Norton Rixson 27-180N-RH626 – Frequently Asked Questions

1) Will the Norton Rixson 27-180 floor closer handle a heavy exterior storefront door?
The 27-180 is rated for doors up to 450 lbs and is built for both interior and exterior openings, with a Cycolac rust-proof cement case for the buried half. It is an offset-hung closer, so the door has to be prepped for 3/4 inch offset hanging rather than center-hung pivots. Single acting only, so it swings one direction.
2) How far will a door on a Rixson 27-180 floor closer open?
180 degrees maximum. The spindle is a hardened one-piece steel unit with a built-in positive dead stop so the door cannot swing past the degree you set it for, but Norton Rixson still calls for an auxiliary floor or wall stop on the opening. Budget for that stop as a separate line item, it does not come with the closer.
3) Do I need to order intermediate pivots separately for a tall door with the Rixson 27-180?
Yes, and they are a separate order. M19 intermediate pivots are called for on doors 60 to 90 inches tall, with another pivot for each additional 30 inches of height. A floor closer carries the bottom of the door and the top pivot carries the head, but a tall leaf needs the intermediate to keep it from racking.
4) Does the Rixson 27-180 have a hold open, and should I get it?
Both ways. The closer is offered in automatic hold open and non-hold open arm functions. Automatic hold open catches the door at a set degree, useful for a receiving door or a corridor that is propped through a moving day. Non-hold open is what you want on any opening that has to close and latch every time, and it is the version to spec if the door is part of a smoke or fire separation.
5) Can the closing force on a Rixson 27-180 be set light enough for accessible openings?
There is a lighter spring option, ordered as a build choice rather than adjusted in the field, for openings where the pull force has to come down. On the hydraulic side the 27-180 has separate independent valves for closing speed, latch speed, and backcheck, plus a delayed action function, so you can slow the sweep and give someone time through the door without touching the spring.
6) What is the difference between a floor closer and a surface mounted door closer for a heavy entrance?
A floor closer like the 27-180 buries the hydraulic body in a cement case in the slab, so nothing shows at the head of the door and the closer carries the weight of the leaf, up to 450 lbs here. That is why it is the standard choice on all-glass and heavy aluminum storefront entrances where there is no top rail to mount to and where a surface closer would look wrong. A surface closer is cheaper to install and serviceable without opening the floor, but it cannot support the door and it needs a frame or door face to land on. Once the slab is poured, switching from one to the other is expensive, so decide before concrete.
7) What other floor closers could I use instead of the Rixson 27-180?
Two Dormakaba options sit in the same class. The Dorma BTS75V is a Grade 1 floor closer body, non-hold open, supplied with a cement case and less spindle, so you pick the spindle to suit the floor buildup, the same problem the extended spindle solves on the Rixson. The Dorma BTS80 is a heavy duty concealed floor closer body only, and it is not fire rated, which rules it out if your opening is in a rated assembly. Neither Dorma is offered as an automatic hold open the way the 27-180 is, so if you need the door to catch open, stay with the Rixson.
8) I am replacing a floor closer in an existing building, is the Rixson 27-180 a body-only swap?
The 27-180 is an offset hung, single acting closer at 3/4 inch offset, so it drops in cleanly only where the existing case and door prep are already 3/4 inch offset for the same hand. If you are pulling a body out of a sound case and the geometry matches, the Dorma BTS80 and BTS75V are also sold body only for that kind of swap. Where the old unit was center hung or double acting, the floor prep is different and you are into cutting the slab, not swapping a body.
9) For standardizing floor closers across a facility, does the Norton Rixson 27-180 or the Dorma BTS80 give more consistent hardware across openings?
Both are heavy duty floor closers. The Dorma BTS80 is catalogued as a heavy duty concealed floor closer body only, with fire rating stated as No. The Norton Rixson 27-180 is a commercial heavy duty closer certified ANSI/BHMA A156.4 Grade 1, and it is configured within one series across left and right handing, hold open and non-hold-open arm functions, a lighter ADA spring option, and thirteen finishes from 605 bright brass through BSP black suede powder. For an MRO or institutional buyer keeping one series on the shelf for offset-hung, single-acting doors up to 450 lbs, the 27-180 covers the variation inside a single family; the BTS80 is the choice where the specification already calls for a Dorma concealed body.
10) Will the Rixson 27-180 match the finish on the rest of my door hardware?
Thirteen finishes cover most standard hardware schedules: 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. Only the exposed cover and arm show, so 626 satin chrome or 613 oil rubbed bronze to match levers and pulls is the usual call across a building.
11) What does the sealed closer option on the Rixson 27-180 do for me?
The sealed version is the one to spec where water gets into the floor pocket, an exterior entrance, a garage or wash-down area, a pool deck, or anywhere the slab is mopped hard. The standard case is already Cycolac and rust-proof, but the sealed build protects the closer body itself where the pocket can fill. It is a yes or no choice at order time, not a field addition.
