Norton Rixson H2890N-RH-626 – Frequently Asked Questions

1) Will the Norton Rixson H28 floor closer handle a 1000 lb exterior door?
That's exactly what the H28 is built for. It's rated to 1000 lbs with doors up to 4'0" x 8'6" (1219 x 2591mm), interior or exterior, on a cast iron cement case with a hardened one-piece steel spindle. Maximum door width is 48 inches, so a leaf wider than that is outside the rating no matter what it weighs. The closer carries the door's full weight through the floor, which is why this style gets specified for tall, heavy entrance doors where an overhead unit would be working against the leaf.
2) My door is 1-3/4 inch thick. Can I still use the H28 floor closer?
Only with the 587 side load arm. The H28 is designed around a 2 inch minimum door thickness, and 1-3/4 inch doors need the special 587 arm, which requires a 2-3/4 inch minimum backset at the pivot point. That arm is an ordering option on the closer, so specify it when you place the order rather than trying to add it later. If your opening can't give up 2-3/4 inches of backset, the H28 isn't the right closer for that leaf.
3) Does the H28 floor closer need to be ordered left hand or right hand?
Handing is required. The H28 is a single-acting closer, meaning the door swings one way only, so it's built left hand or right hand and the two are not interchangeable. Stand outside the door on the side it swings away from: hinges (or in this case the pivot) on the left is left hand. Get it wrong and the closer won't work with your swing direction.
4) Will the H28 floor closer meet ADA door opening force for a barrier-free entrance?
There's a lighter spring option built for that. The H28 can be ordered with the lighter spring for accessibility, and certain models (the PH prefix) meet ANSI A117.1 accessibility requirements. If the opening is on an accessible route, specify the lighter spring at order time. Be aware of the trade-off on an exterior door: less spring power means less authority against wind load on a heavy leaf.
5) Can I set a floor closer to stop the door before it hits the wall?
The H28 has a built-in positive dead stop, and you pick the angle when you order: 85, 90, 95 or 105 degrees. It's a mechanical stop inside the closer, not an accessory, so the door physically cannot swing past that point and you don't need a separate floor or wall stop. On a heavy leaf that matters, a 1000 lb door swinging into a wall does real damage. Measure the clear swing before you choose the degree, because it's specified per unit and not field-adjustable to any angle you like.
6) Is the LCN 4040SE-3038 track a substitute for a Norton Rixson H28 floor closer?
No. The LCN 4040SE-3038 is a standard track for fire/life safety door closers in the 4040SE Series, so it belongs to a surface-applied closer mounted on the door or frame face. The Norton Rixson H28 is a single acting closer set into the floor in a cast iron cement case, carrying door weight up to 1000 lbs through the closer itself. The two are not interchangeable, and a door prepped for a floor pocket and an H340 top pivot cannot be closed by a track. If the opening is a surface closer application rather than a floor-closed one, the 4040SE-3038 track is the right family; if the door hangs on a floor closer, stay with the H28.
7) I need a hold open on a floor closed door - can I add a Deltana DCHA1050 hold open arm?
No. The Deltana DCHA1050 is a hold open arm built for the DC10 door closer, which is a surface closer arm assembly and has no connection to a floor closer spindle. The way to get hold open behavior on the Norton Rixson H28 is to order it with the Selective Hold Open arm function instead of Non-Hold Open, which is chosen at the time of order rather than added later. A property manager standardizing entry doors should decide hold open at order, because the H28 as configured without it does not accept a bolt on hold open arm.
8) Does the H28 floor closer hold the door open?
Only if you order the selective hold open arm. The base H28 arm function is non-hold-open, and the closer's own hold open feature is listed as none. Selective hold open is an arm option, chosen at order time, that lets the door stand open at the set degree when you push it there and release normally otherwise. If you need a door that parks open on a loading corridor or a receiving door, specify that arm; otherwise the door closes every cycle.
9) Is the Norton Rixson H28 Grade 1 for a high traffic entrance?
ANSI/BHMA A156.4, Grade 1, and it's rated high traffic, commercial duty. Grade 1 is the top tier of that standard for door controls, which is what most institutional and government specs call out. For an MRO or facility buyer standardizing an entrance package, that's the line item that satisfies the spec.
10) Should I use a floor closer or an overhead closer on a heavy glass-front entrance door?
Weight and appearance decide it. A floor closer like the H28 sits in a cement case below the finished floor and carries the door's full weight through the closer, which is why it goes on doors up to 1000 lbs where an overhead unit would be fighting the leaf. Nothing shows above the door, and being concealed in the floor it's vandal resistant, so it's the usual answer on storefront and monumental entrances. An overhead closer, mounted on the door or frame, is faster and cheaper to install and doesn't require cutting the slab, but it's visible and it's not carrying door weight. If the floor is already poured and you can't pocket it, an overhead is the practical route.
11) Does the Norton Rixson H28 come with the top pivot, or do I order that separately?
The H340 top pivot ships with the closer, along with wood and machine screws, and you choose floor plate or threshold installation. There's a less-top-pivot option if you already have the H340 from a previous order or the frame is prepped with one, so don't pay for a second pivot you won't use. Everything else, the floor pocket forming and the slab work, is on your side.
12) Can I adjust the closing speed and latching on a Norton Rixson H28 after it's installed?
