Norton Rixson 320 626 – Frequently Asked Questions

1) Will the Norton Rixson 320 top pivot hold a 200 lb door?
No. The Model 320 is a light-duty center hung top pivot rated for doors up to 150 lbs. Past that weight you need a heavier center hung top pivot, not this one. Weight is the first thing to settle on a pivot, because an overloaded top pivot wears the bushing and the door starts to drop and drag.
2) Does the Norton Rixson 320 pivot work with the 127-3/4, 128-3/4, or 176 pivot sets?
Yes. The Model 320 is the standard top pivot for the Norton Rixson 127-3/4, 128-3/4 and 176 pivot sets, so it pairs directly with those bottom pivots and intermediate components without adapting anything.
3) Can I use the Rixson 320 center hung pivot on a fire rated door?
No. The Model 320 is a light-duty, non-fire-rated center hung top pivot. For a fire door opening you need pivot hardware carrying a fire rating, so specify a fire rated center hung pivot instead of the 320.
4) What size pivot pin does the Rixson 320 top pivot use and how deep does it engage?
The pin is 1/2 inch (13mm) diameter with 3/4 inch (19mm) engagement depth into the door's top pivot prep. Those two numbers decide whether it drops into an existing prep: if the door is already routed for a 1/2 inch pin at 3/4 inch depth, the 320 seats without re-machining. Longer than standard pins are offered in 1/4 inch (6mm), 1/2 inch (13mm) and 3/4 inch (19mm) increments when the frame condition needs extra reach.
5) Is the Rixson 320 top pivot a complete pivot set or do I need a bottom pivot too?
It is the top half only. The 320 is a top pivot in a top and bottom pivot arrangement, so the opening also needs the matching bottom pivot, typically from the 127-3/4, 128-3/4 or 176 set. Order both halves or the door has nothing to stand on.
6) Do I need to order a left hand and right hand version of the Rixson 320 top pivot?
One part covers both. The 320 top pivot is non-handed, so the same piece goes on a left hand or right hand opening. For a property manager or MRO buyer stocking spares across a building, that means one line item instead of two.
7) Center hung or offset pivot, which one do I need for a concealed look?
Center hung is what hides the hardware. The 320 mounts center hung and stays fully concealed with the door closed, which is why it gets specified on architectural interior openings where nothing should show on the face. The tradeoff is that a center hung door swings on an axis inside the opening, so it pivots both ways and does not sit tight to the frame face the way an offset-hung door does. If you need the door to swing one direction and clear the frame, an offset pivot is the right family, not this one.
8) Is the Rixson 320 pivot an electrified or power transfer pivot?
No, it is purely mechanical. The Model 320 carries no electrical option, so if the opening needs power to an electrified lock or exit device, the transfer has to come from a separate electric power transfer device or hinge, not from this pivot.
9) Is the Rixson 320 rated for a high traffic entrance door?
It is a light-duty commercial pivot for standard doors up to 150 lbs. That suits interior office, retail, school and healthcare openings. A heavy exterior entrance, a storefront door, or an opening taking constant traffic and closer forces calls for a heavy-duty center hung pivot instead, since the 320's duty level and weight ceiling are the limits you are working against.
10) How is the Rixson 320 top pivot mounted, and does the door need to be machined?
Yes, the door and frame both get prepped. The 320 is a concealed walking beam type top pivot, so the frame head and the door top rail are drilled and routed to the manufacturer's template, then the pivot is fastened with the wood and machine screws supplied. Installing it into an unprepped door is not a surface-mount job. If you are retrofitting, confirm the existing top prep matches the 1/2 inch pin before ordering.
11) What finishes does the Norton Rixson 320 top pivot come in?
Ten BHMA finishes: 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. Since the 320 is concealed when the door is closed, the finish matters mainly for matching the rest of the opening's hardware on a spec or a building standard.
12) Does the Rixson 320 pivot need greasing after it is installed?
No routine lubrication. The 320 runs on an oil-impregnated sintered bronze bushing, which carries its own lubricant, and the body is steel. On a maintenance rotation that means the top pivot is not a scheduled service item the way a mechanism needing periodic grease would be.
