Ives 7255J SET US26D – Frequently Asked Questions

1) Does the Ives 7255J come as a complete top and bottom pivot, or are the pieces sold separately?
Both. Order the 7255JS and you get the top and bottom bases together as a set. The 7255JT is the top base on its own, which is the header mount, and the 7255JB is the bottom base on its own, which is the jamb mount. Each of the three is offered across the same finish range, so a worn bottom pivot can be replaced on its own and still match the top. Satin Chrome 626, for example, is stocked as a bottom base, as a top base, and as a full set.
2) Does the bottom pivot on the Ives 7255J mount into the floor or into the frame?
Into the jamb. The 7255J bottom pivot is a jamb mount and the top is a header mount, so the prep is marking, drilling and routing at the header and jamb surfaces from the Ives template rather than working the floor. That matters on a finished slab or an existing terrazzo entry. The Hager hospital pivot sets in our range work the other way and are chosen by floor type instead: the 510 Camtrol for wood floors, the 511 mortise set for masonry floors, and the 512 surface set for masonry applications.
3) I need pivots for an aluminum storefront door. Is the Ives 7255J the right set?
Probably not. The 7255J is a center hung set for standard doors at 1-3/4 inch minimum thickness, hung on the centerline of the opening. Aluminum storefront and glass entrance doors are normally carried on offset pivots cut to the door manufacturer's own prep, and those are keyed to the door line. ZenSupply carries the Kaba Ilco IL-OP-12 Series for Armalite and Trulite style doors, the IL-OP-13 Series 1/8 inch recessed set for YKK style doors and aluminum doors and frames, the IL-OP-14 Series for US Aluminum and Arcadia, and the IL-OP-15 Series for Pittco and Efco. Identify the storefront line first, then pick the matching series.
4) Can the Ives 7255J center hung pivot set be used on an aluminum storefront entrance door?
No. The 7255J is a center hung set for standard doors of 1-3/4 inch minimum thickness, with a header mount top pivot and a jamb mount bottom pivot. Aluminum entrance doors take offset pivots matched to the door system, and the Kaba Ilco IL-OP series is split that way: the IL-OP-12 Series for Armalite and Trulite style doors, the IL-OP-13 Series 1/8 inch recessed pivot set for aluminum doors and frames in YKK style, the IL-OP-14 Series for US Aluminum and Arcadia style doors, and the IL-OP-15 Series for Pittco and Efco style doors. All four are listed standard duty. Identify the door manufacturer first, because the offset pivot follows the door system rather than the opening size.
5) What center hung pivot suits a 1-3/8 inch thick door?
The Ives 7255J is recommended for doors of 1-3/4 inch minimum thickness, so a 1-3/8 inch leaf sits under what it is built for. The Hager 500 full mortise center hung pivot lists a door thickness range of 1-3/8 inch to 1-3/4 inch and is a rack and pinion pivot in standard weight brass construction, listed standard duty and without a fire rating. Weigh the door before you order it, since the 500 is a standard duty pivot while the 7255J covers heavy duty doors up to 500 lbs.
6) Which center hung pivot carries a fire rating for a 20 minute rated opening?
The Ives 7255J is UL 10C tested and approved for a 20 minute fire rating, certified to ANSI/BHMA A156.4 Grade 1, and carries the ANSI/BHMA A156.4 C07032 designation. Among the comparable center hung pivots, the Dorma CP440, the Dorma 8062 walking beam top pivot and the Hager 500 full mortise pivot are all listed without a fire rating, which puts them on unrated openings. If the drawing calls the opening out as a 20 minute rated door, the 7255J is the set in this group that answers to it.
7) How much height and floor clearance adjustment do the Ives 7255J pivots allow at install?
3/16 inch of vertical adjustment, positive locking, plus floor to door clearance adjustable anywhere from 3/16 inch to 3/4 inch. The clearance range is the number to check against the finish floor: 3/4 inch at the top end clears carpet or a tiled threshold, and 3/16 inch takes the leaf down tight to a bare slab. The vertical adjustment is for levelling the door and balancing the load once it is hung, not for making up a badly cut frame.
8) Do I need to specify left hand or right hand when ordering the Ives 7255J pivot set?
No handing to call out. The 7255J is non-handed, so the same part covers a left hand and a right hand opening. If you are stocking spares across a building, that means one top base and one bottom base on the shelf in your finish rather than a handed pair of each.
9) Is the Ives 7255J pivot set heavy duty enough for a high traffic main entrance?
It is certified to ANSI/BHMA A156.4 under product code C07032 at Grade 1, the highest grade in that standard and the one institutional specs normally call for on an entrance. Duty level is heavy duty, the substrate is brass, and the load ceiling is 500 pounds. On a busy entry the two things to confirm are that the leaf is under 500 pounds and that it is no bigger than 4'0" x 8'0", which is the size Ives caps the 7255J at.
10) Which center hung pivot sets are double acting for a door that has to swing both directions?
The Dorma CP440 is a double acting center hung pivot set for wood or steel doors up to 440 lb, listed standard duty with no fire rating. Hager's Camtrol hospital pivots are the other double acting route: the 510 for wood floors and the 512 as a surface mount for masonry floor applications, both listed heavy duty and without a fire rating. The Ives 7255J is a non-handed center hung set for doors up to 500 lbs with a 20 minute fire rating and a jamb mount bottom pivot. Confirm the swing called for on the door schedule before you pick between them, since a double acting opening and a rated opening pull toward different sets here.
11) The bottom pivot cannot be set into the concrete floor on this job. What are the alternatives?
The Ives 7255J bottom pivot is a jamb mount, so the bottom half anchors to the frame rather than being cut into the slab, and the top is a header mount pivot. Where the floor is the anchor point instead, the Hager hospital pivot sets are built for it: the 511 is a mortise set for masonry floor installation, the 512 is a Camtrol double acting surface set for masonry floor applications, and the 510 is a Camtrol double acting set for wood floors. All three are listed heavy duty. The deciding question is what the floor is and whether you are permitted to cut it.
12) Only the top pivot needs replacing. Can a top pivot be bought on its own, or is there a cross brand top pivot that fits?
The 7255J top base, the header mount half, is sold on its own in the same finishes as the set, including 626 satin chrome, 613 satin bronze oil-rubbed and 622 matte black, alongside the bottom base and the matched top and bottom set. For a cross brand top pivot on its own, the Dorma 8062 is a complete walking beam center hung top pivot with cover plate, listed heavy duty and without a fire rating. Match whichever you choose to the bottom pivot already in the opening and to the existing header prep, since a center hung top pivot has to work with the bottom half it is paired to.
13) Can I get the Ives 7255J center hung pivots in a finish that matches the rest of the hardware in the building?
Thirteen finishes, and each one is available as the top base, the bottom base, or the complete set: 605 Bright Brass, 606 Satin Brass, 612 Satin Bronze, 613 Satin Bronze Oil-Rubbed, 619 Satin Nickel, 622 Matte Black, 625 Bright Chrome, 626 Satin Chrome, 643E Aged Bronze, 689 Aluminum Painted, 691 Bronze Painted, 695 Dark Bronze and 706 Brass Painted. The three painted finishes, 689, 691 and 706, are the ones to look at when you are matching a painted frame rather than plated door hardware.
