Norton Rixson H40N90-626 – Frequently Asked Questions

1) Will the Norton Rixson H40 floor closer handle a 1000 lb entrance door?
That's exactly what the H40 is built for. The H40 Series center hung floor closer is rated for doors weighing up to 1000 lbs, with door sizes up to 4'0" x 8'6" (1219 x 2591mm) and a 2 inch minimum door thickness. If your door is thinner than 2 inches, this is the wrong closer, regardless of weight. It carries ANSI/BHMA A156.4 Grade 1 and a high traffic rating, so it's intended for entrance openings that cycle all day.
2) Is the H40 floor closer center hung or offset pivot?
Center hung. The H40 mounts on the door's centerline and swings both directions, so it needs a center hung door prep at both the floor and the head, not an offset pivot prep. Swapping a closer from offset pivot to center hung means re-prepping the door and frame, so confirm what's cut into your existing door before ordering.
3) Does the Norton Rixson H40 come with the top pivot, or do I order that separately?
The H340 top pivot ships with the H40, along with the steel cement case for the floor. You still need to supply the auxiliary door stop, overhead or floor type, because the closer itself doesn't stop the door at the end of its swing.
4) Can I get the H40 to hold the door open?
Only by ordering the hold open arm version. The H40 is offered with either an automatic hold open arm or a non-hold open arm, and that's a build choice, not a field adjustment. The base closer without that arm returns the door to center every time. On a fire rated opening, hold open hardware generally isn't permitted unless it releases on alarm, so check what your opening is rated for before specifying the hold open arm.
5) Is there an ADA compliant version of the H40 floor closer?
There's a lighter spring option built for lower opening force, which is the usual route to meeting an accessible opening force requirement on an interior door. Order it by selecting the lighter spring on the closer. Be realistic about the trade: a lighter spring on a heavy exterior door in a windy opening may not reliably close and latch, so the lighter spring makes most sense on interior openings.
6) How far does an H40 floor closer let the door swing open?
The H40 is ordered for either 90 or 100 degrees of controlled swing, and the mechanism allows door opening up to 103 degrees. Pick the swing degree against what's beside the opening: if a wall return, a column, or a side light sits inside the arc, order the 90. Either way an auxiliary stop is required, since the closer isn't the stop.
7) Can I adjust the closing speed separately in each direction on a double acting floor closer?
Yes, and it matters on a double acting door. The H40 has separate closing speed valves for each direction of swing, so a door that closes correctly pulling in but slams going out can be tuned without compromising the other direction. It also has a delay function for openings where people need extra time to clear the door.
8) Should I use a floor closer or a surface mounted overhead closer on a heavy entrance door?
It comes down to door weight, swing direction, and what the door looks like. A floor closer like the H40 carries the door's weight on a thrust bearing in the floor, handles double acting swing, and hides the hardware, which is why it's the choice on all glass and heavy monumental entrances up to 1000 lbs. A surface overhead closer is far simpler to install and service because it doesn't need the floor cut and a cement case set, but it only controls a single direction of swing and it's visible on the door or frame. If your door is single acting, hung on butt hinges, and within an overhead closer's weight range, the surface unit is the easier job. If the floor is already poured and uncut, that also argues against a floor closer.
9) Can I replace my LCN or Dorma surface closer arm with an H40?
No, and it isn't a close call. The H40 is a floor closer set into a cement case under the door with a center hung pivot at the head. Surface closer parts, like the Dorma 15323 1-1/2" offset bottom arm with cover, the LCN 4040SE-3038 standard track, or the LCN 1260-30 cush shoe support, all belong to closer bodies mounted on the door or frame. If you're servicing an existing surface closer, stay in that family and match the arm or track to your closer body. The H40 is a new opening or a full re-prep.
10) Can the LCN 4040SEH-3038 hold open track be used to add hold open to a Norton Rixson H40 floor closer?
No. The LCN 4040SEH-3038 is a hold open track built for the 4000 Series surface closers, so it attaches to a closer body mounted on the door or frame and has no interface to a center hung floor closer mechanism. Hold open on the Norton Rixson H40 is set by the arm function itself, which is ordered as either Automatic Hold Open or Non-Hold Open, so the choice is made at the time the H40 is specified rather than added later with a track.
