Norton Rixson 40N90-626 – Frequently Asked Questions

1) Will the Norton Rixson 40 Series floor closer handle a 300 lb glass or solid core door?
Yes, up to 300 lbs. The 40 Series is a heavy duty, center hung floor closer, and the door's weight rides on the closer mechanism itself rather than on hinges or a top pivot. Anything heavier than 300 lbs is outside what this closer is rated to carry.
2) Do I need to specify handing on a Norton Rixson 40 floor closer?
No handing to specify. The 40 Series is double acting, so the door swings both directions and the closer is non-handed. Each direction of swing gets its own adjustable closing speed valve, so in and out can be tuned separately.
3) Is the Norton Rixson 40 floor closer Grade 1 for a high traffic commercial entrance?
Certified ANSI/BHMA A156.4 Grade 1, rated high traffic, and specified as commercial. That's the grade a spec normally calls for on a main entrance or a heavily used interior opening in an office building, school, hospital, or municipal facility.
4) How far does the door open with a Rixson 40 Series floor closer, and do I still need a door stop?
Maximum opening is 103 degrees, and yes, you still need a stop. The installation calls for an auxiliary door stop, either overhead or floor type, and that is a separate item to order. The closer itself is not a stop.
5) Does the Norton Rixson 40 floor closer come with the top pivot, or do I order that separately?
The 340 top pivot is included, so the complete center hung set is covered. What is not included is the auxiliary door stop, and you'll also need to decide between floor plate and threshold installation for the case, plus templates and prep for both the door bottom and the floor.
6) Is a floor closer the right choice, or should I use a surface mounted door closer?
Go floor closer when the door is heavy, when it has to swing both ways, or when you don't want hardware showing at the head, which is the usual call on glass entrances and lobby doors. The 40 Series carries the door weight in the floor, up to 300 lbs, and takes the swing both directions. A surface closer is the simpler and far cheaper install for a standard single-acting hollow metal or wood door, and it retrofits without cutting the floor. Cutting a cement case into an existing slab is the cost that decides this, so on a replacement job the surface closer usually wins unless the door is center hung already.
7) Can an LCN 4040SE standard track or 4040SEH hold open track be used in place of a center hung floor closer?
No. The LCN 4040SE-3038 is a standard track for fire/life safety door closers and the LCN 4040SEH-3038 is a hold open track, both accessories that mount on the door and frame as part of a surface closer assembly. The Norton Rixson 40 Series is a center hung floor closer, meaning the closer body sits in the floor and carries the weight of the door up to 300 lbs. The two mount in entirely different places and prep differently, so a track cannot take the place of the floor closer.
8) When do I need the extended spindle option on a floor closer?
The spindle has to reach up through the floor covering and into the door's bottom pivot. If the closer sits below finished floor because of thick terrazzo, tile, or a mortar bed, order an extended spindle. The 40 Series offers them in 1/2 inch increments up to 2 inches: 1/2, 1, 1-1/2, and 2. If the closer body sits at finished floor level, take None.
9) Should I order the sealed version of the Rixson 40 floor closer?
Take the sealed closer for any opening where water gets to the floor: exterior entrances, garage and loading doors, wash-down areas, or a threshold-mounted install where runoff collects. The 40 Series is built for interior and exterior use either way, but the sealed case is what protects the cement case installation from moisture. Dry interior lobbies and vestibules don't need it.
10) Does the Rixson 40 Series meet ADA closing force requirements?
There's a lighter spring option built for exactly that. Order the 40 Series with the ADA lighter spring where the opening has to meet reduced opening-force requirements, such as accessible entrances and restrooms in schools, healthcare, and government buildings. The standard spring is the one to use where you want the stronger close on a heavy or exterior door.
11) Does the Rixson 40 floor closer hold the door open, and can I get a hold open version?
Both are offered. Arm function comes as non-hold-open or automatic hold open on the 40 Series, so pick automatic hold open where you want the leaf to stay put for deliveries or move-ins. Note that a hold open closer is not what you want on a door that has to self-close for smoke or fire separation.
12) Does the 40 Series floor closer have a delay function?
Yes, delayed action is included. That's the feature that holds the door open longer on the first part of the close, which is what you want on an accessible entrance, a hospital corridor, or anywhere carts and gurneys go through. Pair it with the ADA lighter spring on openings that need reduced opening force.
13) How do I keep a pair of double acting doors lining up in the center?
The 40 Series uses a centering arm with adjusting screws that land in the face of the door, so alignment is set after the doors are hung rather than being fixed by the prep. That's the adjustment that matters on double acting pairs, where both leaves have to return dead center against each other. Set the closing speed valves for each direction after the centering is right.
14) I just need a replacement arm or bracket for an existing door closer, not a whole floor closer. What are my options?
The 40 Series is a complete floor closer assembly, not a service part, so it isn't what you want for a repair. For arm and bracket level parts ZenSupply carries the Deltana DCHA1050 hold open arm for the DC10 closer, the Deltana DCCA4041 cushion arm for the DC40, the Dorma 15323 1-1/2 inch offset bottom arm with cover, the LCN 1260-18QF quick fix bracket kit, the LCN 1260-30 cush shoe support for a 3-1/16 inch reveal, and the Cal-Royal 900 Series closer accessories kit. For LCN 4040SE fire and life safety closers there are the 4040SE-3038 standard track and the 4040SEH-3038 hold open track.
15) I need hold open on a door with a floor closer. Is a Deltana DCHA1050 hold open arm the answer?
The Deltana DCHA1050 is a hold open arm for the Deltana DC10 door closer, so it only fits that closer. On a Norton Rixson 40 Series floor closer, hold open is selected on the closer itself through the arm function, which is offered as automatic hold open or non-hold open. Order the 40 Series with the automatic hold open arm function rather than adding a separate arm.
16) Will a Cal-Royal 900 Series accessory kit or LCN 1260 bracket parts adapt a surface closer to a floor installation?
No. The Cal-Royal 900 Series accessories kit serves Cal-Royal 900 Series door controls, the LCN 1260-18QF is a quick fix bracket kit and the LCN 1260-30 is a cush shoe support for 3-1/16 inch reveal, all of which address mounting a closer on the door and frame. None converts an opening to center hung. The Norton Rixson 40 Series is itself the floor closer, center hung mounting, and is installed by floor plate or threshold preparation.
17) What's the difference between the 90 and 100 degree swing option on a floor closer?
That value sets where the closer's own arm geometry works to, within the 103 degree maximum the 40 Series allows. Pick 90 where the door is against a return wall or in a vestibule and can only reach square. Pick 100 where the opening is clear and you want the leaf further out of the traffic path.
18) Is there a black or white finish floor closer for a storefront entrance?
Four dark or painted options on the 40 Series: 622 black painted, BSP black suede powder, WSP white suede powder, and 613 oil rubbed bronze. BSP and WSP are the ones that match powder coated aluminum storefront framing. For polished storefront the usual matches are 625 bright chrome and 626 satin chrome.
19) For an ADA compliant closing force on a high traffic entrance, do I need a different closer than the 40 Series?
Not necessarily. The Norton Rixson 40 Series can be ordered with a lighter spring for ADA, and it is a Grade 1 closer under ANSI/BHMA A156.4 with a high traffic rating, so the lighter spring option does not require stepping down to a lighter duty product. By contrast, an accessory such as the Deltana DCCA4041 cushion arm belongs to the Deltana DC40 closer and does not change spring force on a floor closer.
