Dorma 7471K Side Load Floor Pivot Set, Recommended Or Wood Doors Or Any Door Weighing In Excess Of 200 Pounds, Satin Chrome

Fire rated, with a 3 hour rating on the 7471K pivot set. That covers openings requiring up to a 3 hour assembly, such as stairwell and corridor separations. Among the offset pivot alternatives, the Ives 7215F and Ives 7215 are also fire rated, while the Hager 253 and Hager 497 pivots are not, so those two are off the table for a rated opening.

Offset. The 7471K mounts the pivot point off the door centerline so the door swings clear of the frame, which is what you want on a standard single-acting opening. If you need a door that swings both directions from a centered axis, an offset set like this is the wrong geometry and you want a center hung arrangement instead.

Two different fixes. Converting to a floor pivot set like the 7471K moves the door's weight onto the floor and the header, which is the durable answer for a leaf running to 440 lbs, but it means new floor and header prep. If the door and frame are otherwise sound and you just want to stop the hinge side pulling out, the Hager 253 full surface reinforcing pivot works with 4-1/2 inch wide hinges on 1-3/4 inch doors and bolts through without changing the hanging method. The Hager 253 is not fire rated, so on a rated opening the pivot set is the route.

Yes. The Ives 7212 heavy duty brass offset pivot set with top header mount is rated at 200 lb capacity and is fire rated, and the Ives 7212V is the same 200 lb fire rated brass offset set with a jamb mount instead of a header mount. The Dorma 7471K is built for wood doors and any door in excess of 200 pounds, carrying up to 440 lbs. For a door that never reaches 200 lb, the 7212 or 7212V sits in the right capacity band; pick between them on whether the frame gives you header or jamb to mount to.

No. The Kaba Ilco IP-10 and IP-12 series are intermediate pivots for aluminum doors and frames, and they are standard duty and not fire rated; the IP-12 is non handed. An intermediate pivot carries load between the top and bottom points and does not do the job of a floor pivot set. The Dorma 7471K is a heavy duty side load floor pivot set for wood doors and any door over 200 pounds, rated up to 440 lbs with a 3 hour fire rating. If the opening is a fire rated wood door, an intermediate aluminum pivot is not a substitute for it; the IP-22 series is likewise an intermediate pivot for aluminum doors and frames.

All three are heavy duty offset pivot sets, but capacity separates them. The 7471K carries up to 440 lbs. The Ives 7212, in both the top header mount and jamb mount versions, is a 200 lb set, and the Ives 7215 goes to 500 lbs with a header mount. If you're replacing an Ives 7212 on a door that has grown heavier, the 7471K is a step up in capacity; the 7215 and the stainless 7215F sit above it.

Order it as Dorma 7471K plus the finish number. The satin chrome version is the 7471K 626. The other three are 605 bright brass, 613 dark bronze oil-rubbed and 625 satin chrome. Give the brand as Dormakaba, since Dorma is the legacy name on the part.

For aluminum doors and frames the Kaba Ilco intermediate pivot series are the ones written for that opening: the IP-10 series, the IP-12 series which is non handed, and the IP-22 series, all standard duty. The Kaba Ilco IL-OP-10 series is a 1/8 inch recessed Arch/Vistawall pivot set, also standard duty, for those specific storefront systems. The Dorma 7471K is a heavy duty side load floor pivot set for standard commercial doors, recommended for wood doors and any door in excess of 200 pounds, which is a different opening than a light aluminum storefront leaf.

They do different jobs. The Hager 253 is a full surface reinforcing pivot for 4-1/2 inch wide hinges in a zinc plated finish, heavy duty, for 1-3/4 inch doors, and it is not fire rated. It reinforces a hinged door at the top; it does not hang the door on a pivot axis. The Dorma 7471K is a side load floor pivot set that carries the leaf itself, heavy duty, up to 440 lbs, with a 3 hour fire rating. On a hinged 1-3/4 inch door being reinforced against sag or abuse the 253 is the part; on a pivot hung opening it is not.

The Hager 497 is a heavy duty bottom pivot hinge with a ball bearing, forged bronze, full mortise, and it is not fire rated. It is the bottom point on its own, mortised into the door. The Dorma 7471K is a complete side load floor pivot set, heavy duty, offset mounting, for wood doors and any door in excess of 200 pounds up to 440 lbs, and it carries a 3 hour fire rating. If the job needs a single forged bronze bottom pivot for a full mortise prep, the 497 is that piece; if the opening is fire rated or needs the matched set, the 7471K is the one that answers it.

Four finishes on the 7471K: 605 bright brass, 613 dark bronze oil-rubbed, 625 satin chrome, and 626 satin chrome. 626 is the common commercial spec and the one to pick if you're matching satin chrome closers and exit hardware already on the building. 625 is the brighter of the two chrome numbers.

No wiring. The 7471K is a purely mechanical pivot set with no electronic components, so there's nothing to run to it and nothing that drops out in a power failure. Door position monitoring or an electrified transfer has to come from separate hardware.

No single set covers both. The Dorma 7471K is a heavy duty commercial floor pivot set for standard doors, recommended for wood doors and anything over 200 pounds, up to 440 lbs, and fire rated for 3 hours. The aluminum door and frame openings are served by the Kaba Ilco intermediate pivot series - IP-10, IP-12 which is non handed, and IP-22 - all standard duty. Standardizing usually means the 7471K on the heavy wood and rated leaves and the Kaba Ilco IP series on the aluminum entrances, with the Ives 7212 or 7215 offset sets covering the rated openings that fall at 200 lb or 500 lb.
