Dormakaba BTS75VD-90-74010-RH-626 – Frequently Asked Questions

1) Do I have to order the Dorma BTS75VD floor closer by hand?
Yes. Unlike the closer body in some floor closer lines, the BTS75VD is ordered left hand or right hand, so you need to know which way the door swings from the secure side before you place the order. Get it wrong and the unit will not drop into your prep correctly.
2) What do I have to specify when ordering a BTS75VD floor closer?
Four things: handing (left or right), finish for the cover plate, hold open (90 degree or 105 degree), and the spring/valve configuration, which comes either as size 1-4 with no backcheck or size 1-4 with no delay. If you want the 105 degree hold open, note it cannot be combined with the BF spring option.
3) Can a floor closer be installed in a thin concrete slab?
That's one of the reasons to pick the BTS75V. Its compact body allows installation in thin slab concrete subfloor construction where a larger cement case would not fit, and it can go in where a bigger closer would be prohibited by the depth available.
4) What's the difference between the Dorma BTS75VD and the Norton Rixson 3/4 inch offset floor closers?
All three are 3/4 inch offset floor closers, so they address the same hung condition. The Rixson 127 Series is a heavy duty 3/4 inch offset closer aimed at deep reveal applications, where the frame reveal pushes the pivot point further off the jamb. The Rixson 20 Series is a standard duty 3/4 inch offset closer with 180 degree door swing capability. The BTS75VD is heavy duty and Grade 1 with field-adjustable spring size 1-4, so it's the one to pick when you want to tune spring power after the door is hung.
5) What is the closest cross-brand equivalent to the Dorma BTS75VD floor closer for a 3/4 inch offset hung door?
The Norton Rixson 127 Series is the nearest match in another brand: it is a heavy duty 3/4 inch offset floor closer, the same hung condition the BTS75VD is built for. The BTS75VD is a Grade 1, heavy duty floor closer with offset mounting and an adjustable spring size 1-4, non-handed for single and double acting doors. The Rixson 127 is described for deep reveal applications, so confirm the reveal depth at your opening before treating the two as interchangeable.
6) Does the Dorma BTS75V have backcheck?
The series includes mechanical backcheck to catch the door before it slams into a wall on a windy opening. But read the configuration you are ordering: one of the two build options is size 1-4 with no backcheck, and the other is size 1-4 with no delay. Pick based on whether you need the backcheck or the delayed action more.
7) Can I use a floor closer on a double-acting door that swings both ways?
The BTS75V body is non-handed for single and double-acting doors, which is why floor closers are the usual answer on a door that swings in both directions. An overhead closer cannot do that on most applications, so for two-way traffic doors the floor closer is the right type.
8) Is the BTS75V heavy enough for a high-traffic commercial entrance?
It's a heavy duty, commercial-rated closer and the door closer is ANSI/BHMA Grade 1 certified, which is the top grade for cycle and durability testing. That's the specification most institutional and MRO buyers write for main entrances and other high-traffic openings.
9) Will the BTS75V work with my floor covering and threshold height?
A wide selection of interchangeable spindles is offered for the BTS75V, which is how the closer is matched to your finished floor covering and threshold condition. Measure from the closer body to the underside of the door after the floor finish is down, then select the spindle length to suit.
10) I need a cement case for a floor closer install, is that included?
A floor closer body and its cement case are separate line items. If you need the case for a new pour, the Norton Rixson 25 Series floor closer cement case is a heavy-duty galvanized steel case sold as its own package. Plan the case into the slab before the concrete goes down, because retrofitting one afterward means breaking floor.
11) Should I pick the 90 degree or 105 degree hold open on the BTS75V?
Pick by what the door can physically reach. The 90 degree hold open stops the leaf square to the frame, which is what you want when a wall, a return, or adjacent glass is close by. The 105 degree gives you more clear opening for carts and deliveries, but it cannot be ordered with the BF spring option. If barrier-free spring power matters more than the extra swing, take the 90.
12) If I need a floor closer for an offset hung door but the opening is lighter traffic, is there a standard duty option instead of the Dorma BTS75VD?
Yes. The Norton Rixson 20 Series is a standard duty 3/4 inch offset hung floor closer rated for 180 degree door swing, where the Dorma BTS75VD is a heavy duty, Grade 1 commercial closer. Both address the same 3/4 inch offset hung condition, so the decision comes down to the traffic level and swing you need at the opening.
13) For a barrier-free opening, does the Dorma BTS75VD or a Norton Rixson floor closer make more sense?
The Dorma BTS75VD carries an ADA Compliant value of No, though its spring power is adjustable from size 1 through 4 to suit both barrier-free and non-barrier-free openings. Note that the 105 degree hold open option is incompatible with the BF spring option. Among the alternatives, the Norton Rixson H28 Series is a Grade 1 heavy duty concealed floor closer for offset hung doors if you want a second option to evaluate against your accessibility spec.
14) Which offset floor closer should I choose if the opening needs to swing a full 180 degrees?
The Norton Rixson 20 Series is the one that states 180 degree door swing capability for 3/4 inch offset hung doors. The Dorma BTS75VD is specified with 90 degree or 105 degree hold open positions and is non-handed for single and double acting doors, so match the hold open point and swing requirement at the opening to the closer before ordering.
15) What finishes does the Dorma BTS75VD cover plate come in?
Nine BHMA finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed bronze, 618 bright nickel, 619 satin nickel, 625 bright chrome, and 626 satin chrome. If you are standardizing a lobby or a run of entrances, 626 satin chrome and 613 oil rubbed bronze are the two that most commonly match existing pivot and threshold hardware.
16) I need the closer to match finishes on the rest of the door hardware. How does the Dorma BTS75VD compare on finish options to the Rixson offset floor closers?
The Dorma BTS75VD is offered across nine BHMA finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed bronze, 618 bright nickel, 619 satin nickel, 625 bright chrome and 626 satin chrome, in left hand and right hand. If your spec is driven by finish matching on an offset hung opening, that range is the practical reason to specify the BTS75VD over a heavy duty alternative such as the Norton Rixson 127 Series 3/4 inch offset closer.
