Norton Rixson PH27N-LAP-RH-105 – Frequently Asked Questions

1) Will the Norton Rixson PH27 floor closer work on a center-hung door?
No. The PH27 is built for offset-hung doors with the 3/4 inch standard offset, single acting. If your door pivots on center, this is the wrong closer and the pivot geometry will not line up. Confirm the door is hung offset before you order.
2) Do I have to specify left hand or right hand when ordering a PH27 floor closer?
Yes, and it matters more here than on a surface closer. The PH27 is non-reversible, so it is ordered as either Left Hand or Right Hand and cannot be flipped in the field. Stand outside the door, look at the hinge side: hinges on your left is a left hand door. Order the wrong hand and it goes back.
3) Does the PH27 floor closer meet ADA opening force requirements?
That is what the PH27 Series was built around. It is the Physically Handicapped version, engineered for barrier-free opening force with reduced opening resistance, and it carries ANSI/BHMA A156.4 Grade 1. Independent sweep and latch speed valves let the installer dial closing speed so the opening meets accessibility requirements after the door is hung.
4) What floor prep does a concealed floor closer like the PH27 need?
The closer body sits entirely in the floor inside a cast iron cement case, so the slab has to be excavated and the case set and anchored in concrete before the door goes up. That makes it a new-construction or full-renovation item, not a swap you do on a Friday afternoon. Use the manufacturer templates to lay out the case against the door pivot points, since the offset has to be right before the concrete goes in.
5) Can I use the PH27 on a double-acting door that swings both ways?
No. The PH27 is single acting, so it controls a door swinging one direction only. A door that swings in and out both ways needs a double-acting floor closer, and putting a single-acting unit under it will not work.
6) What is the closest equivalent to the Norton Rixson PH27 floor closer from another manufacturer?
The Dorma BTS75V is the nearest peer: a concealed floor closer supplied as a body with cement case, less spindle, and rated Grade 1, the same grade class as the PH27's ANSI/BHMA A156.4 Grade 1 rating. The BTS75V is a non-hold-open function, which matches the PH27 configuration that ships without a hold-open feature. Confirm the offset your opening uses before ordering either, since the PH27 is built for 3/4 inch standard offset single-acting doors.
7) I need a floor closer that holds the door open. Is the PH27 or a Dorma unit the right call?
The Norton Rixson PH27 is offered in hold-open (HO) and non-hold-open (NHO) versions, so the hold-open requirement is met by selecting the HO version at the time of order. The Dorma BTS75V is listed as non-hold-open only, so it will not satisfy a hold-open opening. Specify the PH27 HO version when the door has to stand open.
8) Does the PH27 floor closer hold the door open?
The PH27 is offered both ways, hold-open (HO) and non-hold-open (NHO), so the function is an ordering decision. Note that the version stocked here is the non-hold-open configuration. On an accessible egress or a fire-rated opening, hold-open is usually not what you want unless it is tied to a release device.
9) Should I use a floor closer or an overhead closer on a glass or aluminum entrance?
A floor closer like the PH27 is the choice when there is no header to mount to, when the door is heavy (this one handles up to 450 lb), or when the architect wants nothing visible above the opening. The tradeoff is the slab work: the cement case is buried in the floor. An overhead surface closer costs far less labor and can be replaced without touching concrete, so if you have a solid header and no aesthetic constraint, go overhead. Once the case is in the floor, you are committed to floor closers on that opening.
10) What other concealed floor closers can I use instead of the Norton Rixson PH27?
Two Dormakaba options are the common alternates. The Dorma BTS75V ships as a body with cement case, less spindle, and is Grade 1 non-hold-open. The Dorma BTS80 is a heavy duty body only. Both are body-only orders, so the spindle and cover plate come separately, where the PH27 is specified as an ADA offset-hung package. If you are replacing an existing Dorma case in the floor, staying with the BTS family avoids re-cutting the slab.
11) Is the PH27 floor closer rated for a high traffic hospital or school entrance?
Heavy duty, commercial, and ANSI/BHMA A156.4 Grade 1, which is the top grade in the floor closer standard and what a spec writer will call for on a public building entrance. Cast iron cement case construction is the part that survives the traffic, since the working body is protected in the slab rather than hanging off the door.
12) Difference between the Dorma BTS80 and BTS75V floor closers?
Both are concealed floor closer bodies. The BTS80 is listed as body only at a heavy duty level with no fire rating. The BTS75V is supplied with a cement case, less spindle, is rated Grade 1, and is a non-hold-open function. If you need the case included in the same order, the BTS75V covers it; the BTS80 body will need the case sourced alongside it.
13) Is a floor closer body like the Dorma BTS80 a drop-in replacement for a whole PH27 installation?
No. The BTS80 is catalogued as a body only, meaning it is the closer mechanism without the case, so it suits replacing a worn mechanism inside a case that is already set in the floor. The PH27 is a complete concealed unit with a cast iron cement case, which is what you order when the floor cavity is being excavated and anchored new. Matching the existing case is the deciding factor: a body swap only works if the case in the floor accepts that body.
14) Can I adjust the closing speed on the PH27 after it is installed in the floor?
Yes. Independent sweep and latch speed valves are adjustable, so you can slow the sweep for accessibility and still get enough latch speed to close the door into the frame. That is done at final adjustment after the case is set and the door is hung, and it is how the opening is tuned to meet the accessible force and closing requirements.
