Norton Rixson 28S-LAP-RH-105 – Frequently Asked Questions

1) Will the Rixson 28 Series floor closer handle a 300 lb door?
Yes. The Rixson 28 Series heavy duty floor closer is rated for doors up to 300 lb (136 kg) and 4 feet (1219 mm) in width, which covers most heavy commercial entrance leaves. Past either of those numbers you are outside what the 28 Series is rated for and need a larger capacity closer.
2) Is the Rixson 28 Series single acting or double acting?
Single acting. The 28 Series swings one direction only, so it suits a door with a stop or frame rabbet on one side. A center-hung double acting opening, like a pair of traffic doors swinging both ways, needs a double acting floor closer instead.
3) What handing and swing degree do I have to specify when ordering a Rixson 28 floor closer?
Two choices on the order. Handing is left hand or right hand, and maximum swing is 90 degree or 105 degree. All four combinations are non hold open. Pick 90 degree where a wall, return, or adjacent partition stops the leaf short, and 105 degree where the opening is clear and you want wider travel for carts or gurneys.
4) Does the Rixson 28 Series meet a Grade 1 spec for a school or hospital job?
It is certified to ANSI/BHMA A156.4, Grade 1 and classified commercial, heavy duty. A156.4 is the door controls standard, and Grade 1 is the highest cycle and performance tier in it, which is what institutional specs normally call for on main entrances and high traffic corridors.
5) I have a pair of doors. Do I need one Rixson 28 closer or two?
One floor closer per leaf. The 28 Series is a single acting closer handed left or right, so a pair takes a left hand unit on one leaf and a right hand unit on the other, each within the 300 lb and 4'0" per-leaf rating. On a pair with an active and inactive leaf, the active leaf gets the closer matched to its swing direction.
6) What is a comparable heavy duty concealed floor closer to the Norton Rixson 28 Series?
The Dorma BTS80 is a concealed floor closer body rated Heavy Duty, the same duty level the Norton Rixson 28 Series carries. The 28 Series is a single acting floor closer certified to ANSI/BHMA A156.4, Grade 1 and supplied with a cast iron cement case; the BTS80 is sold as a body only, so the case and related floor components are handled separately. Confirm the floor prep and spindle arrangement of whichever you specify matches the existing pocket before ordering.
7) Which floor closer matches the Norton Rixson 28 Series on Grade 1 and non hold open operation?
The Dorma BTS75V is listed as Grade 1 with an NHO non hold open function, which lines up with the Norton Rixson 28 Series: it is ANSI/BHMA A156.4, Grade 1 and has no hold open feature, with every 28 Series offered as a non hold open model in 90 degree and 105 degree swings. The BTS75V ships with a cement case less spindle, so the spindle is ordered separately.
8) Is a cement case included with the Rixson 28 floor closer, or do I buy it separately?
The cover type is a cast iron cement case, so the closer is set in floor as a cast iron cement case assembly. That matters at rough-in: the case gets placed before or during the slab pour or in a cut pocket, so coordinate with the concrete work rather than treating this as a finish-trade item.
9) What adjustments does the Rixson 28 floor closer give me for tuning door speed?
Three independent adjustments: closing speed, latch speed, and backcheck. Closing and latch speed let you slow the sweep for accessibility and still get positive latching, and backcheck cushions the leaf on a hard push so wind or traffic does not slam it into a wall.
10) Why use a floor closer instead of an overhead closer on a heavy entrance door?
A floor closer carries the door weight down into the slab rather than hanging it off the frame, which cuts frame stress on a heavy leaf, and the mechanism is concealed in the floor so nothing shows at the head. That is why the 28 Series suits glass and all-glass-look entrances and lobbies. An overhead closer is the cheaper, simpler call when the header can take the load and appearance is not the driver, and it does not require cutting the floor.
11) What other heavy duty concealed floor closers could I use instead of the Rixson 28?
Two Dormakaba options sit in the same class. The Dorma BTS80 is a heavy duty concealed floor closer supplied as body only, so you source the case and spindle separately. The Dorma BTS75V is a Grade 1 non hold open floor closer supplied with cement case but less spindle. Both are body-only style purchases, which is the practical difference from ordering the 28 Series as a configured closer.
12) Can I retrofit a Rixson 28 floor closer into an existing slab?
Yes, but it is concrete work, not a swap. The cast iron cement case has to sit in a floor pocket cut to the template dimensions and depth, aligned to the pivot points, and sealed and weatherproofed. Confirm the slab has the depth and structural support for the case and that drainage is addressed before you commit to the opening.
13) If I need a floor closer with a hold open function, is the Norton Rixson 28 Series the right choice?
No. The Norton Rixson 28 Series has no hold open feature and all configurations are non hold open in 90 degree or 105 degree swing. The Dorma BTS75V is also an NHO non hold open closer, so it is not an alternative for that requirement. For a hold open opening, specify a floor closer whose function is stated as hold open rather than either of these.
14) I only need to replace the closer mechanism in an existing floor pocket - what is a body only option next to the Norton Rixson 28 Series?
The Dorma BTS80 is offered as a concealed floor closer body only, which suits a retrofit where the cement case is already in the floor and staying. The Norton Rixson 28 Series is described with a cast iron cement case, so it is set up for a full installation including the case rather than a mechanism swap. Verify the existing case dimensions accept the replacement body before ordering.
15) What is the Rixson 28 closer body made of and will it survive a high traffic entrance?
Cast iron body with stainless steel components, set in a cast iron cement case. That combination is what carries the Grade 1 heavy duty rating and is why it gets specified for lobbies, schools, hospitals, and municipal entrances where the door cycles all day.
