Dormakaba BTS75VF-NHO-74010-RH-626 – Frequently Asked Questions

1) Do I have to order the Dorma BTS75VF floor closer handed?
Yes, handing is an order choice here. The BTS75VF is offered left hand and right hand, so determine the swing from the outside of the opening before ordering. The BTS75V closer body itself is non-handed and suits single and double acting doors, but the package you order is specified by hand.
2) Is the Dorma BTS75VF strong enough for a heavy exterior entrance door?
It is a heavy duty, ANSI/BHMA Grade 1 certified floor closer, with adjustable spring power size 1 through 4 so you can dial the closing force up for a wide or heavy leaf. Mechanical backcheck is built in, which protects the door and frame when it gets thrown open in wind. It is a commercial-rated unit, not a residential one.
3) What else could I use instead of the Dorma BTS75VF for a 3/4 inch offset hung door?
Norton Rixson makes direct alternatives in the same 3/4 inch offset arrangement. The Rixson 127 Series is a heavy duty 3/4 inch offset floor closer intended for deep reveal applications, and the Rixson 20 Series is a 3/4 inch offset hung floor closer rated standard duty with 180 degree door swing capability. The Norton Rixson H28 Series is another heavy duty concealed floor closer for offset-hung doors carrying a Grade 1 rating, which is the closest match to the BTS75VF on duty and grade.
4) Does the Dorma BTS75VF hold the door open?
No. The BTS75VF is the non-hold open version, so the door closes from any position. If you need the leaf to stand open at a set angle, you need a hold open variant of the BTS75V rather than the F.
5) Can a floor closer like the BTS75V go into a thin concrete slab?
Yes, that is one of the reasons to pick this one. The BTS75V body is compact enough for installations where a larger floor closer will not fit, including thin slab concrete subfloor construction. It also takes a wide selection of interchangeable spindles so it can be matched to the floor covering or threshold thickness you are working over.
6) Why choose a floor concealed closer over an overhead closer on a glass or aluminum entrance?
A floor concealed closer like the BTS75V puts the whole mechanism under the floor, so nothing shows on the door or the header. That is the usual answer on all-glass and narrow-top-rail entrances where there is no room or no appetite for an overhead unit, and where the head detail cannot carry a closer. The tradeoff is that the floor has to be prepped, so it is far easier on new construction or a slab you are already opening up than on a finished floor.
7) Which floor closer should I use if the door has a deep reveal?
The Norton Rixson 127 Series is a heavy duty 3/4 inch offset floor closer built for deep reveal applications. The Dorma BTS75VF is a heavy duty Grade 1 offset hung closer with adjustable spring size 1 to 4 and mechanical backcheck, and its compact body suits thin slab concrete subfloor construction. Pick based on the reveal condition and the slab depth at the opening.
8) Does the Dorma BTS75VF work on a double acting door, or do I need a different closer?
The BTS75V Series body is non-handed and suits single and double-acting doors, though the BTS75VF is configured single acting and non-hold open. Among offset hung alternates, the Norton Rixson 20 Series is a 3/4 inch offset hung closer rated for 180 degree door swing. Verify the swing and hold open requirement for the opening before ordering.
9) What finish does the Dorma BTS75VF floor closer come in?
Satin chrome, 626, on all versions. That is the standard commercial cover plate finish and it will sit alongside 626 pulls, locks and pivots without a mismatch, which matters when you are standardizing hardware across a building.
