Norton Rixson 27N-LAP-RH-90 – Frequently Asked Questions

1) Does the Norton Rixson 27 Series floor closer hold the door open?
No. The 27 Series floor closer is a non-hold-open closer, so the door returns to the closed position every cycle. If you need a door that parks open at a set degree, this isn't the unit for it. Closing speed, latch speed and backcheck are all adjustable, so you can slow the swing down without holding it open.
2) Will a Rixson 27 floor closer work on a double-acting door that swings both ways?
No. The 27 Series is a single acting closer, meaning it controls a door that swings one direction only. For a center-hung door that swings in and out, you need a double-acting floor closer instead. Handing matters on this one too, since each unit is ordered left hand or right hand.
3) How do I figure out whether I need the left hand or right hand Rixson 27 floor closer?
Stand outside the door, on the side it swings away from you. If the hinges (or pivots) are on your left, it's left hand; on your right, it's right hand. The 27 Series is built both ways, and the closer is not field-reversible in the way a surface closer is, so the handing has to be correct on the order. On a pair of doors, each leaf is handed separately.
4) What is the difference between the 90 degree and 105 degree version of the Rixson 27 closer?
That's the maximum swing the closer allows before it stops the door. Pick 90 degrees where a wall, return, or adjacent door limits travel; pick 105 degrees where you want a wider opening for carts, gurneys or furniture moves. Both are offered in left hand and right hand. Order the degree that matches the physical clearance at the opening, since the stop is built into the unit.
5) I need a non-hold-open floor closer for a pair of entrance doors. Do both leaves take the same unit?
No. Each leaf takes its own closer, handed to that leaf, so a pair typically means one left hand and one right hand unit. Both leaves also need the same swing degree, 90 or 105, unless the openings differ. The 27 Series is non-hold-open across the board, so a pair of them will both self-close.
6) What is the closest equivalent to the Norton Rixson 27 Series floor closer from another manufacturer?
The Dormakaba BTS75V is the nearest peer. Like the Norton Rixson 27 Series, it is a concealed in-floor closer rated Grade 1, and it ships with a cement case, matching the 27 Series cast iron cement case construction. The BTS75V is a non hold open function, which lines up with the 27 Series, which has no hold open feature. The BTS75V is supplied as a body only, less spindle, so the spindle and any top pivot or arm hardware are ordered separately; the 27 Series is ordered by handing and swing degree instead.
7) How does the Dorma BTS80 compare with the Norton Rixson 27 Series for a high traffic entrance?
Both are heavy duty concealed floor closers. The Dorma BTS80 is rated heavy duty and is listed as not fire rated, and it is sold as a body only, so the cement case is a separate purchase. The Norton Rixson 27 Series is also heavy duty and is supplied with a cast iron cement case, is single acting, and carries ANSI/BHMA A156.4 Grade 1. If you are replacing an existing floor closer and reusing the case already in the slab, a body only unit like the BTS80 is the form factor to look at; if the floor is being cut fresh, the 27 Series brings its own case.
8) Is a floor closer or a surface mounted closer better for a high traffic commercial entrance?
A floor closer like the Rixson 27 puts the whole mechanism in the floor under the door, so nothing shows on the door or frame. That's why it gets specified on glass entrances, lobbies and storefronts where the look matters, and on heavy doors where the closing force is better taken at the pivot. The tradeoff is the install: you have to cut the floor and set a cement case, which is why surface closers stay the default on retrofits where the slab is already poured and finished.
9) What do I need to prepare in the slab before installing a Rixson 27 floor closer?
The closer sits in a cast iron cement case set into the floor, so the slab has to be cut to accept the case at the correct depth, dead level, with structural support and drainage handled. Use the manufacturer template to lay out the case so it lines up with the door swing path before the pour or patch goes in. Once the case is set and the floor finished, the position is fixed, so the layout is the step that decides whether the door hangs true.
10) Can I use this floor closer on a glass door, or is it only for wood and metal?
The 27 Series is used with heavy commercial doors in wood, metal and glass. For a glass leaf you'll also need the matching top and bottom patch fittings and a spindle to suit the door, since the closer itself controls the door through the pivot point rather than attaching to the face.
11) What else could I use instead of a Rixson 27 if I need a floor closer body for an existing cement case?
ZenSupply carries the Dormakaba Dorma BTS80, a heavy duty concealed floor closer sold as a body only, which is the usual route when the case is already in the floor and only the mechanism has failed. There's also the Dorma BTS75V, a Grade 1 non-hold-open floor closer offered with cement case and less spindle. The Rixson 27 by contrast is a Grade 1 heavy duty unit supplied with a cast iron cement case, so it suits a new cut rather than a body swap.
12) Does a fire rated opening rule out any of the concealed floor closers?
The Dorma BTS80 is listed as not fire rated, so it should not be specified where a labeled door assembly is required. The Norton Rixson 27 Series is certified to ANSI/BHMA A156.4 Grade 1 for commercial service. For a labeled opening, confirm the listing of the complete door, frame, and closer assembly with the authority having jurisdiction before ordering either.
13) What is the difference between ordering the Norton Rixson 27 Series and a body only floor closer like the Dorma BTS80?
The Norton Rixson 27 Series is selected by handing and swing degree, in left hand and right hand at 90 degrees or 105 degrees, and comes with a cast iron cement case for in floor installation. The Dorma BTS80 is catalogued as a closer body only, and the Dormakaba BTS75V is a closer body with cement case but less spindle. On a body only order you are responsible for confirming the existing case and spindle length; on the 27 Series you are confirming the handing and the degree of swing the opening allows.
14) Will a cast iron floor closer hold up in an exterior entrance that gets weather and grit?
The 27 Series is built for it: cast iron cement case with stainless steel components, rated heavy duty and called out for both interior and exterior openings. The reason floor closers care about drainage during install is exactly this, water that reaches the case has to have somewhere to go. Grade 1 under A156.4 is the durability tier you want on a main entrance that cycles all day.
