NGP 813-36 – Frequently Asked Questions

1) Will the NGP 813 saddle threshold fit a standard 36 inch commercial door opening?
The 813 comes in 36, 72, 82 and 96 inch lengths, so a standard 36 inch opening is a direct fit with no cutting. The longer lengths are there for pairs of doors and for wide storefront or institutional openings, and aluminum cuts down cleanly on site if your frame measures short of one of those sizes.
2) How high does the NGP 813 threshold sit, and will a door clear it?
It is a 1/4 inch high saddle, 8 inches across the width of the profile. That quarter inch is the rise your door bottom has to clear, so it works under doors undercut for a low sill without needing the door trimmed. The 8 inch width means it spans the full sill including the frame footprint on a typical commercial jamb.
3) Is the NGP 813 threshold BHMA certified, and what load is it rated for?
Certified to ANSI/BHMA A156.21 with a 1,000 lb load test. That is the number an institutional or MRO spec writer is looking for when the sill sits in a corridor taking carts, gurneys or pallet traffic.
4) Do I need to buy fasteners separately for the NGP 813 threshold?
Screws are in the box: #10 x 1-1/2 inch flat head zinc plated wood screws. Those are wood screws, so if you are anchoring into concrete or masonry you will need your own anchors and the supplied screws will not be used.
5) What is the difference between the NGP 813 and the Pemko 272 saddle threshold?
Both are 1/4 inch high flat saddle thresholds in aluminum. The width is the split: the 813 is an 8 inch profile, the Pemko 272 Series is 6 inches. Pick the 8 inch when the sill opening or the frame footprint is wider than a 6 inch plate will cover, and the 6 inch when you want less material sitting in the doorway.
6) What is the closest alternative to the NGP 813 saddle threshold when the opening only needs a 6 inch wide saddle?
The NGP 813 is a 1/4 inch high by 8 inch wide mill aluminum saddle threshold in 6063 T5 alloy, sold in 36, 72, 82 and 96 inch lengths. When the frame and floor transition only give you 6 inches of coverage, the Pemko 272 Series flat saddle threshold is the direct equivalent in the narrower width: it is a heavy-duty aluminum flat saddle at 1/4 inch by 6 inch. Same 1/4 inch height, so the door undercut and any bottom sweep stay the same; the difference is 2 inches of floor coverage on the saddle face. Measure from the stop to where you want the saddle to die into the floor before choosing between them.
7) Is there a slip resistant version of the NGP 813 threshold for wet entries?
The standard 813 has a fluted top, which gives some traction on its own. For wet or hazardous conditions NGP offers the SIA slip resistant finish as an option on the threshold, which you specify when ordering rather than adding later.
8) Can I order one threshold long enough to cover a pair of doors?
Yes. The 72, 82 and 96 inch lengths run a single continuous piece under a pair, which avoids a butt joint in the middle of the opening where water and dirt collect. Two 36 inch pieces are for single leaf openings.
9) Is a flat saddle threshold the same thing as the NGP 813, or is it a different part?
They are close but not identical in profile. The Pemko 272 Series is described as a flat saddle threshold at 1/4 inch by 6 inch in heavy-duty aluminum, meaning a plain flat top face. The NGP 813 is a 1/4 inch by 8 inch saddle with a fluted top surface, which adds traction underfoot in the doorway. If the specification calls for a slip resistant walking surface, the fluted face on the 813 matters, and NGP also offers an SIA slip-resistant finish for hazardous conditions. If the requirement is simply a flat aluminum transition at 1/4 inch, either profile answers it and the choice comes down to the 6 versus 8 inch width.
10) Is the NGP 813 threshold suitable for a high traffic building entrance?
It is a commercial rated saddle, 1,000 lb load tested per BHMA, in 6063 T5 aluminum. NGP lists it for office buildings, schools, healthcare, retail, industrial, multi-tenant residential and government facilities. For a fleet of openings you can standardize on it, but a mill finish sill in a heavy entry will show wear as scuffing on the raw aluminum.
11) Do I need a different saddle threshold for a double door or an unusually wide opening?
Not necessarily a different model. The NGP 813 saddle is stocked in 36, 72, 82 and 96 inch lengths, so a standard pair of 36 inch leaves is covered by a single 72 inch piece and wider frames by the 82 or 96 inch. Aluminum 6063 T5 at .125 inch typical wall cuts cleanly on site, so a long piece can be trimmed to the exact frame width. The Cal-Royal and Pemko saddles are the alternatives when the opening needs a fire rating or a 6 inch face, not when it simply needs more length.
