NGP 425E 42 – Frequently Asked Questions
1) Will the NGP 425E saddle threshold fit a standard 36 inch door opening?
Yes. The 425E comes cut in 36, 42, 48, 60, 72, 84 and 96 inch lengths, so a standard 3-0 opening takes the 36 inch piece. The wider lengths cover pairs of doors and oversized frames, and aluminum extrusion cuts down cleanly on site with a miter saw if your frame measures short of a stock length.
2) How wide and how tall is the NGP 425E threshold, and how much clearance does the door need under it?
The 425E measures 5 inches wide by 1/2 inch tall. That half inch is the height the door bottom has to clear once the threshold is set on the floor, so undercut the door accordingly or you will bind. The 5 inch width gives room to land it under the full frame depth on a typical commercial jamb.
3) Is the NGP 425E ADA compliant for a barrier free opening?
For an accessible route the flat, low profile thresholds are the ones to look at. Pemko's 272 Series is an ADA compliant flat saddle threshold at 1/4 inch by 6 inches, and Cal-Royal's CR2000 saddle series is described as ADA compliant as well. Compare those against the 425E's 1/2 inch height before you commit on a barrier free opening.
4) What is a comparable saddle threshold to the NGP 425E if I need a fire rated opening?
The NGP 425E is a 5 inch wide by 1/2 inch tall mill aluminum saddle threshold with a fluted top, extruded from 6063-T5 alloy. For an opening where the threshold has to carry a fire rating, the Cal-Royal CR2000 saddle threshold is the peer to look at: it is described as a fire rated and ADA compliant saddle design. Both are saddle profile thresholds that mount under the door across the opening, so the swap is the same kind of installation.
5) What is the NGP 425E threshold made of and will it hold up outdoors?
Extruded aluminum alloy 6063 in T5 temper, with a .109 inch typical wall thickness. That alloy and temper is the standard architectural extrusion, and it resists weathering and corrosion, so it holds up at an exterior entrance as well as an interior transition. Mill finish is the natural, uncoated aluminum look.
6) Does the NGP 425E threshold come with fasteners, or do I need to buy screws separately?
Screws are in the box: #10 x 1-1/2 inch flat head zinc plated wood screws. Those are sized for anchoring into a wood substrate. If you are setting into concrete you will need your own anchors, since the supplied screws are wood screws.
7) What does the fluted top on a saddle threshold do, and do I need it?
The flutes are raised ridges running the length of the 425E that break up a wet shoe contact and give traction underfoot. It matters on entrances that see rain, snowmelt or mopping. A smooth flat top, like the Pemko 272 flat saddle, is easier to roll carts and chairs across but gives you less grip. NGP also offers an optional SIA slip-resistant finish on this profile for hazardous conditions.
8) Can I standardize the NGP 425E across a whole building's exterior doors?
It is built for commercial duty, and the seven stock lengths from 36 up to 96 inches cover single doors, pairs and wide frames off one part number, which keeps a facility on one profile and one look. Mill aluminum finish is consistent piece to piece. Where an opening is fire labeled or on an accessible route, pull that one from a rated or low profile series instead of forcing the 425E in.
9) Is the Pemko 272 a drop-in replacement for an NGP 425E?
Not dimensionally. The Pemko 272 is a flat saddle threshold at 1/4 inch by 6 inches, while the NGP 425E is 1/2 inch by 5 inches with a fluted top. Swapping one for the other changes both the width of the threshold across the floor and the height the door has to clear, which affects door undercut and any bottom sweep or door bottom already fitted. Treat it as a different profile to be sized to the opening, not a like-for-like part swap.
10) For a high traffic commercial entrance, which saddle threshold gives the best footing - the NGP 425E, Cal-Royal CR2000, or Pemko 272?
The NGP 425E is the one in that group with a fluted top surface, which is the ribbed walking face that adds slip resistance, and it can be had with an optional SIA slip-resistant finish for hazardous conditions. The Pemko 272 is a flat saddle threshold, a smooth walking face at 1/4 inch by 6 inches. The Cal-Royal CR2000 is a saddle threshold with a fire rated and ADA compliant design. If traction on the threshold itself is the deciding factor, the fluted face on the 425E is the distinguishing feature.
11) What is the difference between the Cal-Royal CR2000 and CR3700 saddle thresholds when I am cross-shopping against the NGP 425E?
Both Cal-Royal parts are saddle thresholds like the NGP 425E, which is a 5 inch by 1/2 inch mill aluminum saddle with a fluted top. Between the two Cal-Royals, the CR2000 is a fire rated and ADA compliant saddle design, while the CR3700 is specified with a 3-hour positive pressure fire rating. If the drawing calls out a positive pressure test on the assembly, that is what separates the CR3700 from the CR2000.
