NGP 323DKB-75 – Frequently Asked Questions

1) Will an NGP 323DKB half saddle threshold meet ADA at the door opening?
The 323 half saddle stands 1/2 inch tall, which is over the 1/4 inch ADA allows as an unbeveled vertical rise. NGP calls it ADA compliant when the non-beveled edge sits flush with the flooring, or where the exposed rise is no greater than 1/4 inch. In practice that means recessing it or bringing finish floor up to it on the high side. Drop it on top of finished floor with the full 1/2 inch exposed and you are outside the requirement.
2) What length NGP 323 dark bronze threshold do I need for a standard 3-0 door?
The 323DKB comes in 75 inch and 96 inch lengths, both in dark bronze. A single 3-0 leaf needs about 36 inches of frame opening, so the 75 inch piece is cut down for one door and the 96 inch piece covers a pair of doors or a 6-0 opening in one run without a seam at the astragal. Aluminum cuts cleanly with a miter saw and a non-ferrous blade.
3) Do I need to buy fasteners with the NGP 323 threshold or are screws included?
Screws come with it. NGP supplies #10 x 1-1/2 inch flat head zinc plated wood screws, finish-matched to the dark bronze. Those are wood screws, so for a concrete slab you will need masonry anchors instead, sized to the same #10 hole. Nothing else is required to set the threshold itself.
4) Is a 3 inch wide threshold enough to sit under a 1-3/4 inch commercial door?
Three inches of width gives you the door's 1-3/4 inch footprint plus roughly an inch and a quarter of extra bearing, which is enough to land the door edge and still catch floor on the interior side. Where the 323 will not work is under a pair of doors with an overlapping astragal or where a wider landing is called out for a door bottom sweep to seal against. For a wider run, the Pemko 272 Series is a 6 inch flat saddle.
5) I need a threshold on a fire rated opening - is the NGP 323 the right choice or should I look at a Cal-Royal?
For a fire rated opening, look at the Cal-Royal saddle thresholds. The Cal-Royal CR2000 Series is a saddle threshold offered with a fire rated and ADA compliant design, and the Cal-Royal CR3700 Series carries a 3-hour positive pressure fire rating. The NGP 323 half saddle is an aluminum alloy 6063 T5 saddle that is ADA compliant when installed flush or with no more than a 1/4 inch vertical rise, and it is specified for commercial applications on that basis. If the opening carries a fire label, the CR2000 or CR3700 is the series to spec.
6) My opening needs a wider threshold than 3 inches - what should I use instead of the NGP 323?
Step up to the Pemko 272 Series, a flat saddle threshold at 6 inches wide in heavy-duty aluminum with an ADA compliant design. The NGP 323 half saddle is 3 inches wide with a 1/2 inch height, which suits a narrow transition; where the sill or the floor break is wider than the 3 inch face can bridge, the 6 inch Pemko 272 covers it in one piece.
7) What is a half saddle threshold and when do I use one instead of a full saddle?
A half saddle covers only one side of the opening, so it butts against the floor on the other side rather than ramping down both ways. It is the piece to use when you are transitioning to a floor that comes up to meet it, or when you only need to cap one edge, typically an interior or protected opening. A full saddle ramps down on both faces and is what you want when the finish floor is level on either side and you need a symmetrical transition. The 323 is the half saddle version at 1/2 inch high by 3 inches wide.
8) Will an aluminum saddle threshold hold up in a high traffic entrance?
The 323 is extruded from 6063 aluminum in T5 temper with a .109 inch typical wall, and the top face is fluted rather than smooth, which gives the tread surface some bite underfoot and hides scuffing. That is the standard commercial threshold construction and it is what NGP rates for office, school, healthcare, retail and warehouse openings. Aluminum will show wear in a heavy cart route, but it does not rust.
9) Can I use the NGP 323 to replace a worn threshold and match the other doors in my building?
Dark bronze is the only finish the 323 is offered in, so it matches openings already running bronze or dark anodized hardware and will stand out against an aluminum mill finish run. Because it is a half saddle at 1/2 inch, swapping it in for a taller or double-ramped saddle changes the floor transition and may leave the old fastener holes exposed, so check the height of what is coming out before you standardize on it across a property.
10) I am standardizing thresholds across a building - can I mix NGP 323 and Cal-Royal saddles on different doors?
They can coexist, but they are not visually or dimensionally matched. The NGP 323 half saddle comes in dark bronze with a fluted top in 75 inch and 96 inch lengths, cut to a 3 inch width and 1/2 inch height. The Cal-Royal CR2000 and CR3700 are separate saddle threshold series with their own profiles, the CR3700 carrying a 3-hour positive pressure fire rating. A common approach in a mixed facility is to run one series on the labeled openings and the other on the rest, accepting that the two will read differently underfoot.
