  3. Prepare floor and door by drilling required holes and routing as specified for mortise arm with thru-bolt attachment installation.
  4. Install the floor closer unit with included 180° top pivot and M19 intermediate pivot, ensuring proper alignment for doors 60" to 90" in height.
  5. Adjust the three independent valves for closing speed, latch speed, and backcheck to achieve desired door operation and configure dead stop at specified degree (85°, 90°, or 95°).
  6. Test door operation throughout full range of motion and verify positive dead stop function prevents over-swing. Refer to manufacturer documentation for complete installation details and valve adjustment procedures.

Norton Rixson Q2785N-RH-626 – Frequently Asked Questions

1) Is the Norton Rixson Q27 floor closer for an offset-hung door or a center-hung door?
The Q27 is an offset-hung closer, built around a 3/4 inch offset. The spindle sits 3/4 inch off the pivot centerline, so the door hangs on a 180 degree top pivot and an intermediate pivot rather than swinging on a center axis. If your opening is prepped center hung, this is the wrong geometry and you need a center-hung floor closer instead.
2) Will a Rixson Q27 floor closer work on a double-acting door?
No. The Q27 is single acting, so it swings one way only. For a door that needs to swing both directions you need a double-acting floor closer, not this one.
3) What door thickness and size does the Q27 floor closer suit?
It's set up for 1-3/4 inch doors, the standard commercial thickness, with door heights of 60 to 90 inches and widths up to 4 feet 0 inches. Taller than 90 inches, plan on an additional intermediate pivot for every 30 inches of extra height.
4) Do I have to specify handing when ordering a Q27 floor closer?
Yes, handing is a required choice. The Q27 is built left hand or right hand, so determine the door's hand at the opening before you order. A single-acting offset closer cannot be flipped in the field.
5) Can the Q27 floor closer hold the door open?
That depends on the arm you order. The Q27 comes with either a non-hold-open arm or a selective hold open arm. Choose selective hold open if you want the door to stay parked at the stop position; the base closer function itself is listed as non hold open.
6) What stop angles can I get on the Rixson Q27, and is the stop in the closer?
The dead stop is built into the closer, so you don't need a separate overhead or floor stop to limit the swing. Pick 85, 90, or 95 degrees when you order. If there's a wall, casework, or an adjacent door in the swing path, measure it before you settle on the angle, because it's fixed by the unit you buy.
7) Does the Q27 floor closer meet Grade 1 for a commercial entrance?
It's certified to ANSI/BHMA A156.4, Grade 1, and rated heavy duty for commercial use. That's the top grade for door controls under A156.4, which is what most institutional and municipal specs call for on a main entrance.
8) Does the Q27 floor closer come with the pivots, or do I order those separately?
The pivots come with it: a 180 degree top pivot and one M19 intermediate pivot, which covers doors 60 to 90 inches tall. Above 90 inches, add one more intermediate pivot for every 30 inches of additional height. Budget those extras separately on tall glass or monumental doors.
9) We need a hold open floor closer - does the Dorma BTS75V do that, or should we stay with the Norton Rixson Q27?
The Dorma BTS75V is a non hold open unit, so it will not answer a hold open requirement. The Norton Rixson Q27 is ordered by arm function in either non-hold-open or selective hold open, so the hold open requirement is met by choosing the selective hold open arm at the time of order rather than by changing product lines.
10) Does the Dorma BTS80 work on a fire rated opening in place of the Norton Rixson Q27?
The Dorma BTS80 floor closer is listed as not fire rated, so it is not the part to specify where the opening carries a fire label. The Norton Rixson Q27 is a Grade 1 commercial closer with UL listing available on F prefix models, so the F prefix version is the one to call out for a labeled opening.
11) Is there an ADA option for lighter opening force on the Q27 floor closer?
Yes, a lighter spring option is orderable on the Q27. It's a build option, not a field adjustment, so specify it at time of order if the opening has to meet a reduced opening force requirement.
12) What is the sealed closer option on the Q27 for?
The sealed option is the one to take where moisture reaches the case, such as an exterior entrance or a wash-down area. The standard case is a Cycolac rust-proof cement case, and the sealed version adds protection for the closer body itself. It's a yes/no choice made at order time.
13) Can the Q27 closer be serviced without taking the door down?
Yes. The bottom arm is surface attached, so the closer body can be pulled from the case without demounting the door. That matters on an occupied entrance where you can't lose the opening for a day. The mortise arm attaches with thru-bolts.
14) Can I fine-tune closing and latching speed on the Q27 after it's installed?
Yes, three separate valves handle closing speed, latch speed, and backcheck independently, and a delay function is included. Backcheck is what protects the door and frame when someone throws it open in a wind-loaded entrance.
15) What are the alternatives to a Rixson Q27 if my opening isn't offset hung?
Two other floor closers we carry are concealed cement-case units rather than 3/4 inch offset: the Dormakaba Dorma BTS80, a heavy duty body-only closer, and the Dorma BTS75V, a Grade 1 body-only unit supplied with cement case and less spindle, in a non-hold-open function. Both are sold as bodies, so the spindle and pivot set are specified separately, where the Q27 ships with its top and intermediate pivot.
16) Can I order a Dorma BTS75V as a drop-in replacement for a Norton Rixson Q27 without touching the door?
Treat them as separate specifications rather than drop-in swaps. The Dorma BTS75V is furnished as a body only with cement case and less spindle, so the spindle and the arm hardware are separate decisions. The Norton Rixson Q27 is an offset hung assembly built around a 3/4 inch offset with a surface-attached bottom arm and a mortise arm thru-bolt attachment, and it is ordered to a specific hand, left or right. Confirm the existing floor case, offset dimension, and hand before substituting either way.
17) For an ADA opening force requirement, which floor closer should I be looking at?
The Norton Rixson Q27 is ordered with a lighter spring option for ADA applications, selected as a yes or no choice at the time of order, and it has an adjustable delay function along with separate valves for closing speed, latch speed and backcheck. The Dorma BTS80 and BTS75V are both floor closer bodies specified by duty and grade rather than by a published spring option, so the Q27 is the direct path when the reduced opening force has to be called out on the order.
18) Which floor closer do I use if the door has to stop hard at a set degree instead of swinging through?
The Norton Rixson Q27 carries a built-in positive dead stop and is ordered to a swing degree of 85, 90 or 95 degrees, so the stop is part of the closer rather than a separate floor or overhead stop. The Dorma BTS75V is a Grade 1 non hold open floor closer body and the Dorma BTS80 is a heavy duty concealed body, both specified without a published dead stop degree, so an opening that needs a fixed stop angle is a straightforward Q27 order.
19) What finishes does the Q27 floor closer come in for matching existing hardware?
Thirteen finishes on the exposed trim: 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 black suede powder and white suede powder. For a building standard, 626 satin chrome and 613 oil rubbed bronze are the two that most commonly match existing lever and pivot trim.
20) If the opening needs a specific finish to match the rest of the building, which floor closer gives the most finish choice?
The Norton Rixson Q27 is ordered in thirteen finishes, including 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, and black and white suede powder coats. The Dorma BTS80 and BTS75V are both supplied as closer bodies, where the visible cover plate is specified separately from the unit itself, so finish matching on those is handled at the cover plate.
