Norton Rixson 5103-90NBC-RH-626 – Frequently Asked Questions

1) Is the Rixson 51 Series offset hung or center hung, and what does that mean for my door?
Offset hung, on a 3/4 inch offset. The pivot sits 3/4 inch in from the edge of the door rather than on the door's centerline, so the door swings from close to its edge instead of pivoting about its middle. That's the arrangement you want where you cannot give up the floor clearance a center hung door needs on both faces. Note it's single acting, so the door swings one direction only, not both.
2) Do I need to specify handing when ordering a Rixson 51 Series floor closer?
Yes, handing matters. The 51 Series is a single acting handed closer and is ordered left hand or right hand. Stand outside the door on the side it swings away from: if the hinges or pivots are on your left it's left hand, on your right it's right hand. Get this wrong and the unit is cut into the floor facing the wrong way, which is not a field fix.
3) Can I get a Rixson 51 floor closer that holds the door open, and at what angle?
Automatic hold open is one of two arm functions on the 51 Series, the other being non-hold open. Hold open is set at 90, 105, or 180 degrees, and the door swings 5 degrees past the hold open point before it catches, so it seats positively rather than drifting off the detent. Pick the angle against what's behind the door: 90 for a door that stops at a wall return, 180 where you want it flat back against the adjacent wall for moving carts or furniture.
4) I need a fire rated floor closer for a labeled door. Can the Rixson 51 do that?
Only in the non-hold open configuration. The fire rated option on the 51 Series is available on non-hold open units only, which is the rule on any labeled opening: a fire door has to be free to close, so it cannot be held open by a mechanical hold open. Certain models carry a UL Listing, identified by the F prefix, with a fire rating for 20 minute labeled doors under the -20 suffix. If you need both a hold open and a labeled door, you need an electromagnetic hold open tied to the fire alarm, not this closer's mechanical hold open.
5) What else do I have to order to install a Rixson 51 Series floor closer?
The floor closer is the bottom half of the job. You also need M19 intermediate pivots at the head of the door, and those are ordered separately, not supplied with the closer. Plan the floor recess and the door prep from the manufacturer templates before anything gets cut, and decide your spindle extension against the finished floor height at the same time.
6) How far will a door on a Rixson 51 Series floor closer open?
Up to 180 degrees, trim permitting. That last part is the catch: the closer allows the full swing, but a push plate, a pull, a wall-mounted stop, or an adjacent return wall can stop the door well short. Check what the door leaf will actually hit at full swing before counting on 180, and if you want the door parked flat, order the 180 degree hold open rather than relying on a stop.
7) Why choose a shallow depth floor closer instead of a standard depth one?
Depth is about what is under the floor. The Norton Rixson 51 Series is a shallow depth unit, which is what you use on upper levels of a multi-story building where you cannot cut a deep pocket into a structural slab or where there is occupied space below. A full depth floor closer needs a deeper recess than that construction allows. On a slab-on-grade ground floor either will work, and depth stops being the deciding factor.
8) Can I adjust the closing speed and the latching on a Rixson 51 floor closer after it's installed?
There are three separate independent valves on the 51 Series, one each for closing speed, latch speed, and backcheck. That means you can slow the general sweep for an accessible opening while keeping the last few degrees quick enough to latch, and set the backcheck to stop the door slamming into a wall when someone throws it open. There's also a delay function and vertical door adjustment for setting the door height after it's hung.
9) What is a floor closer good for that an overhead closer isn't?
Two things. The mechanism is buried in the floor, so there's nothing on the door or frame for someone to attack, hang on, or pull off, which is why floor closers go in schools and public buildings where overhead closers get vandalized. And there's no closer body or arm visible above the door, which is what glass front installers and architects want on an all-glass or narrow-frame entry where an overhead unit has nothing to mount to and would be visible anyway. The trade-off is the install: a floor closer means cutting a recess in the floor, so it's far easier to specify in new construction than to retrofit.
10) Can the spring tension on a Rixson 51 be adjusted for a heavier door or an accessibility requirement?
No. The 51 Series is a fixed size spring, so the closing force is set by the unit and cannot be dialed up or down like an adjustable-size closer. You can tune speed, latch, and backcheck through the valves, but not the spring power itself. Size the opening against the 250 lb door weight rating and the 36, 42, or 48 inch door width before you commit.
11) What is the Rixson 51 floor closer case made of, and will it corrode in the floor?
The case is Cycolac, a rust-proof cement case. That matters more than it sounds, because the case is cast into the floor and stays there for the life of the building. A rust-proof case means water that gets into the recess, from mopping, tracked-in snow, or an entry that sees weather, won't rot the housing out around the closer.
12) What finishes does the Rixson 51 Series come in for matching existing door hardware?
Thirteen finishes on the 51 Series, which covers most of what's already on a building's doors: 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, plus BSP black suede powder and WSP white suede powder. If you're standardizing a property, 626 satin chrome and 613 oil rubbed bronze are the two that most commonly match existing commercial trim. Only the cover plate shows once it's installed, so it's the plate finish you're matching to the pivots and door trim, not the whole unit.
