolling element that carries the closer arm along the track of an LCN 4040XPT and lets it hold open. They solve the stop-and-hold problem in different closer architectures, and the roller is dimensioned with a 1/8 inch (3mm) shoulder specifically for the LCN 4040XPT. Match the part to the closer already mounted on the door rather than to the function name.
10) Will a Dorma 15323 offset bottom arm work with an LCN 4040XPT closer track?
No. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part that connects a pivoted or floor-mounted closer to the bottom of the door leaf. It is not fire rated. The LCN 4040XPT-3034 is a hold open track roller for the LCN 4040XPT overhead closer, a commercial-grade component with a 1/8 inch (3mm) shoulder dimension sized to that track. An offset bottom arm and a track roller sit at opposite ends of the door and belong to different closer systems, so one cannot stand in for the other.
11) Is the LCN 4040XPT track roller rated for high traffic commercial doors, or is it a light duty part?
Commercial duty. The 3034 roller is a commercial grade part, and the 4040XPT is LCN's heavy duty track closer used on office entrances, schools, hospitals, retail, warehouses, apartment buildings and municipal facilities. It is not a residential closer part.
