Dormakaba BTS75VA-NHO-74010-626 – Frequently Asked Questions

1) Will the Dorma BTS75VA floor closer work on a double acting aluminum door?
Yes. The BTS75VA is non-handed and works on both single acting and double acting doors, so one unit covers a swing-both-ways aluminum storefront door as well as a one-way opening. Because it is a floor-concealed closer, the body sits in the floor under the door and the spindle drives the pivot point, which is why no left or right hand version is needed.
2) Do I have to order a specific spring size for the BTS75V, or is it adjustable on site?
Spring power is adjustable on the unit from size 1 through size 4, so you set closing force after the closer is in the floor rather than picking a fixed size when you order. That range covers both light barrier-free openings and heavier exterior storefront doors.
3) What do I need to decide before ordering a BTS75VA floor closer?
Three choices: hold open, barrier-free, and finish. Hold open is offered as 90 degree hold open, 105 degree hold open, or no hold open. The barrier-free option is a yes or no selection. Cover plate and spindle finishes are 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 625 bright chrome, and 626 satin chrome.
4) Can a floor closer be installed in a thin concrete slab?
The BTS75V has a compact body that can go into thin slab subfloor construction where a larger cement case closer will not fit. That is the main reason this series gets specified on retrofits over an existing slab.
5) Will the BTS75V work with my floor covering and threshold height?
Yes, within the spindle range. The series uses interchangeable spindles so the closer can be set for different floor coverings and threshold conditions, from bare concrete to tile or carpet buildup. You select the spindle to suit the finished floor height at the pivot.
6) Should I use a BTS75V floor closer or an offset hung floor closer like the Rixson 20 or 127?
The BTS75V is a center-hung style concealed floor closer for aluminum doors and frames, non-handed and rated Grade 1 heavy duty. If your door is hung on a 3/4 inch offset pivot rather than center pivot, you need an offset closer instead: the Norton Rixson 20 Series is a 3/4 inch offset hung closer with 180 degree swing in standard duty, and the Norton Rixson 127 Series is a heavy duty 3/4 inch offset closer for deep reveal openings. Match the closer to how the door is pivoted, not the other way around.
7) What is the closest heavy duty Grade 1 alternative to the Dorma BTS75VA floor closer?
The Norton Rixson H28 Series concealed floor closer (NOR-SC-H28S-105-587) is the nearest match on rating, also carrying a heavy duty, Grade 1 classification like the BTS75VA. The difference is the hanging method: the H28 is built for offset-hung doors, while the BTS75VA is a non-handed double acting closer for aluminum doors and frames with adjustable spring size 1 to 4 and mechanical backcheck. If the opening is center-hung aluminum, stay with the BTS75VA; if the door is offset-hung on a pivot set back from the jamb, the H28 is the correct body.
8) Is the Dorma BTS75V ADA compliant?
The BTS75V is recorded as not ADA compliant. It is a Grade 1 heavy duty commercial closer with spring power adjustable from 1 to 4, and barrier-free versions are offered, but do not specify it against an ADA opening force requirement on that basis alone.
9) Does the BTS75V have backcheck to stop the door slamming into the wall?
It has mechanical backcheck, which cushions the door near the end of the opening swing. On a windy exterior storefront that is what protects the glass and the frame.
10) Is the BTS75V rated for high traffic commercial entrances?
It is classified commercial, heavy duty, and ANSI/BHMA Grade 1 certified, which is the top grade for door closers. The series is built to keep working in adverse weather and heavy traffic, which is why it turns up on retail and office storefront entrances.
11) If I am standardizing floor closers across a building, can I order the same BTS75VA for doors that hold open and doors that do not?
Same closer, different option. The BTS75VA is offered with 90 degree hold open, with 105 degree hold open, or with no hold open at all, and every one of those is available in all five finishes: 605, 606, 613, 625 and 626. So you can keep one model and one finish across the building and vary only the hold open behavior door by door.
12) I ordered a Norton Rixson 25 Series cement case - does that replace the BTS75VA?
No. The Norton Rixson 253000-PKG is a floor closer cement case in heavy-duty galvanized steel - the box that gets set in the slab, not the closer mechanism. The BTS75VA is the operating closer itself, with adjustable spring power size 1 to 4, mechanical backcheck, and non-handed operation for single and double-acting doors. A cement case is a companion item for its own closer family, not a substitute for a closer body.
13) For a barrier-free aluminum entrance, should I specify the BTS75VA or the Norton Rixson H28?
The BTS75VA is configurable for barrier-free openings, with adjustable spring power from size 1 to 4 covering both barrier-free and non-barrier-free doors, and it is non-handed for single and double-acting aluminum doors. The Norton Rixson H28 (NOR-SC-H28S-105-587) is likewise heavy duty Grade 1 but is specified for offset-hung doors. Choose by how the door is hung; for a center-hung aluminum storefront leaf the BTS75VA in the barrier-free configuration is the direct answer.
