Norton Rixson L27-180N-RH626 – Frequently Asked Questions

1) Will the Norton Rixson L27-180 floor closer work on a lead-lined radiology door?
That is exactly what the L27-180 is built for. It's a 3/4 inch offset-hung floor closer for lead-lined interior or exterior doors, and the mounting screw holes are spaced to straddle the lead lining so fasteners bite into the door frame structure rather than through the shielding. Door weight capacity runs to 1500 lbs, which covers the mass a lead-lined door carries. The offset configuration accommodates 1-3/4 inch thick doors.
2) Is the L27-180 a center-hung or offset-hung floor closer?
Offset hung, at 3/4 inch offset. That matters because center-hung and offset-hung are not interchangeable: an offset-hung closer puts the pivot point 3/4 inch in from the door edge, and the floor prep, top pivot, and door edge prep all follow that geometry. If the existing opening is prepped center-hung, this unit will not drop into it. It's also single acting, so it swings one way only, not a double-acting traffic door.
3) What else do I need to order with the Norton Rixson L27-180 besides the closer itself?
The L27-180 comes with the L180 top pivot. If the door is 60 to 90 inches in height you also need ML19 intermediate pivots, and those are ordered separately. Beyond pivots, you are specifying on the order form: handing (left or right), finish, arm function (automatic hold open or non-hold open), whether you want the lighter ADA spring, whether the closer is sealed, and any extended spindle length (1/2, 1, 1-1/2, or 2 inch) if the finished floor sits above the cement case.
4) Does the Rixson L27-180 hold the door open, and how do I stop it swinging past 90 degrees?
Two separate things here. Hold open is an ordering choice: the arm function comes as automatic hold open or non-hold open, so pick the one you want. Stopping the swing is the built-in positive dead stop, specified at 85, 90, 95, or 105 degrees. Without a dead stop spec the unit opens a full 180 degrees, which is useful for moving beds and equipment through but will let the door hit an adjacent wall if nothing arrests it.
5) Is the Rixson L27-180 Grade 1 and rated for high traffic entrances?
Certified to ANSI/BHMA A156.4 Grade 1 and rated high traffic, with an extra heavy duty classification. Grade 1 under A156.4 is the top commercial tier for door closers, which is the line most institutional and government specs draw. Construction behind that rating is a cast iron cement case with a hardened one-piece steel spindle plus an additional thrust bearing for load capacity.
6) Is handing important when ordering a Rixson L27-180 floor closer?
Handing matters here. The L27-180 is single acting and built left hand or right hand, so the wrong hand is the wrong part, not a part you flip in the field. Determine hand from the outside of the door, standing where the hinges or pivots are on the far side, and order to match.
7) What is the difference between the Norton Rixson L27-180 floor closer and the Dorma BTS75V floor closer?
Both are ANSI Grade 1 floor closers, but they are built for different openings. The L27-180 is an extra heavy duty, offset hung unit rated for doors up to 1500 lbs, single acting, with a cast iron cement case and a delay function, and it is ordered in either Automatic Hold Open or Non-Hold Open arm function. The Dorma BTS75V is supplied as a closer body only with cement case and less spindle, and is offered in NHO non hold open function only. If the opening needs a hold-open arm or a lead-lined door weight capacity, the L27-180 is the one that covers it; if the existing spindle and hardware are staying in place, the BTS75V body is the narrower replacement.
8) I need a floor closer with a lighter spring for ADA closing force. Which of these can be ordered that way?
The Norton Rixson L27-180 is ordered with a Lighter Spring (ADA) option selected yes or no, and it has a delay function plus separate independent valves for closing speed, latch speed, and backcheck. The Dorma BTS75V is offered in NHO non hold open function, and the Dorma BTS80 is a concealed body-only unit rated Heavy Duty. For an opening where reduced opening force is part of the spec, the L27-180 is the one with that choice built into the order.
9) Can a Rixson L27-180 floor closer be adjusted to meet ADA opening force on a heavy door?
There is a lighter spring option you specify at order time on the L27-180, which is the lever you have for reducing opening force. Separate independent valves control closing speed, latch speed, and backcheck, and the closer also has a delay function, so you can slow the cycle to give someone time to get through. Specify the lighter spring up front; it is a build option, not a field adjustment.
10) Which floor closer should I use if I only need to replace the closer body and the cement case is already in the floor?
The Dorma BTS80 and the Dorma BTS75V are both supplied as closer bodies only, and the BTS75V comes with cement case and less spindle. The Norton Rixson L27-180 is a complete extra heavy duty offset hung unit with a cast iron cement case and a hardened one-piece steel spindle, ordered with handing, finish, and arm function selected, so it is the choice when the floor is being cut fresh or the whole assembly is coming out.
11) Do any of these floor closers carry a fire rating?
The Dorma BTS80 is listed as not fire rated. The Norton Rixson L27-180 is certified to ANSI/BHMA A156.4 Grade 1 for commercial high traffic use, with a cast iron cement case and extra heavy duty construction for doors to 1500 lbs. For a rated opening, confirm the full door, frame, and hardware assembly listing before specifying either one.
12) What is the sealed closer option for, on a floor closer installed in concrete?
Sealing protects the closer body where water can reach it: an exterior entrance, a washdown area, a garage or dock slab that drains toward the case, or any floor pocket that collects moisture. The L27-180 is offered sealed or unsealed. If the opening is interior and dry, the unsealed build is the normal specification.
13) Can I get a Rixson L27-180 floor closer cover to match brass or bronze door hardware in a lobby?
Thirteen finishes are offered on the L27-180: 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. That covers matching existing 626 or 613 hardware across a building, which is usually what decides it when a property manager is standardizing a set of openings.
14) Can the closing and latching speed be adjusted after the Rixson L27-180 is set in the floor?
Yes, through three separate independent valves: closing speed, latch speed, and backcheck. That means you can slow the main sweep without losing latching force, and the backcheck valve cushions the door before it reaches full open so a heavy lead-lined leaf does not slam into the stop. A delay function is also included. All of it is valve adjustment after the case is in, which is why the cast iron case gets set carefully the first time.
