Dormakaba 75240 RH AL – Frequently Asked Questions

1) Will the Dormakaba 75240 pivot work on a left-hand door?
No. The 75240 RH AL is factory-configured right-handed, so it only suits a right-hand offset hung door. Handing on an offset pivot is not field-reversible, so a left-hand opening needs the left-hand version of the pivot instead. Determine handing from the outside of the door: if it swings away from you with hinges on the right, it is right-handed.
2) Does this pivot suit a center hung door or an offset hung door?
Offset hung only, with a 3/4 inch offset. Center hung doors pivot on the door's centerline and take a different pivot set entirely, so the 75240 will not substitute there. Check the existing top pivot and floor closer arrangement before ordering.
3) Is the 75240 a complete pivot set or just one piece?
It is the intermediate pivot alone, sold as a Dormakaba replacement part. A full offset hung installation also needs the top pivot and the bottom pivot or floor closer, so order those separately if you are building an opening rather than replacing a worn intermediate.
4) What is the difference between the Dormakaba 75240 intermediate pivot and the Adams Rite B1923 reinforcing pivot?
Both share a 3/4 inch offset, but they do different jobs. The Dormakaba 75240 is a full mortise intermediate pivot for right-handed, 3/4 inch offset hung installations on 1-3/4 inch lead lined doors, serving as the intermediate pivot point in a multi-pivot door system. The Adams Rite B1923 is a reinforcing pivot with 3/4 inch offset intended for use with 4-1/2 inch wide butt hinges, so it supplements a butt-hung door rather than acting as part of an offset pivot set. If the door is hung on butt hinges and you want added support at the hinge, the B1923 matches that arrangement; if the opening uses offset pivots, the 75240 is the corresponding part.
5) For a lead lined door in a radiology suite, which pivot is specified?
The Dormakaba 75240 is the one of these built specifically for lead lined construction: it is a full mortise intermediate pivot for 1-3/4 inch lead lined doors in 3/4 inch offset hung applications, which is why it turns up in medical and radiological work. The Adams Rite B1921 and B1923 are reinforcing pivots specified by butt hinge width, 4 inch and 4-1/2 inch respectively, without a lead lined door designation. Note the 75240 is handed, so confirm the leaf is right-handed before ordering.
6) Why does a lead lined door need a specific intermediate pivot?
Lead lined doors run substantially heavier than a standard hollow metal or wood leaf, and the 75240 is made for that duty as the intermediate pivot in a multi-pivot set, taking part of the load off the top and bottom pivots. That is what makes it common in radiology suites, hospital treatment rooms, and other shielded openings.
7) Is the 75240 a full mortise pivot or a surface applied one?
Full mortise. The pivot body recesses into prepped pockets in the door edge and frame rather than screwing onto the face, so the door and frame need the correct mortise prep. On a replacement where the original Dormakaba pivot was mortised, that prep is already there.
8) Is the Adams Rite B1921 a drop-in replacement for a Dormakaba 75240 pivot?
No. The Adams Rite B1921 is a reinforcing pivot with a 1/2 inch offset sized for 4 inch wide butt hinges, while the Dormakaba 75240 is a full mortise intermediate pivot with a 3/4 inch offset for offset hung doors. The offset dimension and the hanging method both differ, so the two are not interchangeable in the same prep. Within the Adams Rite pair, the B1923 is the 3/4 inch offset version, for 4-1/2 inch wide butt hinges.
9) What finish does the Dormakaba 75240 RH come in?
Aluminum painted, listed as finish 689. Since most of the pivot is concealed in the mortise, only the exposed leaf edge shows, and 689 blends with clear anodized aluminum frames and the painted aluminum trim common on institutional openings.
10) Is this pivot rated for commercial traffic or is it a residential part?
Commercial. The 75240 is catalogued as commercial-grade Dormakaba pivot hardware and is used in healthcare, government, education, and multi-tenant commercial buildings, which is why it shows up in specialty lead lined openings rather than residential work.