11) An existing door needs hold open at the entrance - is the Deltana DCHA1050 an alternative to ordering a Norton Rixson H40?
They solve the requirement at different points in the opening. The Deltana DCHA1050 is a hold open arm for the DC10 door closer, so it changes the arm on a closer that is already installed and keeps the existing closer body. The Norton Rixson H40 is a center hung, double acting floor closer rated for doors to 1000 lbs with the closer body set into the floor, and its hold open version is selected as the Automatic Hold Open arm function when the closer is ordered. If the door is hung on a floor closer and swings both directions, the DC10 arm does not apply to it.
12) Is the Dorma 15323 offset bottom arm the bottom hardware for a Norton Rixson H40?
No. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, which is the bottom arm for an offset hung door where the pivot point sits in from the edge of the door, and it is a standard duty part with no fire rating. The Norton Rixson H40 is center hung, with the closer spindle on the door centerline, and it ships with the H340 top pivot for that configuration. Offset bottom arms and center hung closers prepare the door and floor differently, so the two are not interchangeable on the same opening.
13) What is the difference between the Deltana DCCA4041 cushion arm and a Norton Rixson H40 when the requirement is to control a heavy entrance door in both directions?
The Deltana DCCA4041 is a cushion arm for the DC40 door closer, so it works with a single acting surface closer and cushions the swing in the one direction that closer controls. The Norton Rixson H40 is a double acting floor closer with adjustable closing speed valves for each direction of swing, ANSI/BHMA A156.4 Grade 1, heavy duty, rated for high traffic and doors to 1000 lbs. For a door that must swing and close both ways under heavy use, the control has to come from a double acting unit rather than from a cushion arm on a single acting closer.
14) Will the H40 floor closer match the other door hardware finishes in my building?
Across a typical commercial standard, yes. The visible parts are offered in 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed bronze, 613E dark oxidized satin bronze, 618 bright nickel, 619 satin nickel, 622 black painted, 625 bright chrome, 626 satin chrome, plus BSP black suede powder and WSP white suede powder. Those 6xx numbers are BHMA finish codes, so if your existing levers and exit devices are specified 626 or 613, order the closer in the same code and it lines up.
15) Is the Norton Rixson H40 rated for exterior doors and high traffic openings?
Commercial duty, interior or exterior. The H40 is classified heavy duty with a high traffic rating and holds ANSI/BHMA A156.4 Grade 1, the top grade in that standard for door controls. A sealed closer option is available, which is what you want where the closer sits in an exterior threshold or anywhere the case may see water or washdown.
16) Do I install the H40 with a floor plate or in the threshold?
Both methods are available for the H40, and the call is made by the floor condition. A floor plate suits an interior opening where the closer sits in the finished floor slab. Threshold installation is the route at an exterior entrance where the closer body has to land in the sill assembly. Either way the steel cement case gets set before the finish floor goes down, so this gets decided at rough-in, not at hardware install.
17) Will a Cal-Royal 900 Series accessories kit or the LCN 1260-18QF bracket kit cover the mounting hardware for a floor closer like the H40?
Those kits serve surface mounted closers. The Cal-Royal 900 Series accessories kit supplies accessories for the 900 Series, and the LCN 1260-18QF is a quick fix bracket kit for the 1000 Series, both of which bracket a closer body to a door or frame face. The Norton Rixson H40 mounts into the floor and comes with the H340 top pivot and a steel cement case, with the choice of floor plate or threshold installation, so its mounting package is part of the closer rather than a separate surface bracket kit.
18) The frame has a deep reveal - does that mean using a cush shoe support like the LCN 1260-30 instead of a Norton Rixson H40?
Reveal is a frame dimension that matters for surface closers, and the LCN 1260-30 is a cush shoe support with 3-1/16 inch reveal compatibility for that kind of installation. A Norton Rixson H40 is not governed by reveal at all, because the closer body sits in the floor on the door centerline as a center hung, double acting unit, opening to 103 degrees and returning the door to center. What the H40 does require instead is 2 inch minimum door thickness, a door no larger than 4 feet by 8 feet 6 inches, and a separate overhead or floor stop, since it is supplied without an integral stop.
