Norton Rixson FML19LH-625 – Frequently Asked Questions

1) Will the Norton Rixson FML19 intermediate pivot work on a lead-lined X-ray room door?
That is exactly what the FML19 is built for. The screw holes are spaced to straddle the lead lining running down the center of the door, so the fasteners land on either side of the shielding instead of punching through it. It handles door thicknesses of 1-3/4, 2, 2-1/4, 2-1/2, or 3 inches, which covers the range lead-lined imaging doors usually land in once the shielding is laminated in.
2) Is the FML19 pivot rated for a 3 hour fire door assembly?
Yes, 3 hours. The FML19 carries a 3-hour fire rating with CAL FIRE 3725-0047:0108 certification. If your opening needs a 20-minute label instead, that is ordered with the -20 suffix.
3) Do I have to specify hand when ordering a Norton Rixson FML19 pivot?
Yes. The FML19 is a handed pivot, ordered left hand or right hand, and there is no reversing it in the field. Every finish is stocked both ways, so pick the hand off the door swing first, then the finish. Get the hand wrong and the pivot will not mount.
4) Can I use the FML19 on a center hung door?
No. The FML19 is a 3/4 inch offset, offset-hung pivot, so it only suits a door hung on offset top and bottom pivots or an offset floor closer arm. A center hung opening pivots on a different axis and needs center hung intermediate hardware. Match the intermediate pivot to whatever the floor closer and top pivot already establish.
5) Will the FML19 fit a 1-3/8 inch door?
No. The FML19 starts at 1-3/4 inches and goes up through 3 inches, in the listed thicknesses of 1-3/4, 2, 2-1/4, 2-1/2, and 3. A 1-3/8 inch leaf is the common older interior residential thickness and falls below what this pivot preps for. It is a commercial pivot, and 1-3/4 inches is the standard commercial door thickness it was drawn around.
6) I am replacing an intermediate pivot on an existing lead-lined door. What do I need to know before ordering the FML19?
Three things off the existing opening: the hand of the door, the door thickness (the FML19 covers 1-3/4, 2, 2-1/4, 2-1/2, and 3 inches), and whether the door is offset hung, since this pivot only works on a 3/4 inch offset arrangement. Confirm the mortise you are pulling the old pivot out of matches the FML19 template before you cut anything, because the screw pattern here is set to straddle the lead core rather than a generic hinge pattern.
7) What door height can an FML19 intermediate pivot support?
Doors from 60 to 90 inches tall. The FML19 is a load-bearing intermediate pivot, so it takes part of the door weight and holds alignment between the top and bottom pivots rather than just steadying the leaf. Heavy duty rating, non-ferrous base material.
8) What prep does the door need for an FML19 pivot?
Full mortise prep. You rout a mortise pocket in the door edge and drill per the Norton Rixson template, and the door edge is beveled 1/8 inch in 2 inches. Wood and machine screws come with the pivot; Torx screws are an option if you want a tamper-resistant head on an accessible opening.
9) Why would a door need an intermediate pivot instead of just top and bottom pivots?
Weight and height. On a heavy leaf, a lead-lined leaf, or a tall door, the top and bottom pivots alone let the door sag and drift out of alignment over time, which shows up as a dragging bottom edge or a latch that stops catching. An intermediate pivot like the FML19 sits between them, carries load, and holds the door in line. It is standard on doors in the 60 to 90 inch range running on floor closers in high traffic.
10) Is the FML19 an electrified pivot for power transfer through the door?
No. The FML19 is a mechanical load-bearing pivot with no wiring path through it. If you need power to an electrified lock or exit device on a pivot-hung door, that has to come from a separate electric power transfer or a raceway hinge, specified alongside the pivot set.
11) What finishes does the Norton Rixson FML19 come in?
Seventeen finishes, in both hands: 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 facility standardizing on one look, 626 satin chrome and 630-family finishes are the usual institutional default; painted 689 and 690 are the common match for aluminum and dark bronze frames.
