Norton Rixson L180 Series Lead-Lined Heavy Duty Top Pivot with 3/4" Offset

The Norton Rixson L180 is a full-mortise top pivot for lead-lined commercial doors. The 3/4" (19mm) offset is measured from the centerline of the pivot to the face of the door. Mounting screw holes are spaced to straddle the lead lining at the center of the door, making this pivot the correct choice for radiology, nuclear medicine, and other radiation-shielded openings. Compatible with L147 and L117 intermediate pivots and L27 floor closers.

Norton Rixson L180RH-626 – Frequently Asked Questions

1) Will the Norton Rixson L180 top pivot work on a lead-lined door?
That's exactly what the L180 is built for. It's a full mortise top pivot whose mounting screw holes are spaced to straddle the lead lining at the center of the door, so the fasteners land in the door material rather than driving into the shielding. That's the difference between it and a standard 180 top pivot, and it's why it shows up in radiology, nuclear medicine, radiation therapy suites, shielded research labs, and lead-lined government openings.
2) What does the 3/4 inch offset on the L180 pivot mean for my door swing?
The 3/4 inch (19mm) figure is measured from the centerline of the pivot to the face of the door, so the door hangs offset from the jamb rather than pivoting on its own edge. It's an offset hung arrangement, and the door swings clear of the frame on that geometry. If your frame prep and floor closer were laid out for a different offset, the leaf won't line up, so the offset has to match across the top pivot, the intermediate pivot, and the closer.
3) Do I have to specify handing when ordering a Rixson L180 top pivot?
Yes, the L180 is a handed pivot. Left Hand and Right Hand are separate parts, not a field-reversible one, so you order to the swing of the opening. Every finish is offered in both hands: 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. Getting the hand wrong on a lead-lined opening means recutting a mortise pocket in a shielded door, which is not a cheap mistake.
4) What else do I need to order with the L180 top pivot to hang the door?
A top pivot is only one third of the set. The L180 pairs with an L147 or L117 intermediate pivot and an L27 floor closer to carry and control the leaf. The pivot itself ships with wood and machine screws; Torx screws are an option if your spec calls for them. Longer pivot pins are also available in 1/4, 1/2, or 3/4 inch increments when the head condition needs the extra length.
5) Can the Rixson L180 pivot go on a fire rated opening?
No. The L180 is not a fire rated pivot, so it should not be specified on a labeled opening. If the lead-lined door in question also carries a fire label, the pivot set has to be a rated one and this is the wrong part for it. On unlabeled shielded openings, which covers most imaging and therapy suites, it's the correct choice.
6) Should I use an offset pivot like the L180 or center hung hardware on a lead-lined door?
Offset hung is the choice when the door has to swing one direction and sit tight to a frame stop, which is the normal condition on a shielded room. The L180 hangs the leaf 3/4 inch off the door face and works with an L27 floor closer below. Center hung hardware puts the pivot point inside the door and lets it swing both ways, which is a different opening entirely. For radiology and nuclear medicine doors where the shielding has to close against a stop, offset hung with a matched top pivot, intermediate pivot, and floor closer is the arrangement to spec.
7) Is the Rixson L180 top pivot steel, and will it interfere near imaging equipment?
The base material is non-ferrous. That matters on the openings this pivot is made for, because radiology and nuclear medicine departments have ferrous material restrictions around imaging equipment. It's also a mechanical pivot with no electronic components, so there's nothing to wire and no power to run to the head of the frame.
8) Will the L180 pivot match the other pivoted doors in my facility?
If the rest of the openings are Rixson offset hung on 3/4 inch offset with L147 or L117 intermediate pivots and L27 floor closers, the L180 drops into the same standard. Finish is where matching usually breaks down, so the ten options cover the common ones: 605, 606, 611, 612, 613, 618, 619, 622, 625, and 626. Satin chrome 626 and satin brass 606 are the two most likely to be already on a healthcare or institutional opening.
9) Does the L180 need a frame stop to install?
Yes, the L180 mounts to a frame with a stop, and it's a full mortise part, so a pocket has to be cut in both the frame head and the top of the door. Use the Norton Rixson templates to locate the mortise pockets and screw holes, and confirm the lead lining position before any cutting starts. On a shielded leaf the screw pattern only works if the lining sits where the template assumes.
