Norton Rixson EH345 4 622 – Frequently Asked Questions

1) Will the Norton Rixson EH345 top pivot work with my existing center hung bottom pivot or floor closer?
The EH345 mates with any center hung bottom pivot or floor closer whose pivot point sits 2-3/4 inches (70mm) or more from the door edge. Measure from the door edge to the centerline of the bottom pivot on what's already in the floor. Anything less than 2-3/4 inches and the top and bottom pivot points won't line up, so you'd need a different top pivot or a different floor closer.
2) Is the EH345 the right top pivot for a door over 8 feet 6 inches tall?
That's exactly what it's built for. The EH345 is a walking beam type top pivot for doors over 8'6" in height, using a longer throw pin that engages 1-3/4 inches (44mm) up into the top of the door. On a shorter door the extra throw isn't needed, but on a tall leaf it's what keeps the head of the door under control.
3) How many wires can I run through the EH345 electrified pivot, and what gauge are they?
Wire count is an ordering choice: two, four, six, eight or twelve. The two-wire version is 18 gauge; four through twelve wire versions are 24 gauge and ElectroLynx compatible. Pick by the load you're transferring, 18 gauge two-wire suits a single higher-draw device like an electric latch retraction or a strike, while the 24 gauge multi-wire versions are for lock power plus monitoring and request-to-exit signals back to the panel. Count every conductor your device schedule calls for before you settle on a wire count, because the pivot is not field-upgradable to more wires.
4) Can I use the EH345 pivot on a fire rated door opening?
The EH345 does not carry a fire rating, so it isn't the pivot for a labeled opening. On a fire rated tall door you need hardware carrying the label for that assembly. Where the EH345 fits is non-rated tall commercial entrances, lobby and grand entrance leaves, and interior monumental doors that need power run through the top of the door.
5) Does the EH345 pivot need to be ordered left hand or right hand?
No handing to specify. The EH345 is non-handed, so one part covers both left and right hand openings. For a property manager or facility stocking spares across a building, that means a single pivot on the shelf instead of a matched pair of handed items.
6) Why would I pick a walking beam pivot over a standard top pivot in a building that has settled?
Settling closes up or opens the gap at the head, and a short pin can walk out of the door. The EH345 uses a walking beam type design with an 11/16 inch (17mm) diameter pin that throws 1-3/4 inches (44mm) into the door top, so there's engagement left to spare when the frame moves. That extra throw is the reason to specify it on older buildings or new construction where movement is expected, rather than a shallower standard top pivot.
7) Do I need to buy mounting screws separately for the EH345 pivot?
Screws come with it. The EH345 is furnished with both wood and machine screws, so it covers a wood frame or a hollow metal frame out of the box. What isn't in the box is the bottom half of the system, you still need a center hung bottom pivot or floor closer, plus the wiring harness and power supply for the electrified side.
8) Is a center hung pivot like the EH345 the right choice, or should I be looking at offset pivots?
Center hung means the door swings on an axis roughly in the middle of the door thickness, so the leaf pivots in the opening and can swing both ways. That is the arrangement for balanced and double-acting entrance doors and for anything sitting over a center hung floor closer. Offset pivots hang the door outboard of the frame face and are the single-acting arrangement used with a concealed overhead or offset floor closer. The EH345 is a center hung top pivot, and it only works over center hung bottom hardware, so confirm what's in the floor before you order.
9) Can the EH345 carry power for an electrified lock on a heavy tall door?
That's the point of it. The EH345 is a heavy duty electrified pivot with a needle bearing, so it takes the weight of a tall commercial leaf while transferring power through the pivot instead of through a surface door loop or an electric hinge. On a center hung door there's no hinge edge to run a transfer through, which is why the power has to come through the pivot. Specify the wire count to match the device load and signalling you need.
10) What finishes does the Norton Rixson EH345 come in?
Ten finishes, all available with any of the wire counts: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed satin bronze, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome and 626 satin chrome. On a center hung installation most of the pivot is buried in the door and frame, so match the visible plate to the rest of the door hardware, 626 and 630-family satin finishes are the usual commercial default.
