Norton Rixson 2790N-RH-626 – Frequently Asked Questions

1) Can a Norton Rixson 27 floor closer be used on a double acting door that swings both ways?
No. The 27 Series is a single acting closer, so it controls a door that swings one direction only. Everything about the way it is built follows from that: it is handed left or right, it is hung 3/4 inch offset rather than center hung, and the built in dead stop sets where the door stops on the open side. If your opening has to swing in and out, a single acting floor closer is the wrong part for it.
2) My doors are hung on 3/4 inch offset pivots. Is the Rixson 27 Series the right floor closer for that prep?
That is exactly what the 27 is built around. Hang type is offset hung and the mounting method is offset, at 3/4 inch. A 1-1/2 inch offset version of the same closer is made if the frame is prepped deeper, and the closer has vertical door adjustment so the leaf can be brought back into alignment after it is set. On a center hung door none of this applies and you need a center hung closer instead.
3) Do I have to specify a hand when I order a Rixson 27 floor closer?
Yes, left hand or right hand is a required choice on the 27, because it is a single acting closer built for one swing direction. Get it from the door you are replacing or from the swing on the drawing before you order. You pick the dead stop degree at the same time, so have both the hand and the stop angle in front of you when you place the order.
4) What else do I need to order with a Rixson 27 floor closer to finish the job?
Pivots are the main thing. The installation uses a 180 top pivot plus the M19 intermediate pivots, and the M19 pivots are ordered separately from the closer. The closer body itself comes in its Cycolac rust proof cement case, which is what gets set in the floor. Two other decisions belong on the order: floor plate or threshold installation, and spindle length, which can be taken up to 2 inches longer than standard if the finished floor build up calls for it.
5) Can the Rixson 27 stop the door before it hits the wall behind it?
It has a built in positive dead stop, and you choose the angle when ordering: 85, 90, 95, or 105 degrees. Measure from the open face of the door to whatever is behind it, then pick the setting that lands short of it. The stop is part of the closer, so on most of these openings you are not adding a separate wall or floor stop to catch the door.
6) Will this floor closer control an exterior entrance door that catches wind?
Backcheck is one of three independent valves on the 27, alongside closing speed and latch speed, so you can slow the door down before it flies past its stop when a gust takes it. The closer is rated for exterior as well as interior openings up to 4' 0" wide, and the cement case is Cycolac and rust proof, which is what matters when the body lives in a floor pocket at an entrance.
7) If a job specifies a Grade 1 floor closer, what alternative meets that besides the Norton Rixson 27?
The Dormakaba BTS75V also carries a Grade 1 rating, so it holds the same grade line on a spec sheet as the Norton Rixson 27 Series, which is certified to ANSI/BHMA A156.4 Grade 1. Where they part company is function: the BTS75V is a non hold open closer, and the Norton Rixson 27 is ordered in either non hold open or selective hold open. Match the function to the drawing, not just the grade.
8) The door needs to stand open on demand. Does the Dormakaba BTS75V do that, or is the Norton Rixson 27 the right call?
The Dormakaba BTS75V is a non hold open closer, so the door returns every time. The Norton Rixson 27 Series is built in a selective hold open arm function as well as non hold open, which is the one to order for a vestibule or loading entrance that has to stay parked open during deliveries. Specify the hold open version at order time, since arm function is not a field adjustment.
9) Is the Dormakaba BTS75V a straight drop-in for a Norton Rixson 27 floor closer?
Not on its own. The Dormakaba BTS75V is a floor closer body with cement case supplied less spindle, so the spindle is a separate item to source before the door can be hung. The Norton Rixson 27 Series is an offset hung closer with a hardened one-piece steel spindle and extended spindle options up to 2 inches longer than standard, so on a Norton Rixson replacement you are matching spindle length to the finished floor rather than adding a spindle line to the order.
10) The existing floor closer is concealed under a center pivot. Can I put a Norton Rixson 27 in that opening?
The Norton Rixson 27 Series is an offset hung closer with a 3/4 inch offset and a 1-1/2 inch offset option, so it expects the door to be hung off the pivot centerline. For a concealed arrangement the Dormakaba BTS80 concealed floor closer body is the closer that matches that layout. Check the existing case and pivot prep in the floor first, since swapping between offset and concealed geometry means new floor work, not just a new closer.
11) Can a Norton Rixson 27 floor closer hold the door open?
