NGP 913-36 – Frequently Asked Questions
1) Will the NGP 913 saddle threshold work under a standard 36 inch commercial door opening?
Yes. The 913 comes in a 36 inch length that covers a standard 3-0 opening, and it also runs 56, 72, 74 and 80 inches for pairs, wider frames and door assemblies where you want a single continuous piece. The saddle is 9 inches wide across the opening and 1/4 inch tall, so it sits flat between the jambs rather than building a ramp. Cut to length in the field if your frame opening is between sizes.
2) How much undercut do I need on the door for a 1/4 inch saddle threshold?
The 913 saddle stands 1/4 inch above the finished floor, so the door bottom has to clear that 1/4 inch plus whatever sweep or bottom seal you are running on top of it. It is a flat 9 inch wide saddle, not a ramped or interlocking threshold, so the clearance math is simply 1/4 inch of rise across the full width of the opening.
3) Is the NGP 913 threshold ADA compliant for a barrier free opening?
At 1/4 inch tall the 913 saddle is a flat threshold with no bevel required, which is why quarter inch saddles get specified on accessible openings. It is BHMA certified to ANSI/BHMA A156.21 and load tested to 1,000 lb. If your spec calls out a threshold by a stated ADA designation rather than by height, the Pemko 272 Series is a flat saddle marketed as ADA compliant, in a 1/4 inch x 6 inch profile.
4) Is the NGP 913 a weatherstrip threshold or just a floor plate?
It is a flat saddle, a 9 inch wide by 1/4 inch tall plate that covers the floor joint and gives the door bottom something clean to close against. There is no vinyl insert, no stop and no drain channel in the profile. If you need the opening sealed against wind and water, pair it with a door bottom sweep or an automatic door bottom on the door itself, or specify an interlocking or thermal barrier threshold instead.
5) Is the Pemko 272 a drop-in replacement for an NGP 913 that is coming out of a door sill?
Not on width. The NGP 913 is 9 inches wide with a 1/4 inch height and a fluted top; the Pemko 272 Series is a flat saddle at 1/4 inch by 6 inches. The heights match, so the rise over the finished floor is the same, but a 6 inch saddle set into an anchor pattern drilled for a 9 inch saddle leaves 3 inches of the old footprint exposed and the outer fastener line unsupported. Swapping between the two means re-drilling the sill. The two also differ in walking surface: the NGP 913 top is fluted for traction, with an optional slip-resistant finish, while the Pemko 272 is described as flat.
6) What is the difference between a 9 inch and a 6 inch wide saddle threshold?
Width is about how much floor you are covering, not about strength. The NGP 913 at 9 inches spans a wider gap, which is what you want where the sill, floor transition or old threshold cutout is broad, or where two different floor finishes meet under the door. The Pemko 272 Series covers the same 1/4 inch height in a 6 inch width, which suits a tighter sill or a single door where the floor break is narrow. Measure the exposed gap between finishes before you pick.
7) Do I have to buy screws separately for the NGP 913 threshold?
No, fasteners come with it. Each 913 saddle ships with #10 x 1-1/2 inch flat head zinc plated wood screws. Those are wood screws, so if you are anchoring into concrete or a steel sill pan you will need your own anchors and a matching bit.
8) Does the NGP 913 saddle threshold come in dark bronze to match my other doors?
Two finishes, and both run the full length range. Mill aluminum is the natural extruded finish, and dark bronze is available in every length the 913 offers: 36, 56, 72, 74 and 80 inches. For a building where you are standardizing across many openings, pick one finish and one length and repeat it.
9) Is the fluted top on a saddle threshold slip resistant enough for an entrance?
The fluted top on the 913 is a machined texture across the walking surface, which gives more traction than a plain flat saddle. For a wet entry, a ramp landing, or anywhere the floor takes weather, NGP offers the threshold with an SIA slip resistant finish instead, which is an abrasive surface rather than just flutes. Specify SIA at order time.
10) How do I order one threshold for a pair of doors instead of two pieces?
Take the full frame opening width, not the door width, and order the next length up. The 913 runs to 80 inches, so a 6-0 pair (about 72 inches of clear opening) is covered by the 72, 74 or 80 inch piece and gets cut to fit. A single continuous saddle under a pair avoids a seam at the meeting stile, which is where water and dirt track through.
11) Can I install the NGP 913 over an existing worn threshold?
Usually not directly. At 1/4 inch tall the 913 is meant to lie on the finished floor or sill, and stacking it on an old saddle adds height the door was never undercut for. Pull the old threshold, clean the sill flat, then set the 913 and fasten through it with the supplied #10 x 1-1/2 inch screws. If the old cutout in the flooring is wide, the 9 inch width is what covers it.
12) What is the difference between the Cal-Royal CR2000 and the CR3700 saddle thresholds?
Both are Cal-Royal saddle thresholds. The CR2000 is a fire rated and ADA compliant saddle design in the CR 2000 Series. The CR3700, in the CR 3700 Series, carries a 3-hour positive pressure fire rating. Where the specification names a positive pressure rating and a 3-hour duration, the CR3700 is the one that states it; where the requirement is a rated saddle that also has to meet ADA, the CR2000 states both.
