NGP 322 – Frequently Asked Questions

1) Will the NGP 322 saddle threshold meet ADA requirements for an accessible opening?
The 322 half saddle is ADA compliant when it's installed with the non-beveled edge flush to the flooring, or where the vertical rise it creates is no greater than 1/4 inch. At 1/2 inch tall overall, that means the flush-to-floor detail matters: set on top of finished flooring with the full 1/2 inch exposed on one side, you're past the 1/4 inch unbeveled rise an accessible route allows. Recess it or bring the floor up to it.
2) Is a 3 inch wide threshold wide enough, or do I need a 6 inch saddle?
A half saddle like the NGP 322 covers 3 inches of the opening, which suits a single-swing door where you only need to cover the joint on one side of the door stop, or a floor transition under the door. Full saddles run under the door and past the stop on both sides. If you're covering a wide frame condition or a double-egress detail, step up to something like the Pemko 272 Series flat saddle at 1/4 inch x 6 inches, which gives twice the coverage at half the height.
3) Do I need to order screws separately for an NGP 322 threshold?
Fasteners come with it. Each 322 ships with #10 x 1-1/2 inch flat head zinc plated wood screws, and dark bronze screws are supplied with the DKB (dark bronze) thresholds so the heads don't stand out against the finish. Wood screws mean a wood sub-floor or blocking; anchoring into concrete you'll want your own sleeve or lag anchors sized to a #10 head.
4) Can I swap an NGP 322 in where an old 1/4 inch flat saddle was?
Height is the catch. The 322 stands 1/2 inch, so dropping it in where a 1/4 inch flat saddle sat raises the transition by another 1/4 inch and changes the clearance the door bottom and sweep are set to. Check the undercut of the door leaf first. If you need to hold the existing height, a 1/4 inch profile like the Pemko 272 Series matches the old saddle's rise.
5) For a facility standardizing thresholds across many openings, how do the NGP 322 and the Cal-Royal saddle series differ?
The NGP 322 is a single half saddle profile, 3 inches wide by 1/2 inch tall in 6063-T5 aluminum with a fluted top, supplied in mill aluminum or dark bronze. The Cal-Royal CR2000 and CR3700 are saddle threshold series, so a facility standardizing on one of them is picking from a family of profiles; the CR3700 series carries a 3-hour positive pressure fire rating and the CR2000 series is a fire rated, ADA compliant design. A common approach is to run a series across labeled openings and a fixed profile like the 322 where the opening is unlabeled.
6) What finishes does the NGP 322 half saddle come in?
Two: mill aluminum and dark bronze. Mill is the raw silver extrusion finish and it's what most people run when the frames are aluminum or the threshold sits under a storefront. Dark bronze matches bronze-anodized entrances and oil-rubbed door hardware, and the bronze version ships with matching bronze screws. Both are the same 3 inch by 1/2 inch fluted profile.
7) Is the top of the NGP 322 threshold slippery when wet?
The top face is fluted, meaning ribbed across the walking surface rather than smooth, which is what gives traction underfoot at an entry that sees rain or snow tracked in. That's the practical difference between this and a flat-top saddle: a flat saddle is easier to seal a sweep against, a fluted top is better where people are walking over it wet.
8) What does a thermal break threshold actually do for me on an exterior door?
The 322 is built for thermal break applications, which breaks the conductive path from the outdoor slab to the indoor floor through the metal saddle. On a heated or cooled building that stops the threshold from running cold, sweating, and dumping condensation onto the finished floor inside the door. On an interior transition it buys you nothing, so a plain flat saddle covers it.