Three independent valves: closing speed, latch speed, and backcheck, each adjusted separately. Backcheck is the one that saves the door in a windy exterior opening, it slows the leaf before it reaches the open position. There's also a delay function on the H28, useful where someone needs extra time to get through. Set them after the closer is in and the door is hung, then cycle the door through full travel to confirm it latches.
13) Can I use the H28 floor closer on a pair of doors?
Yes, but as two closers. The H28 is single acting and handed, so a pair takes one left hand unit and one right hand unit, each in its own floor pocket, each with its own dead stop degree and finish. Order them as a matched pair and keep the spring setting the same on both, otherwise the two leaves close at noticeably different rates.
14) Can I swap an H28 floor closer for a door closer arm or bracket kit?
No, and it's worth being clear about the difference. The H28 is a complete closer body set into the floor. Parts like the Deltana DCHA1050 hold open arm for the DC10, the Deltana DCCA4041 cushion arm for the DC40, the Dorma 15323 1-1/2 inch offset bottom arm, the LCN 1260-18QF quick fix bracket kit, or the LCN 4040SE-3038 and 4040SEH-3038 tracks are components that mount to an existing overhead closer of their own series. They don't substitute for a floor closer and they won't carry door weight. If your opening already has an overhead unit and you only need to change the arm or the track behavior, one of those is what you want, not an H28.
15) The Dorma 15323 offset bottom arm mentions offset - does that make it a match for an offset hung H28?
No, the shared word covers two different things. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover rated Standard Duty and not fire rated, so it is an arm component sized to a reveal on a surface or overhead application. The Norton Rixson H28 is offset hung as an in floor closer, meaning the door pivots on the closer spindle set below the finished floor, and it is a Heavy Duty unit under ANSI/BHMA A156.4 Grade 1 carrying doors up to 48 inches wide. A contractor reading offset on a drawing should confirm which of the two conditions the detail describes before ordering.
16) My reveal is too deep for the closer arm - is the LCN 1260-30 cush shoe support an alternative to a floor closer?
They solve different problems. The LCN 1260-30 is a cush shoe support for door closers with 3-1/16 inch reveal compatibility, and the LCN 1260-18QF is a quick fix bracket kit in the 1000 Series, both of which address how a surface closer arm lands on a frame with an awkward reveal. The Norton Rixson H28 removes the reveal question entirely because nothing mounts on the frame face; the closer sits concealed in the floor and the only overhead component is the H340 top pivot. Where the frame condition is the obstacle and the door is within 48 inches wide and 1000 lbs, the H28 is the alternative approach rather than a bracket fix.
17) For an ADA barrier free opening, does an LCN 4040SEH-3038 hold open track do the same job as an H28 with the lighter spring?
They meet the requirement in different ways on different doors. The LCN 4040SEH-3038 is a hold open track in the 4000 Series, an overhead track component that holds the door open at a set point. The Norton Rixson H28 addresses barrier free operation through a Lighter Spring (ADA) option ordered with the closer, with PH prefix models meeting ANSI A117.1 accessibility requirements, and it also has separate closing speed, latch speed and backcheck valves for fine adjustment plus a positive dead stop at 85, 90, 95 or 105 degrees. An institutional buyer specifying for a monumental or high traffic entrance carrying door weight through the floor should look at the H28 configuration rather than an overhead track.
18) What finishes does the Norton Rixson H28 floor closer come in?
Thirteen, and they're what you match the threshold plate and pivot to since that's the visible part: 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. For a property manager matching existing openings, 626 satin chrome and 613 oil rubbed bronze are the two that most commonly line up with door hardware already in a building.
19) What is the sealed closer option on the H28 and when do I need it?
Sealed is a yes/no choice on the H28 order. It's the option to take when the floor pocket may see water or washdown, an exterior entrance, a garage or loading area, a wet-cleaned lobby, anywhere the case could take standing moisture. On a dry interior slab it's not needed. Decide it at order time; it's a construction difference in the closer body, not something added afterward.
20) Will a Cal-Royal 900 Series accessories kit cover the parts I need for an H28 installation?
No. The Cal-Royal 900-ACC is a door closer accessories kit for the Cal-Royal 900 Series, so its contents are matched to that manufacturer's surface closers. The Norton Rixson H28 ships with its own H340 top pivot along with wood and machine screws, and its configurable pieces are ordered on the closer itself: sealed closer, extended spindle in 1/2, 1, 1-1/2 or 2 inch, the 587 side load arm for 1-3/4 inch thick doors with a 2-3/4 inch minimum backset, and a less top pivot option when a pivot is already in hand. A distributor building the order should set those options on the H28 rather than sourcing a separate accessory kit.
21) What is the difference between a Deltana DCCA4041 cushion arm and the backcheck on a Norton Rixson H28?
The Deltana DCCA4041 is a cushion arm for the DC40 door closer, an arm assembly that cushions the swing on that surface closer. The Norton Rixson H28 handles the same concern internally, with separate and independent valves for closing speed, latch speed and backcheck, and a positive dead stop that can be set at 85, 90, 95 or 105 degrees so the door does not travel past the chosen point. On a wall or adjacent glass that must be protected, the H28 dead stop is set at the closer rather than by an arm on the frame.
