Dormakaba BTS75VD RH 626 – Frequently Asked Questions

1) Does the Dorma BTS75VD floor closer need to be ordered left hand or right hand?
You do pick a hand when ordering the BTS75VD, left hand or right hand. The closer body itself is non-handed and works for single and double acting doors, so the hand you select is about how the unit is set up for your opening. Determine the swing from the outside of the door before you order.
2) Will a non-hold-open floor closer work if I want the door to stay open for deliveries?
No. The BTS75VD is the non-hold-open version, so the door returns to closed every cycle with no detent to park it open. If you need the leaf to stand open at a set point, specify a hold-open floor closer instead. Non-hold-open is what you want on any opening where the door has to self-close.
3) Can one BTS75V closer cover different door weights, or do I have to order a specific spring size?
One unit covers the range. Spring power on the BTS75VD is field adjustable from size 1 through size 4, so the same closer can be tuned down for a light barrier-free opening or up for a heavy entrance leaf. That also means you can stock a single model across a building with mixed door sizes.
4) Is a floor-concealed closer like the BTS75V rated for high traffic commercial entrances?
Yes. The BTS75VD is ANSI/BHMA Grade 1 certified and classified heavy duty for commercial use, which is the top grade for closers and the level specified for main entrances, schools and other high cycle openings. It also has mechanical backcheck to stop the door slamming into the wall on a windy opening.
5) What is a direct alternative to the Dorma BTS75VD floor closer for a 3/4 inch offset hung door?
The Norton Rixson 127 Series is a heavy duty 3/4 inch offset floor closer built for deep reveal applications, so it covers the same 3/4 inch offset hung geometry as the BTS75VD. The BTS75VD is ANSI/BHMA Grade 1 with adjustable spring power size 1 through 4 and a mechanical backcheck, and it is non-handed for single and double acting doors even though it is ordered left hand or right hand. Confirm the cement case and spindle length against the floor construction before committing either way.
6) What heavy duty Grade 1 floor closer competes with the Dorma BTS75VD on offset hung openings?
The Norton Rixson H28 Series is a heavy duty concealed floor closer for offset-hung doors carrying an ANSI/BHMA Grade 1 rating, the same duty level and grade as the BTS75VD. Both are floor concealed and both serve offset hung doors. The BTS75VD is ordered non-hold open with a field adjustable spring size of 1 to 4 and is non-handed for single and double acting doors, so match hold open requirement and spring range when choosing between them.
7) Will the BTS75V fit in a thin slab concrete floor?
That is one of the reasons to pick it. The BTS75V body is compact enough to install where a larger floor closer will not fit, including thin slab concrete subfloor construction. It also takes a range of interchangeable spindles so it can be matched to your floor covering thickness or threshold detail.
8) Do I need a cement case with a floor closer, and is one included?
A floor closer is set into a case cast into the slab, and the case is a separate item from the closer body. The BTS75VD is supplied as the closer, so plan the floor prep and case as part of the job. ZenSupply carries the Norton Rixson 25 Series floor closer cement case in galvanized steel if you are specifying a Rixson package.
9) Is there a lighter duty floor closer than the Dorma BTS75VD for an interior offset hung door?
The Norton Rixson 20 Series is a standard duty 3/4 inch offset hung floor closer with 180 degree door swing capability, which is the step down from the heavy duty BTS75VD. The BTS75VD is rated heavy duty and Grade 1 for commercial openings with adjustable spring power from size 1 to 4. If the opening sees light interior traffic and does not need that spring range, the 20 Series matches the same offset hung mounting.
10) Can I order the Norton Rixson 25 Series cement case instead of the Dorma BTS75VD?
No, those are different items. The Norton Rixson 253000 is a floor closer cement case in heavy-duty galvanized steel construction, meaning the box that is set into the floor slab, not the closer mechanism. The Dorma BTS75VD is the closer body itself, Grade 1, non-hold open, with adjustable spring size 1 to 4 and mechanical backcheck. A cement case from one manufacturer is not a substitute for a closer from another, and cases are matched to their own closer bodies.
11) For a deep reveal opening, should I use the Dorma BTS75VD or the Norton Rixson 127?
The Norton Rixson 127 Series is specifically a heavy duty 3/4 inch offset floor closer for deep reveal applications, so it is the one written for that condition. The Dorma BTS75VD is a 3/4 inch offset hung Grade 1 floor concealed closer whose selling point is a compact body that fits where a larger closer will not, including thin slab concrete subfloor construction, with a wide range of interchangeable spindles for different floor coverings and thresholds. Choose on reveal depth and available slab depth at the opening.
