Norton Rixson H345 626 – Frequently Asked Questions

1) Will the Norton Rixson H345 top pivot work on a door taller than 8 feet 6 inches?
That is exactly what the H345 is built for. It's a center hung top pivot for doors over 8'6" (2491mm), where a standard-length pin doesn't give enough engagement into the top rail. The long throw pin drops 1-3/4" (44mm) into the top of the door, which is also what lets it stay engaged in buildings that settle noticeably over time.
2) Can I use the H345 top pivot with the floor closer I already have?
It pairs with any center hung bottom pivot or floor closer as long as that unit's pivot point sits 2" (50mm) or more from the door edge. Measure the offset on the closer or bottom pivot first; anything closer to the edge than 2 inches is outside what the H345 is stated to work with.
3) Do I need to order a left hand or right hand version of the Rixson H345 pivot?
No handing to specify. The H345 is non-handed, so the same top pivot serves both left and right hand openings. For a property manager stocking spares across a building, that means one part number covers every center hung door in the fleet.
4) Can the H345 center hung pivot be used on a fire rated door opening?
No. The H345 carries no fire rating, so it should not be specified on a labeled fire door assembly. For a rated opening you need pivot hardware carrying its own listing for that use.
5) Is the H345 a complete pivot set, or do I need to buy the bottom pivot separately?
The H345 is the top pivot only. To hang the door you also need the bottom half of the arrangement, either a center hung bottom pivot or a floor closer, and its pivot point has to be 2" (50mm) or more back from the door edge to work with this top pivot. Budget the floor closer or bottom pivot, and its cement case if the floor is being cut, as separate line items.
6) What is the difference between a center hung pivot like the H345 and a butt hinge or offset pivot setup?
A center hung arrangement puts the pivot point inside the door, roughly on the centerline, so the door swings about an axis under itself instead of hanging off the frame edge. The H345 is the top half of that arrangement and mounts fully concealed, hidden when the door is closed, which is why it gets specified on architectural entrances where nobody wants visible hinges. It also needs a matching center hung bottom pivot or floor closer below it. Butt hinges and offset pivots hang the door off the jamb line instead and swing one way from the edge, which is the simpler and cheaper route when appearance isn't driving the job.
7) Is the Rixson H345 pivot heavy enough for a high traffic commercial entrance?
It's rated heavy duty for commercial use. The load is carried on a walking beam type design with a 1/2" (13mm) diameter pivot pin turning in an oil-impregnated sintered bronze bushing, which is the construction used where a tall, heavy door cycles all day. Not a residential-grade part.
8) Our building has settled and the tall entry door is binding at the top. Will the H345 help?
That's one of the two conditions it's made for. The long throw pin engages 1-3/4" (44mm) into the top of the door rather than the shallower bite a standard pin takes, so the pivot stays properly engaged where a building has settled dramatically. It won't correct a frame that has racked out of square on its own, but it keeps the top of the door held and turning through that movement.
9) What finishes does the Norton Rixson H345 top pivot come in?
Ten finishes, so it can be matched to the rest of the trim on the opening: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome and 626 satin chrome. Worth noting that a center hung top pivot is concealed when the door is shut, so the finish shows only when the door swings open.
10) Does the Rixson H345 pivot need power or wiring at the head?
No power. The H345 is a purely mechanical top pivot with no electrified option, so there's no transfer, no raceway and no low voltage run to coordinate at the head of the frame.