Two arm functions are offered on the 27: Non-Hold Open and Selective Hold Open. Order Selective Hold Open if the door needs to stand open, for deliveries or during business hours; order Non-Hold Open if it should close from every position, which is what you want on an opening that has to stay latched. This is chosen at order time, so decide it per door rather than per building.
12) Can the closing be slowed down for wheelchair traffic or carts going through the door?
Delayed action is part of the 27, and closing speed and latch speed sit on their own valves, so you can hold the door slow through the first part of the close and still let it pick up speed to latch. On healthcare and school openings that is usually paired with the lighter spring option, which is a separate choice on the order.
13) Is there a lighter spring version of the Rixson 27 for an accessible opening?
Yes. Lighter Spring is a yes or no choice when you order the 27, and the accessibility models carry the PH prefix. If the opening has to meet a reduced opening force for your facility, order the lighter spring build rather than trying to back the standard spring down after it is set in the floor.
14) Is the Norton Rixson 27 Grade 1, and will it hold up on a school or hospital entrance that gets used all day?
Certified to ANSI/BHMA A156.4 Grade 1, heavy duty, and rated for high traffic commercial use. Grade 1 is the top grade in A156.4, which is the standard institutional and government specs call out. The closer runs a one piece hardened steel spindle and a Cycolac rust proof cement case, so it is the specification you would standardize on across a campus rather than a light commercial closer.
15) Is there a UL Listed version of the 27 Series floor closer for a labeled opening?
UL Listed models of the 27 are the F prefix versions, so call out the F prefix when the opening carries a label. The base closer is certified to ANSI/BHMA A156.4 Grade 1. Model designation on the standard build is 27N.
16) What else could I look at instead of the Rixson 27 if I need a heavy duty floor closer?
ZenSupply also carries the Dormakaba floor closers. The Dorma BTS75V is Grade 1 like the 27 and ships with its cement case but less spindle, and it is listed as non hold open only, so if you want a door that stands open the 27's Selective Hold Open arm is the real difference between them. The Dorma BTS80 is heavy duty and is recorded as not fire rated. Both Dorma items are sold as closer bodies, where the 27 is ordered as a closer in its Cycolac cement case with the hand, stop degree, arm function and finish specified.
17) Is a Dorma BTS75V a drop in replacement for an existing Rixson 27 floor closer?
Not a like for like swap. Both are Grade 1 floor closers, but the 27 is a 3/4 inch offset hung single acting closer sold with its Cycolac cement case, while the BTS75V is a closer body with cement case and less spindle, non hold open only. Floor closers are matched to the cement case, spindle and pivot prep already sunk in the floor, so crossing brands normally means breaking out the old case and setting a new one. If the existing unit is a 27, replacing it in the 27 Series keeps the offset, the spindle and the top and intermediate pivot arrangement the same.
18) The Dormakaba BTS80 is listed as a body only. What does that change against a Norton Rixson 27 order?
The Dormakaba BTS80 is a concealed floor closer body only, so the closer body is what ships and the surrounding pivot and case components are handled separately. The Norton Rixson 27 Series is likewise built out with a 180 top pivot and M19 intermediate pivots ordered separately, so on either brand the takeaway is the same for a contractor pricing the opening: budget the pivots as their own lines and confirm the case arrangement before the floor is poured.
19) Which floor closer suits a fire rated opening, the Norton Rixson 27 or the Dormakaba BTS80?
The Dormakaba BTS80 carries no fire rating. The Norton Rixson 27 Series is available in UL Listed models under the F prefix, so for a rated stair or corridor door the F prefix Norton Rixson is the one to specify. Have the door and frame labels in hand when you order, because the closer alone does not carry the opening.
20) Can I get the 27 floor closer in a finish that matches the rest of the door hardware in my building?
Thirteen finishes are offered on the 27: 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. On commercial openings 626 satin chrome and 630 stainless finishes are the usual house standard, so 626 is the safe match if the rest of the building is unmarked.
21) Both closers mention a cement case. Does that mean the same floor prep for the Norton Rixson 27 and the Dormakaba BTS75V?
Both are cement case floor closers, so both are set into the slab rather than surface mounted, and both need the case located before the floor is finished. The Norton Rixson 27 Series uses a Cycolac rust-proof cement case, which is the detail to raise on a wash down area or an exterior entrance where the case sits in a wet slab. The Dormakaba BTS75V is supplied with its cement case as part of the body.
