Norton Rixson 403000 – Frequently Asked Questions

1) Does the Norton Rixson 40 Series floor closer come with the top pivot, or do I have to order that separately?
The 340 top pivot ships with the 40 Series floor closer, and the package also includes wood and machine screws for the install. What you still have to sort out on site is the floor: the cement case needs an opening cut and routed in the slab, and the header has to be prepped to take the top pivot. Budget for floor prep and templates, not for extra pivot hardware.
2) Will a Norton Rixson 40 Series floor closer hold the door open?
No hold open on the 40 Series floor closer. It closes and centers the door every time, with a centering arm and adjusting screws in the face of the door setting where that center position lands. If your opening needs the leaf parked open, this is the wrong device and you would be looking at a closer with a hold open arm or a hold open track instead, such as the LCN 4040SEH-3038 hold open track or the Deltana DCHA1050 hold open arm for the DC10.
3) Is this floor closer suitable for a high traffic exterior entrance, and will the case survive being buried in a slab?
It is built for exactly that. Grade 1, heavy duty, rated for high traffic commercial use, with a rust-proof cement case and a Cycolac cover. The rust-proof case is the part that matters for an entrance where water tracks in off the sidewalk or the slab stays damp, because the case is what sits in the floor permanently long after the mechanism has been serviced.
4) Will a Dorma 15323 offset bottom arm work in place of the Norton Rixson 403000?
No. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part that connects a door to a closer already in place. The Norton Rixson 403000 is the heavy duty floor closer itself, an offset hung, Grade 1 unit rated for high traffic commercial openings with a rust-proof cement case. The 15323 attaches to a door bottom rail; it does not control the door on its own, so it cannot stand in for the closer. Buyers replacing a worn bottom arm on an existing floor closer opening want an arm; buyers replacing the mechanism in the floor want the 403000.
5) The opening needs the door to stay open on its own. What handles hold open if the Norton Rixson 403000 does not?
The 403000 has no hold open feature, so hold open has to come from the closer package chosen for the opening rather than from an add-on to it. Where a surface closer is acceptable, hold open is handled at the arm or track: the LCN 4040SEH-3038 is a hold open track for the 4000 Series, and the Deltana DCHA1050 is a hold open arm for the DC10 closer. Both are hold open hardware for surface mounted closers, not parts that retrofit into a floor closer cement case. Specify the hold open requirement before the floor is cut, because the decision changes which closer family the opening takes.
6) Can the closing speed be adjusted separately for each direction of swing on a Norton Rixson 40 Series floor closer?
Yes, there are independent closing speed valves for each direction of swing, so the two sides can be tuned separately rather than sharing one setting. A delay function is included as well, which is what you want on an opening where carts, gurneys or luggage need extra time through the door before the closer takes over.
7) Should I use a floor closer or a surface mounted overhead closer on my entrance?
A floor closer like the Norton Rixson 40 Series is the answer when nothing can show above the door: all glass entrances, narrow top rails, or a design where a surface closer body on the door or frame is unacceptable. The trade is install cost and permanence, because it needs an opening cut and routed in the floor for the cement case. A surface overhead closer with an arm or track mounts to an existing door and frame with no floor work at all, and it is the cheaper retrofit on a standard hollow metal or wood opening. If the slab cannot be cut, the decision is made for you.
8) Is a Deltana cushion arm or an LCN cush shoe support an alternative to a Norton Rixson floor closer?
No, and it is worth being clear about it because the search results mix them together. The Deltana DCCA4041 cushion arm for the DC40 and the LCN 1260-30 cush shoe support are arm and bracket parts for surface mounted overhead closers, and the LCN 1260-18QF is a mounting bracket kit of the same sort. The Norton Rixson 40 Series is the closer itself, set into the floor in a cement case. None of those accessories will fit it or replace it.
9) Do I need a floor plate or can the Norton Rixson 40 Series closer go under a threshold?
Both are offered. The 40 Series can be supplied for floor plate installation or for threshold installation, so the choice comes down to what is at the opening: an existing or planned threshold at an exterior entrance can conceal the closer, while an interior opening with finished floor running through usually takes the floor plate. Decide this before the slab is cut, since the two prep differently.
10) Is the LCN 1260-30 cush shoe support or the 1260-18QF bracket kit needed with a Norton Rixson 403000?
Neither. The LCN 1260-30 is a cush shoe support sized for a 3-1/16 inch reveal and the LCN 1260-18QF is a quick fix bracket kit, both mounting hardware for surface applied closers in the LCN 1260 and 1000 Series that solve reveal and frame mounting problems above the door. The 403000 is a floor closer set in a cement case below the door, and it ships with a 340 top pivot plus wood and machine screws for its own installation. Reveal dimensions and header brackets are not part of that install.
11) Can a Cal-Royal 900 Series accessories kit or a Deltana DCCA4041 cushion arm be ordered against a Norton Rixson 40 Series floor closer?
No, these are series specific parts for other closer families. The Cal-Royal 900 Series accessories kit is built for Cal-Royal 900 Series door controls, and the Deltana DCCA4041 is a cushion arm for the Deltana DC40 closer. Despite the number, DC40 is a Deltana series and not the Norton Rixson 40 Series, which is where the 403000 sits. Closer accessories are keyed to the manufacturer series they were made for, so match the part to the closer already on the opening before ordering.
12) The door is on a fire rated opening. Does the Norton Rixson 403000 or an LCN 4040SE-3038 track cover that?
They address different parts of the opening. The LCN 4040SE-3038 is a standard track for fire and life safety door closers in the 4040SE Series, a surface mounted track application. The 403000 is a Grade 1 heavy duty commercial floor closer for offset hung doors in high traffic locations, with independent closing speed valves for each direction of swing and a delay function. Confirm the fire rating requirement for the opening against the closer assembly being specified, since the two mount in entirely different places and are detailed separately on the drawing.
13) Is the Norton Rixson 40 Series floor closer the right choice for a school or hospital corridor door?
It suits those buildings. Grade 1 construction with a high traffic rating covers the cycle counts you see in educational and healthcare corridors, and the delay function gives beds, carts and wheelchairs time through the opening before the door starts closing. For standardizing across a facility, the 40 Series is a single non hold open floor closer platform, so every opening you put it on behaves the same way once the speed valves are set.
