Norton Rixson 20NRH-626 – Frequently Asked Questions

1) How heavy and how wide a door can the Rixson 20 floor closer handle?
Doors up to 3 feet 0 inches wide and 200 lbs. That covers most interior commercial openings in wood or hollow metal, but a full glass or heavy monumental entrance door will run past it. The closer is rated standard duty for moderate traffic, so a main building entrance cycling all day is not what it was built for. For heavy duty service, the Dormakaba BTS80 concealed floor closer is a heavy duty body.
2) Do I have to specify handing when ordering a Rixson 20 floor closer?
Yes, handing is not optional here. The 20 is a single acting handed closer and is built left hand or right hand, so the wrong hand cannot be corrected in the field. Stand outside the door on the side it swings away from: hinges on your left is left hand. Get this wrong and the closer goes back.
3) Can a door on a Rixson 20 floor closer open a full 180 degrees without hitting the wall?
The 20 Series swings to a full 180 degrees where the trim allows it, and built in hydraulic backcheck cushions the last stretch of the opening arc from 140 to 180 degrees so the door does not slam into the adjacent wall or the stop. Backcheck is standard, not an add on option. What limits the swing in practice is the door trim and any projecting hardware, not the closer.
4) Is there an ADA option for the Rixson 20 floor closer for a lower opening force?
A lighter spring option is orderable on the 20 Series for openings that need a reduced opening force, and it is chosen at time of order, not swapped later. On the ANSI side, certain models with the PH prefix meet ANSI A117.1. If the opening is on an accessibility schedule, specify the lighter spring when you place the order.
5) Will the Rixson 20 floor closer hold the door open?
No. Every configuration of the 20 Series is non hold open, offered as Non-Hold Open or Non-Hold Open Fire-Rated. The door closes every time. If you need the door to stand open at a set degree, this closer will not do it, and on a fire rated opening a hold open is generally not what you want anyway.
6) What else do I need to order to install a Rixson 20 floor closer?
The 180 top pivot ships with the closer. M19 intermediate pivots are recommended for the installation and are ordered separately. Mounting screws, both wood and machine, are provided. On a taller than standard installation or where the floor finish stacks up, extended spindles are available in 1/2 inch increments up to 2 inches longer than standard, and the spindle length is picked at order time as a required selection.
7) The Norton Rixson 20 is rated for moderate traffic. What floor closer should I use on a high-traffic entrance instead?
Step up to a heavy duty body. The Norton Rixson 20 is a standard duty closer rated for moderate traffic and doors up to 200 lbs, which suits interior openings that cycle at an ordinary office or tenant pace. The Dorma BTS80 concealed floor closer is a heavy duty unit, which is the class to specify for a main entrance or lobby door that cycles constantly. Note the BTS80 is sold as a body only, so the top pivot and spindle hardware are ordered alongside it, and it is not fire rated - if the opening is in a fire-rated assembly, the 20 is offered in a non-hold-open fire-rated arm function.
8) I need a floor closer for a fire-rated door opening. Can I use a Dorma BTS80?
The Dorma BTS80 is not fire rated, so it is not the unit for an opening in a fire-rated assembly. The Norton Rixson 20 is ordered with the arm function specified, and one of those functions is non-hold-open fire-rated; it is also a non-hold-open design throughout, with no hold-open feature, which is what a fire door requires so the leaf closes and latches on alarm. Specify the fire-rated non-hold-open version and the handing, left or right, to match the leaf.
9) Which floor closer should I specify if the opening has to meet ADA opening force?
The Norton Rixson 20 is ordered with a lighter spring option, yes or no, and certain models carry ANSI A117.1 with the PH prefix, which is the accessibility standard behind ADA opening force. Specify the lighter spring version for a barrier-free interior door. Neither the Dorma BTS75V nor the BTS80 is offered here with an accessibility spring selection - the BTS75V is designated Grade 1 in the NHO non-hold-open function and the BTS80 is a heavy duty body - so where the drawing calls out accessible opening force, the 20 with the lighter spring is the one to write in.
10) How do I know if I need an extended spindle on a floor closer?
Extended spindles make up the distance when the finished floor sits higher than the closer case, which happens when tile, terrazzo, or a topping slab goes in over the rough floor after the case is set. The 20 Series offers them in 1/2 inch increments up to 2 inches longer than standard, so measure from the top of the closer case to the finished floor before you order. If the case sits flush with the finished floor, take None.
11) Is the Rixson 20 floor closer available fire rated?
Fire rated arm function is one of the two configurations on the 20 Series, offered as Non-Hold Open Fire-Rated alongside the standard Non-Hold Open. Both are non hold open, so the fire rated version differs in its listing, not in how the door behaves day to day.
12) Should I use a floor closer or an overhead closer on an interior commercial door?
A floor closer like the 20 Series puts the whole mechanism in a cast iron cement case below the finished floor, so nothing shows at the head of the door. That is why it gets specified on glass and aluminum entrances and anywhere the architect wants a clean opening, and it is also what makes it a bigger job: the floor has to be cut and prepped. An overhead closer mounts to the door and frame with no floor work at all, so on a retrofit where the floor is already poured and finished, overhead is usually the practical call. Choose the floor closer when the prep is being done anyway, when the appearance matters, or when the door is pivot hung.
13) Can I adjust the closing speed on the Rixson 20 after it is installed?
Closing speed is adjustable through a single valve controlling the sweep from 70 degrees down to 0. One valve, not the separate sweep and latch pair you get on a higher end closer, so you are setting the whole closing arc together. The closer also carries a delay function and built in vertical adjustment for keeping the door aligned as the opening settles.
14) Is the Dorma BTS80 a drop-in replacement for a Norton Rixson 20 floor closer?
Treat it as a different installation, not a swap. The BTS80 is a concealed floor closer sold as a body only and rated heavy duty, while the Norton Rixson 20 is a 3/4 inch offset hung standard duty closer that comes in its own cast iron cement case and includes the 180 top pivot. Because the 20 is offset hung, the door prep and pivot geometry are tied to that 3/4 inch offset; pulling a 20 and setting a BTS80 in the same floor pocket means confirming the case, the spindle, and the pivot arrangement all over again. To keep the existing floor prep, replace a 20 with a 20 and match the handing.
15) Which finish do I order to match the other door hardware in my building?
The 20 Series exposed parts come in thirteen finishes: 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, BSP black suede powder, and WSP white suede powder. Match the BHMA number already on your pulls and pivots, since 626 satin chrome and 630 stainless read similar in a photograph but do not match side by side on the same opening.
16) Is a cast iron cement case floor closer suitable for a school or healthcare corridor door?
The 20 Series cast iron cement case is rated standard duty for moderate traffic, which suits interior office, education, healthcare, retail and multi-tenant residential doors. A high cycle main entrance or a hospital corridor that never stops moving is beyond moderate traffic, and for those the Dormakaba BTS80 is a heavy duty body. Judge it by cycles at the opening, not by the building type on the drawing.
17) Does the Norton Rixson 20 come in matching finishes, or do I need a different closer to match my existing door hardware?
The Norton Rixson 20 covers a wide finish range without going to another product: 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. That range lets a property manager standardize the visible cover across a floor of doors on the 20 itself. The Dorma BTS75V and BTS80 are both body-only units, so the visible cover plate on those is a separate specification.
