Dormakaba 75523 626 – Frequently Asked Questions

1) Is the Dormakaba 75523 pocket pivot rated for a 3-hour fire door?
Yes. The 75523 pocket pivot carries a 3-hour fire rating, so it can go into a 3-hour fire rated door assembly without compromising the rating of the opening. That also covers lower-rated openings (90 minute, 60 minute), since a higher-rated component is acceptable on a lesser-rated assembly.
2) Is the Dormakaba 75523 a genuine OEM part or an aftermarket copy?
It is a genuine Dormakaba replacement component, sold under model number 75523 and part of the Dorma door closer parts and accessories range (Dorma is the former brand name for Dormakaba). For a fire rated opening that matters: substituting an unlisted aftermarket pivot is what gets an assembly written up on inspection.
3) What is the difference between the Dormakaba 75523 pocket pivot and the Adams Rite B1921 reinforcing pivot?
They solve different problems at the door edge. The Dormakaba 75523 is a pocket pivot with a 3-hour fire rating, sold as a replacement part for Dormakaba (formerly Dorma) door closer systems in commercial openings. The Adams Rite B1921 is a reinforcing pivot with a 1/2 inch offset intended for use with 4 inch wide butt hinges, so it supplements a hinged door rather than acting as the pocket pivot in a closer-equipped assembly. If you are restoring a Dormakaba closer installation, the 75523 is the matching component; if you are reinforcing a butt-hinged aluminum door, look at the B1921 family.
4) Which pivot should I specify on a 3-hour fire rated door assembly?
The Dormakaba 75523 pocket pivot is rated for 3-hour fire door assemblies and is the choice when the opening's fire rating has to be preserved, which is why it turns up in healthcare, education, and government work. The Adams Rite reinforcing pivots in the B1921 and B1923 series are described by hinge width and offset - 1/2 inch offset for 4 inch butt hinges and 3/4 inch offset for 4-1/2 inch butt hinges - and are selected on that geometry. For a fire-rated assembly served by a Dormakaba closer, the 75523 is the part that matches the rating requirement.
5) What finishes does the Dormakaba 75523 pocket pivot come in?
Six BHMA finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome and 626 satin chrome. If you are matching existing pivots or closer hardware on adjacent openings, 626 satin chrome and 613 oil rubbed bronze are the two that most often turn up on commercial doors.
6) What is a pocket pivot actually for, versus a standard butt hinge or a center hung pivot?
A pocket pivot swings the door clear of the frame opening so the door leaf sits out of the way when fully open, which is why it shows up on corridors and patient room doors where the full clear width is needed. A butt hinge leaves the leaf in the opening, and a center hung pivot puts the door axis inside the frame for a double-acting or balanced swing. The 75523 is the pocket pivot type, sold as a commercial replacement part for Dormakaba closer systems.
7) Can I replace a worn pocket pivot on a Dorma closer without changing the whole closer?
Yes, that is the point of the 75523. It is a field-replaceable component for Dormakaba and older Dorma door closer systems, so a worn or damaged pivot can be swapped to restore proper closing action instead of replacing the closer assembly. On a fire rated opening, use the 3-hour rated pivot so the assembly keeps its listing.
8) Can an Adams Rite reinforcing pivot be used as a substitute for the Dormakaba 75523?
It is not a like-for-like swap. The Adams Rite B1921 and B1923 are reinforcing pivots defined by their offset and the butt hinge width they pair with - 1/2 inch offset with 4 inch hinges and 3/4 inch offset with 4-1/2 inch hinges. The Dormakaba 75523 is a pocket pivot supplied as a genuine OEM replacement component for Dormakaba door closer systems and carries a 3-hour fire rating. If you are replacing a worn pocket pivot in an existing Dormakaba closer installation, stay with the 75523 so the closer geometry and the assembly's fire rating are both preserved.
9) If I need to match the existing brass or bronze hardware on my doors, which pivot gives me finish options?
The Dormakaba 75523 pocket pivot is offered in six finishes - 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, and 626 satin chrome - so it can be matched to brass, bronze, or chrome trim already on the openings. The Adams Rite B1921 and B1923 reinforcing pivots are identified by series and by the butt hinge width and offset they serve rather than by a finish range, so specify those by geometry and confirm the appearance separately.
10) Is the Dormakaba 75523 pivot suitable for residential use?
It is classed as commercial. The 75523 is meant for commercial door hardware duty (office buildings, schools, healthcare, retail, industrial, government, and multi-tenant residential corridors) rather than single-family residential openings.
