NGP 425EDKB 36 – Frequently Asked Questions

1) Will the NGP 425E saddle threshold work in a doorway where I need to keep the rise low for wheelchair and cart traffic?
The 425E saddle is 1/2 inch tall and 5 inches wide, so the rise a wheel or a foot has to cross is a half inch. If you need a lower profile than that, Pemko's 272 Series flat saddle is a 1/4 inch by 6 inch aluminum threshold and is described as ADA compliant. Both are aluminum saddles that sit on the floor under the door; the difference is height and width, so check what your door bottom clearance and any door sweep will tolerate before dropping from a 1/2 inch to a 1/4 inch rise.
2) What lengths does the NGP 425EDKB threshold come in, and can I cut it down for a 32 inch door?
Two lengths are stocked: 36 inches and 72 inches. The 36 inch piece covers a standard 3-0 single opening, and the 72 inch piece covers a pair of doors or gives you stock to cut. It is 6063-T5 aluminum with a typical .120 wall, so it cuts cleanly with a carbide blade on a miter saw. Cut ends leave bare aluminum, since the dark bronze anodizing is a surface finish and won't wrap the fresh cut.
3) Do I need to buy fasteners separately for the NGP 425E saddle threshold?
No separate hardware order needed. The threshold ships with #10 x 1-1/2 inch flat head zinc plated wood screws. Those are sized for wood subfloors and wood sills. If you are anchoring into concrete or a steel sill, you will need to supply your own anchors, since the included screws are wood screws.
4) Is a saddle threshold like the NGP 425E the right choice, or do I need a different threshold type for an exterior door?
A saddle is a flat transition piece that sits under the door across the opening. The 425E is a 5 inch wide, 1/2 inch high aluminum saddle with a fluted top, which gives the surface some texture for traction and lets water shed rather than pool. It seals against a door bottom sweep or shoe, so on an exterior opening you are pairing it with a sweep, not relying on the saddle alone. If your opening needs a raised stop or a thermal break to seal against weather without a sweep, a saddle profile is the wrong shape for the job.
5) What is the difference between the Cal-Royal CR2000 and CR3700 saddle thresholds?
Both are Cal-Royal saddle threshold series, and the split is the fire rating they carry. The CR2000 is described as fire rated and ADA compliant. The CR3700 is rated for 3-hour positive pressure. If your spec names an hourly rating and positive pressure at the sill, the CR3700 is the one written to that; the CR2000 pairs its fire rating with ADA compliance.
6) Will the dark bronze finish on the NGP 425E hold up in an exterior or high traffic opening?
The DKB dark bronze/black anodized coating is an anodized finish, not a paint, so it is integral to the aluminum and resists corrosion rather than chipping off an edge. The base metal is 6063 alloy in T5 temper. Anodized aluminum does show wear where shoes and cart wheels track over the same line, so on a heavily used entry expect the traffic path to brighten over time.
7) Can I use the NGP 425E saddle threshold to standardize thresholds across a commercial building?
It is specified for commercial use, and the 72 inch length lets you cut multiple openings out of one stick so the profile and the dark bronze finish match door to door. Every opening you put it on gets the same 5 inch wide, 1/2 inch high saddle, which matters when you are matching a corridor or a bank of tenant entries. Order the 36 inch pieces for single 3-0 doors and the 72 inch for pairs or for cut stock.
