Norton Rixson 40N-LAP – Frequently Asked Questions

1) What door weight and width can a Norton Rixson 40 Series floor closer handle?
The 40 Series center hung floor closer is rated for doors up to 450 lb (204 kg) and up to 4 ft 0 in (1219 mm) wide. That covers most heavy entrance doors in commercial lobbies and institutional entries. If your leaf is wider than 4 feet or heavier than 450 lb, this is the wrong closer and you need a larger capacity unit.
2) Is the Rixson 40 Series single acting or double acting?
The spec lists the door swing as single acting, so it is set up for a door that swings one direction and returns to a stop. Plan your frame stop and pivot layout accordingly before the floor is cut.
3) Is this floor closer certified for a Grade 1 commercial opening?
It is certified to ANSI/BHMA A156.4, Grade 1, and is classified as commercial heavy duty. A156.4 is the door controls standard, and Grade 1 is the highest cycle and performance tier in it, which is typically what a school, hospital, or government spec calls for on an entrance.
4) Will a center hung floor closer work on an aluminum storefront or glass door?
The 40 Series works with wood, metal, or glass doors, interior or exterior, because it mounts in the floor under the door centerline rather than on the door face or in the head. For a glass front installer that is the point of it: nothing shows above the threshold and the full glass leaf stays clean. Confirm the door is prepped for center hung pivots, not offset.
5) What is the closest equivalent to the Norton Rixson 40 Series floor closer from another manufacturer?
The Dormakaba Dorma BTS75V is the nearest match. Like the Norton Rixson 40 Series, it is a Grade 1 floor closer supplied in a non hold open function, and it ships as a closer body with cement case. The Norton Rixson 40 Series is certified to ANSI/BHMA A156.4 Grade 1, uses a cast iron cement case, and is a non hold open, single acting center hung unit rated for doors up to 450 lb and 4'0 wide. One ordering difference matters: the BTS75V is supplied less spindle, so the spindle must be specified separately to suit the door and pivot arrangement.
6) I need a heavy duty concealed floor closer but I already have a cement case in the floor. What should I order instead of the 40 Series?
Look at the Dormakaba Dorma BTS80, which is offered as a closer body only in a heavy duty rating. That suits a retrofit where the existing case stays in the floor and only the operating body is being replaced. The Norton Rixson 40 Series is also a heavy duty floor closer, but it is supplied with a cast iron cement case, which is what you want when the floor is being cut fresh rather than reused.
7) Do I need to order a left hand and right hand version of this floor closer?
No. The 40 Series is non handed and field reversible, so one unit covers either hand. That is useful for a property manager stocking spares across a building instead of carrying two part numbers.
8) Does the Rixson 40 Series come with a cement case?
Yes, the cover type is a cast iron cement case, which is what gets set in the floor pour or the cut opening before the closer body drops in. The closer body itself is cast iron with stainless steel internal components.
9) What adjustments can I make after the Rixson 40 Series is installed?
Three: closing speed, latch speed, and backcheck. Backcheck is what stops a wind gust or a hard push from throwing the door into the wall, which matters on exterior entrances. All three are set through the closer body once the unit is in the floor and the door is hung.
10) Can I retrofit a Rixson 40 Series into an existing floor closer pocket?
Treat it as a new prep rather than a drop in. Installation calls for cutting the floor opening and building a proper foundation for the cast iron cement case, using the manufacturer templates to lay out the holes under the door centerline. An old pocket from a different make rarely matches the case footprint, so verify against the template before you commit to the existing hole.
11) Can the Dorma BTS80 be used on a fire rated opening in place of the Norton Rixson 40 Series?
No. The Dormakaba BTS80 carries a fire rating of No, so it should not be specified where the opening requires a fire rated closer. The Norton Rixson 40 Series is an ANSI/BHMA A156.4 Grade 1 heavy duty commercial floor closer; on any labeled opening, confirm the listing requirements with the door and frame label before selecting either unit.
12) Is the Dorma BTS75V a hold open closer, and how does that compare to the Norton Rixson 40 Series?
Neither is a hold open unit. The Dormakaba BTS75V is listed with an NHO non hold open function, and the Norton Rixson 40 Series has no hold open feature, closing the door under spring control every cycle. If the specification calls for a floor closer that parks the door open at a set degree, neither of these two is the right selection.
13) For a double acting entrance, does the Norton Rixson 40 Series work or should I look at a Dorma floor closer?
Check the swing before ordering. The Norton Rixson 40 Series is catalogued with a single acting door swing, so a true double acting opening that swings both directions needs a closer specified for that duty. Among heavy duty floor closers, the Dormakaba BTS80 body and the Grade 1 BTS75V are the concealed alternatives to price against it, with the swing function confirmed against the opening before release.
14) What finishes does the Rixson 40 Series come in?
Finish options include 626 satin chrome, 630 satin stainless, and 613 oil rubbed bronze, along with other architectural finishes. On a floor closer only the cover plate shows, so pick to match the threshold and adjacent door hardware rather than the frame.
