Norton Rixson PH28S-LAP-RH-90 – Frequently Asked Questions

1) Do I have to specify handing when ordering a Rixson PH28 floor closer?
Yes, handing is not field-reversible on the order form. The PH28 is offered left hand or right hand, and every combination is built one way or the other. Stand outside the opening, on the side the door swings away from: hinges on the left is left hand, hinges on the right is right hand. Get it wrong and the closer will not drop into the prep correctly.
2) What swing degrees can I get on the Rixson PH28 floor closer?
Three: 90, 95, and 105 degrees. The number is the maximum door opening the closer allows, so pick it off the obstruction beside the opening. A wall return, adjacent glass, or a side light close to the leaf usually forces the 90 degree build; 105 is the choice where the door has room to swing clear. Each degree is available in both left and right hand.
3) Is the Rixson PH28 floor closer ADA compliant for barrier-free entrances?
It's built for ADA openings, with reduced opening force and adjustable sweep and latch speeds so you can dial the closing rate to meet the accessibility requirement on site. The two speeds adjust independently, which is what lets you slow the sweep for an accessible entrance without letting the door fail to latch.
4) Is the Rixson PH28 rated Grade 1 for a school or hospital entrance?
Certified to ANSI/BHMA A156.4, Grade 1, the highest grade in the floor closer standard, and specified as heavy duty commercial. That's the grade most institutional specs call for on a main entrance, so it will satisfy a Grade 1 line item on healthcare, education, or government drawings.
5) What floor prep does the Rixson PH28 need, and what comes with it?
The closer body sets into a cast iron cement case that gets poured or set into the floor slab under the door, so this is a slab-cut job, not a surface mount. You cut the cavity from the manufacturer's template, set the case in line with the pivot point, then drop the body in and adjust sweep and latch. Nothing hangs overhead, which is the reason most people choose it. Plan the prep before the floor goes down where you can, retrofitting into finished concrete means coring.
6) Floor closer or overhead closer for a glass front entrance?
A floor closer like the PH28 puts all the hardware in the slab, so there's no arm or body on the door face or the head. On an all-glass or narrow-stile aluminum entrance that's often the only clean option, and it's what most storefront specs call for. An overhead closer is cheaper and far easier to service, since a floor closer means opening the slab to replace. If the door is a standard hollow metal or wood leaf in a frame with a header to mount to, an overhead is usually the more practical choice.
7) Can I use the Rixson PH28 to standardize the entrances across a building?
For offset-hung single-acting openings, yes, and that's the usual reason it gets specified across a portfolio. One heavy duty Grade 1 model covers doors up to 450 lb, and you vary only the handing, swing degree, and hold open choice per opening. Doors that swing both directions or hang on center pivots fall outside it and need a different closer.
