Dormakaba 75120 3/4" Offset Hung Full Mortise Standard Top Pivot

The 75120 top pivot is rated for doors up to 440 lbs. That covers most solid core wood, hollow metal, and heavier entrance doors on a standard opening. It is a standard duty pivot, so if the leaf is heavier than 440 lbs you need to step up to a heavier capacity set rather than doubling up on this one.

Yes. The 75120 is fire rated with a 3 hour rating, so it can be used on openings up to a 3 hour label. That is the main reason to pick it over an unrated pivot on a stair, corridor, or shaft opening where the door assembly carries a label.

The 75120 is the top pivot only. It is a full mortise unit, meaning it mortises into the top rail of the door and the frame head rather than surface mounting. To hang the door you also need the matching bottom pivot from the same offset system, and on a taller or heavier leaf an intermediate pivot as well. Order the bottom half at the same time so the pair matches on offset and capacity.

Look at the Ives 7215 offset pivot set, rated at 500 lb capacity with a header mount and listed as heavy duty and fire rated, or the 7215F stainless steel 3/4 inch offset version with the same 500 lb rating. The Dormakaba 75120 is a standard duty top pivot rated to 440 lbs, so on a leaf above that the Ives 7215 family is the move. The lighter Ives 7212 sets are 200 lb capacity and would be a step down, not a step up.

The Ives 7215F is a stainless steel 3/4 inch offset pivot set with a top header mount, rated for 500 lb doors and fire rated. The Dormakaba 75120 is a 3/4 inch offset hung full mortise top pivot carrying doors up to 440 lbs, also fire rated, with a 3 hour fire rated time. Both share the 3/4 inch offset geometry, so the header prep concept is the same, but the Ives is sold as a set covering top and bottom while the Dormakaba 75120 is the top pivot for a top and bottom pivot arrangement. Confirm the door weight against the 440 lb figure before swapping.

The Hager 497 is a heavy duty bottom pivot hinge with a ball bearing, forged bronze, full mortise. The Dormakaba 75120 is the top pivot for a top and bottom offset hung set, also full mortise. They occupy different positions in the opening rather than competing, but the two are not a matched pair on fire performance: the 75120 is fire rated with a 3 hour rating and the Hager 497 is not fire rated. On a labeled opening, keep the top and bottom from a listed set.

Four finishes: 605 bright brass, 613 oil-rubbed satin bronze, 625 satin chrome, and 626 satin chrome. Those are standard BHMA finish numbers, so match the number on your existing closers, hinges, and exit hardware rather than matching by eye. On a full mortise top pivot most of the unit is buried in the door and frame anyway, so the finish only shows on the exposed plate.

The 75120 is a full mortise pivot for a standard commercial door, meaning it gets mortised into the door and frame. Aluminum storefront and curtainwall openings normally take a pivot made for that framing system, like the Kaba Ilco IL-OP-10 recessed Arch/Vistawall pivot set or the IP-10 series for aluminum doors and frames. If you are working a glass front or storefront entrance, start with those instead.

Offset hung pivots are single-swing by nature, so the top pivot mounts to one side of the opening and the door swings one way. Confirm the hand of the opening before you order and keep the top and bottom halves on the same hand. Handing is the most common reason a pivot comes back.

Yes, and that is a reasonable way to run it. The 75120 carries a 3 hour fire rating, so it is acceptable on rated stair and corridor openings and equally usable on non-rated doors, as long as each leaf is 440 lbs or under. One part number, one prep, one finish across the fleet. Just watch the heavy openings, where a 500 lb heavy duty set like the Ives 7215 is needed instead.

For lighter leaves, the Ives 7212 is a heavy duty brass offset pivot set with a top header mount rated at 200 lb capacity, and the Ives 7212V is the same 200 lb set with a jamb mount instead. Both are fire rated. The Dormakaba 75120 top pivot carries doors up to 440 lbs, so it is the choice when the leaf exceeds what a 200 lb set will hold. Match the mount style to your frame condition - header versus jamb is not interchangeable prep.

No. The Hager 253 is a full surface reinforcing pivot for 4-1/2 inch wide hinges in a zinc plated finish, sized for 1-3/4 inch doors - it reinforces a butt hinged door at the top, it does not hang a pivot hung door. The Dormakaba 75120 is the full mortise top pivot that carries an offset hung leaf up to 440 lbs. The Hager 253 is also not fire rated, while the 75120 carries a 3 hour fire rating. If the door swings on butt hinges, the 253 is the right family; if it swings on pivots, it is not a substitute.

No. The 75120 is a purely mechanical pivot with no electrical option. If you need to run power through the door for an electrified lock or exit device, you will need a separate electric power transfer or a door loop; the pivot will not carry it.

The Kaba Ilco IP-12 series intermediate pivots for aluminum doors and frames are listed as non handed, which lets one part number cover both swings on an intermediate point. They are standard duty and not fire rated, so they suit unlabeled aluminum entrances. The Dormakaba 75120 is a full mortise top pivot for a standard door, fire rated at 3 hours and good to 440 lbs, so a labeled opening stays with the top and bottom pivot arrangement rather than the aluminum intermediate line.
