Dormakaba BTS80A-4-74010-626 – Frequently Asked Questions

1) Will the Dorma BTS80A floor closer handle a heavy aluminum entrance door?
The BTS80A is rated for doors up to 660 lbs and is classed heavy duty, which covers most aluminum storefront and glass entrance leaves. It is a floor-concealed closer, so the door weight is carried on the closer spindle in the floor rather than on the header, which is why it takes far more weight than a surface closer on the same opening.
2) Does the BTS80A work on a double acting door that swings both ways?
Yes. The BTS80A is a double acting closer and it is non-handed, so it serves single and double-acting doors and you do not order a left or right hand version. On a pair of double-acting leaves you need one closer per leaf.
3) Which closer size should I order for the Dorma BTS80A, 3, 4 or 6?
The BTS80A comes in spring size 3, 4 and 6, and the springs are fixed rather than adjustable, so the size is a ordering decision you cannot correct on site. Size follows door width and weight: the larger the leaf and the more wind or stack pressure on the opening, the higher the size. Size 6 is where you land on wide, heavy exterior aluminum entrances near the 660 lb capacity; 3 and 4 suit narrower interior or protected openings.
4) Can a floor closer be installed in a thin concrete slab?
That is one of the reasons to pick the BTS80 body. Its compact case is made for thin slab concrete subfloor construction where a larger cement case would not have the depth, and the same compactness lets it go into openings where a bigger closer is prohibited by the floor build-up.
5) Will the BTS80A work with my floor finish and threshold height?
Yes, through spindle selection. The BTS80 takes a wide range of interchangeable spindles so the closer can be set for the floor covering thickness and the threshold detail on your opening, whether that is bare concrete, tile, or a raised threshold. The spindle is the part that takes up the difference between the closer body in the floor and the underside of the door.
6) Is the Dorma BTS80A fire rated or ADA compliant?
No on both counts. The BTS80A is not fire rated and is not ADA compliant, so it is not the closer for a labeled fire door assembly or for an opening where you have to meet ADA opening force. It is a commercial-duty closer for standard aluminum and glass entrances. If the opening is fire rated, you need a labeled closer instead.
7) BTS80A or an offset-hung floor closer like the Rixson 127, which do I need?
It comes down to how the door is hung. The BTS80A is a center-hung double acting closer for aluminum door and frame, where the pivot line sits in the middle of the door and the leaf swings both directions. The Norton Rixson 127 Series is a 3/4 inch offset closer built for deep reveal applications, and the Norton Rixson H28 Series is for offset-hung doors, where the door hangs on an offset pivot at the jamb and swings one way. Measure the existing prep before you buy: an offset-hung opening will not take a center-hung closer without re-prepping the floor.
8) Which floor closers besides the Dorma BTS80A carry an ANSI/BHMA Grade 1 rating?
The BTS80A is ANSI/BHMA Grade 1 certified. Among comparable floor closers, the Norton Rixson H28 Series concealed floor closer is Grade 1, and the Norton Rixson 25 Series floor closer cement case is Grade 1 as well. For a facility standardizing on a Grade 1 floor closer across entrances, all three carry that certification.
9) What is a heavy duty alternative to the Dorma BTS80A floor closer for an offset-hung door?
The BTS80A is a double acting concealed floor closer for aluminum door and frame construction, rated heavy duty and controlling doors up to 660 pounds. When the opening is offset-hung rather than center-hung aluminum, the Norton Rixson H28 Series concealed floor closer is built for offset-hung doors and is also heavy duty and Grade 1. The pivot arrangement is the deciding factor: the door's hanging geometry has to match the closer that goes under it.
10) Is the Norton Rixson 25 Series cement case a substitute for a Dorma BTS80A closer?
No. The Norton Rixson 253000 is a floor closer cement case in heavy-duty galvanized steel construction, which is the buried housing the closer body sets into, not a closer mechanism. The BTS80A is the concealed floor closer itself, double acting and rated for doors up to 660 pounds, ordered by closer size 3, 4 or 6. A cement case is ordered alongside a floor closer, not in place of one.
11) Does the BTS80A hold the door open, and does it have backcheck?
Both. The BTS80A has a hold open feature and mechanical backcheck. The backcheck is what stops a heavy aluminum leaf being thrown into the adjacent wall or sidelite when someone pushes it hard or the wind catches it, which matters most on the sizes carrying the biggest doors.
12) What finishes does the Dorma BTS80A cover plate come in?
Five plated finishes plus black: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, and 693 black. Every one of those is offered in all three spring sizes, so matching the existing floor plates on the other entrance doors in a building does not restrict which size you order.
13) Can I standardize on the BTS80A across all the entrance doors in a building?
It is a reasonable fleet standard for aluminum entrances. The closer is non-handed, so you stock one closer per size rather than lefts and rights; three spring sizes cover narrow interior leaves through heavy exterior doors up to 660 lbs; and the six cover finishes let the visible plate match across openings. Keep in mind it is not fire rated, so any labeled opening in the building has to be handled separately.
14) I need a floor closer for a lighter interior door, not something as heavy as the Dorma BTS80A. What else is there?
The BTS80A is a heavy duty closer sized for doors up to 660 pounds. Where the door is lighter and hung on a 3/4 inch offset pivot, the Norton Rixson 20 Series floor closer is a standard duty unit with 180 degree door swing capability. It is the lighter-duty option in the floor closer family, so confirm the door leaf weight and the pivot arrangement before switching.
15) Which floor closers handle a double acting door if the Dorma BTS80A does not fit?
The BTS80A is non-handed for single and double-acting doors, with a compact body that suits thin slab concrete subfloor construction. If the floor depth or the hanging method rules it out, the Norton Rixson H28 Series is a heavy duty Grade 1 concealed floor closer for offset-hung doors, and the Norton Rixson 127 Series is a heavy duty 3/4 inch offset closer for deep reveal openings. Match the replacement to how the door is pivoted and to the depth available in the floor.
