Norton Rixson 27S-LAP-LH-105 – Frequently Asked Questions

1) What does the LAP designation mean on the Norton Rixson 27 Series floor closer?
LAP is Left Hand Active Pair. On a pair of doors, the 27S-LAP goes under the active (first) leaf of a left hand pair. Handing is built in, not field reversible, so a right hand pair or a right hand single opening needs a different configuration of the 27 Series. Confirm the swing from the outside of the door before ordering.
2) Is the 27 Series floor closer single acting or double acting?
Single acting only. The door swings one direction from the closed position. If the opening needs a door that pushes both ways, such as a restaurant or back-of-house pass door, the 27S-LAP is the wrong choice and a double acting floor closer is required.
3) What goes into the floor for a Rixson 27 closer, and what does the installation involve?
The closer body sits in a cast iron cement case set into the floor, so the slab has to be prepped with a pocket before the pour or cut out on a retrofit. Templates locate the pocket and the mounting holes, the body is set and anchored, and the door hangs on pivots aligned to the spindle. Once the door is hung, closing speed, latch speed and backcheck are adjusted at the closer. Nothing shows overhead when it is done.
4) Is this floor closer rated for high traffic commercial use?
Yes. It is certified to ANSI/BHMA A156.4 Grade 1, the top commercial grade for door controls, and is classified heavy duty for commercial rather than residential service. Cast iron body with stainless steel components handles the cycle counts and the moisture you get at an entrance.
5) I already have a floor pocket and cement case in the slab - do I need the full Rixson 27 Series assembly or just a closer body?
If the cement case is sound and correctly located, you want a body-only closer rather than a complete case assembly. The Dormakaba BTS80 is sold as a concealed floor closer body only and is a heavy duty unit, the same duty level as the Norton Rixson 27 Series. The 27 Series is supplied with a cast iron cement case, which is what you want when the floor is being cut fresh or the existing pocket is damaged. Confirm the existing case dimensions and spindle centerline before committing either way, since cases are not interchangeable between manufacturers.
6) Does the Rixson 27 floor closer hold the door open?
No hold open. It is a non hold open closer, so the door returns to closed every cycle. For an opening that has to be propped during deliveries or moves, you would need a hold open version or a separate floor stop and holder. Among the floor closers we carry, the Dorma BTS75V is also listed as NHO, non hold open.
7) Will the Rixson 27 work on an all glass entrance door?
It is suited to wood, metal or glass doors, so a glass leaf is within scope as long as it stays under 300 lb and about 4 feet wide. On glass you also need the matching top and bottom patch fittings and pivot set for the door itself, which are separate from the closer body.
8) Why choose a floor closer instead of an overhead closer on a commercial entrance?
Two reasons drive it. Appearance: the whole mechanism is concealed in the floor, so there is no arm or body across the head of a storefront or a full glass opening. Load: a floor closer carries and controls a heavy leaf, up to 300 lb here, through a pivot rather than hanging the control off the frame. The tradeoff is the slab work. An overhead closer is a far simpler retrofit on an existing opening where cutting the floor is not practical.
9) Can the closing speed be tuned after install for a windy entrance?
Yes. Closing speed, latch speed and backcheck are each adjustable at the closer, so you can slow the main sweep, set the latch to pull the door into the strike, and use backcheck to stop the leaf from being thrown open into a wall on a gusty exterior opening.
10) Will a Dorma BTS75V work on a double acting center hung door if the Rixson 27 Series will not?
The Norton Rixson 27 Series is a single acting closer, built for doors that swing one direction only, and the Left Hand Active Pair version is handed to the active leaf. The BTS75V is a Grade 1 non-hold-open floor closer supplied with cement case, and floor closer bodies of that type are commonly specified on center hung applications - but the swing behavior on any floor closer is determined by the body and spindle combination ordered, so confirm the required swing with the manufacturer's spindle and top pivot selection rather than assuming from the series number.
11) My opening is a fire rated door - can I use the Dorma BTS80 in place of the Rixson 27 Series?
The BTS80 is designated as not fire rated, so it should not be specified where a labeled opening requires a fire rated closer. The Norton Rixson 27 Series is certified to ANSI/BHMA A156.4 Grade 1 for commercial use, but fire door assemblies are approved as a whole, so verify the closer, pivots and door label together with the authority having jurisdiction before ordering either unit for a labeled opening.
12) I need a floor closer that holds the door open - is the Rixson 27 Series or a Dorma unit the right pick?
Neither of these is a hold open closer. The Norton Rixson 27 Series has no hold open feature, and the Dormakaba BTS75V is specified as NHO, non hold open. If the opening needs the door to stand open, that has to be handled by a hold open variant of the closer series or by a separate floor stop and holder, and it should be checked against the occupancy requirements - hold open is generally not permitted on a labeled fire door without a release device.
13) For a high traffic entrance, does the Dorma BTS80 give the same duty level as the Norton Rixson 27 Series?
Both are classed heavy duty. The Dormakaba BTS80 is a heavy duty concealed floor closer, and the Norton Rixson 27 Series is heavy duty as well, rated for doors up to 300 lb and widths typically to 4 ft, with cast iron body and stainless steel components and adjustable closing speed, latch speed and backcheck. The deciding factor between them is usually supply scope - the BTS80 is a body only unit, while the 27 Series comes with its cast iron cement case.
