Norton Rixson F280 626 – Frequently Asked Questions

1) Will the Norton Rixson F280 top pivot work on a fire rated door?
Yes. The F280 offset top pivot set carries a 3 hour fire rating, which is why it is built with ferrous material rather than a non-ferrous casting. Fire door assemblies require ferrous pivot hardware, so this is the version to specify when the opening is rated. It is a commercial duty part intended for standard doors.
2) What does the 3/4 inch offset on a Rixson F280 pivot actually measure?
The 3/4 inch (19mm) is measured from the centerline of the pivot to the face of the door. That dimension sets how far the door stands off the frame and where the leading edge swings, so it has to match the offset your closer, threshold and floor pivot were laid out for. Mixing a 3/4 inch offset top pivot with a bottom pivot cut for a different offset will bind the door.
3) Do I have to order the Rixson F280 pivot left hand or right hand?
Handing matters here. The F280 is a handed pivot, so you specify the hand when you order. Stand outside the door, on the side it swings away from: if the hinge edge is on your left it is left hand, on your right it is right hand. Get it wrong and the pivot will not line up with the door prep.
4) Can I use a half surface pivot when the door cannot be mortised?
That is exactly the case the F280 is made for. It is a half surface pivot, so the door portion mounts to the face of the door instead of being routed into it. Flush doors that cannot take a mortise, including many fire rated leaves, get hung this way. The tradeoff is a visible plate on the door face.
5) Does the Rixson F280 include the bottom pivot, or do I order that separately?
The F280 is the top pivot set for an offset hung opening. A complete offset hung door needs a matching bottom pivot or a floor closer with the same 3/4 inch offset, ordered alongside it. Confirm the bottom half is cut for 3/4 inch offset, because the two ends have to share the same offset for the door to swing free.
6) Why would I use an offset pivot instead of butt hinges on a commercial door?
Offset pivots hang the door on a single point at the head and floor instead of along the hinge edge, so the load goes down through the pivot rather than into the frame leg. That is what you want on heavy doors, on high traffic openings, and anywhere a floor closer is doing the closing. Butt hinges are the simpler choice on a light interior door with no closer. The F280 is the top half of an offset hung set, so it pairs with a matching bottom pivot or floor closer, not with hinges.
7) What if my door needs a longer pivot pin than standard?
Longer than standard pivot pins are available for the 280 Series in 1/4 inch (6mm), 1/2 inch (13mm) and 3/4 inch (19mm) increments. That is the fix when the head clearance or frame condition puts the door lower than the standard pin engagement allows. Call out the increment you need at the time of order, since it is not something you can add later on site.
8) Is the Norton Rixson F280 pivot an electrified or power transfer part?
No. The F280 is a mechanical pivot with no electrical function. If you need to run power through the top of the door for an electric strike, mag lock or electrified lockset, that takes a separate electric power transfer or an electrified pivot, not this one.
9) What finishes does the Norton Rixson F280 offset top pivot come in?
Seventeen finishes, so it can be matched to whatever else is on the opening: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil rubbed, 613E dark oxidized satin bronze, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 689 aluminum painted, 690 dark bronze, 691 bronze painted, 696 satin brass painted, BSP black suede powder and WSP white suede powder. For a property manager standardizing a building, 626 and 689 are the two that most commonly match existing commercial hardware.
10) What screws come with the Rixson F280 pivot, and can I get tamper resistant fasteners?
Torx screws are an option on the F280. On a fire rated or high traffic opening where you do not want the pivot backed off with a common driver, specify the Torx fasteners when ordering rather than assuming standard screws will do.
