NGP 325-36 – Frequently Asked Questions

1) Will the NGP 325 half saddle threshold meet ADA at my door opening?
The 325 is ADA compliant when it's installed with the non-beveled edge flush with the flooring, or where no more than a 1/4 inch vertical rise occurs. The extrusion itself is only 1/2 inch tall, so if you set it on top of finished flooring you're above the 1/4 inch change-in-level allowance unless the floor is built up to it. On slab or with a recessed/flush condition it works. Fluted top surface adds traction underfoot.
2) What lengths does the NGP 325 saddle threshold come in?
Seven cut lengths: 36, 42, 48, 60, 72, 76 and 84 inches. For a standard 36 inch single door leaf the 36 inch piece covers the opening; 72 and 76 inch cover a pair of 36 inch leaves, and 84 inch handles wider pairs or openings where you want to run past the jambs. Aluminum extrusion cuts down cleanly on site with a miter saw if you need an in-between size.
3) Do I need to buy fasteners for the NGP 325 threshold?
Screws come with it. Each 325 ships with #10 x 1-1/2 inch flat head zinc plated wood screws for mounting; dark bronze screws are supplied with DKB finish thresholds instead. Those are wood screws, so for a concrete slab plan on masonry anchors or sleeve anchors sized to the same screw holes.
4) What else could I use instead of the NGP 325 if 1/2 inch is too tall for my ADA transition?
The Pemko 272 Series is a flat saddle threshold at 1/4 inch x 6 inches in heavy-duty aluminum, and it is ADA compliant. A 1/4 inch height sits right at the vertical rise limit even when set on top of finished flooring, so it is the safer pick when you cannot recess the threshold or build the floor up to it. The 325 at 1/2 inch needs the flush or recessed condition to comply.
5) What is the difference between the NGP 325 half saddle threshold and the Pemko 272 saddle threshold?
Both are ADA compliant aluminum saddle thresholds, but they differ in profile. The NGP 325 is a half saddle 5 inches wide and 1/2 inch tall with a fluted top in aluminum alloy 6063 T5 and a mill finish. The Pemko 272 is a flat saddle at 1/4 inch by 6 inches in heavy duty aluminum. The 325 gives you a taller 1/2 inch rise across a 5 inch run; the 272 is the lower, wider flat profile at 1/4 inch over 6 inches. If the floor transition you are covering needs the wider footprint and the lowest possible rise, the 272 profile is the one to look at.
6) Why is it called a half saddle, and where do you use one instead of a full saddle?
A half saddle is a one-sided ramp: the 325 is 5 inches wide and 1/2 inch tall, so it rises on one side and finishes flat, rather than sloping down on both faces the way a full saddle does. That suits a doorway where the two floors are at different heights, or where the threshold butts a slab or carpet edge on one side. If your floor levels match on both sides of the opening and you need a symmetrical transition, a full saddle profile is the better call.
7) Will a 5 inch wide threshold cover my door frame footprint?
At 5 inches wide the 325 spans a standard commercial frame with roughly .250 inch typical wall thickness and leaves coverage on both sides of the door. If you're carrying a deeper frame or need more floor coverage under the sweep, the Pemko 272 Series runs 6 inches wide. Width is what decides whether the threshold hides the floor cut and the frame anchors, so measure the frame throat before ordering.
8) Can I standardize the NGP 325 across all the exterior doors in a building?
Yes, and that's the usual reason to spec it. One profile in seven lengths from 36 to 84 inches covers single leaves and pairs, the mill finish is neutral against any frame color, and the fluted top gives the same walking surface at every opening. Order the 36 inch for single doors and the 72 or 76 inch for pairs, and keep a couple of long pieces for out-of-standard openings since the extrusion cuts to length.
9) Can I use a Pemko 272 in place of an NGP 325 on the same opening?
They are not a drop in swap even though both are ADA compliant aluminum saddles. The NGP 325 half saddle measures 5 inches wide by 1/2 inch tall and ships with #10 x 1-1/2 inch flat head zinc plated wood screws. The Pemko 272 is a flat saddle at 1/4 inch by 6 inches, so it is an inch wider across the floor and half the height. Swapping one for the other changes the footprint the anchors land in and changes the rise the door bottom and any sweep have to clear, so the opening has to be measured for the new profile rather than reusing the existing layout.
