NGP 5X427BRX424BR-36 – Frequently Asked Questions

1) Does the NGP floor closer threshold come with fasteners, or do I need to buy anchors separately?
Screws are in the box. The threshold ships with #10 x 1-1/2 inch brass wood screws in an antique bronze finish, chosen to disappear against the dark bronze extrusion. Those are wood screws, so they suit a wood subfloor or plugged/shielded holes. If you're setting this into concrete, which is the usual case at a floor closer, you'll need to supply your own anchors sized for the 1-1/2 inch embedment.
2) Will this NGP saddle threshold work with a Rixson or Dor-O-Matic floor closer, or is it closer-specific?
Not closer-specific. The 5X427BR/424BR can be fabricated to suit any floor closer system, so the cutout at the 7 inch wide section is made to the closer you're actually installing rather than to one manufacturer's pattern. Give the closer model and the cement case dimensions when you order so the fabrication matches.
3) Should I use a floor closer threshold or a standard saddle threshold under my door?
It depends on whether there's a closer in the floor. A plain saddle threshold is a constant-width strip and has nowhere to sit over a cement case. The NGP 5X427BR/424BR is the floor closer version: it widens to 7 inches through the closer area to cover the case and cover plate, then returns to the 4 inch wide by 1/4 inch tall saddle for the rest of the run. If your door swings on butt hinges or an offset pivot with no floor closer, you don't need the wide section and a straight saddle is the simpler part.
4) Is the bronze on the NGP 5X427BR threshold going to match my US4 satin bronze door hardware?
Close match. The finish is architectural bronze satin, NGP finish code 728, described as similar to US4. It's an alloy CDA 385 (copper alloy C38500) extrusion, so the bronze is the metal itself rather than a coating, and it will patina on its own over time the way solid bronze does. Plated US4 hardware on the door won't age the same way, so expect the threshold to drift slightly over a few years in a high-traffic entry.
5) Is a 1/4 inch tall saddle threshold low enough to be walked over in a main entrance corridor?
At 1/4 inch tall across the 4 inch wide saddle section, this NGP threshold sits low enough that it reads as a flush transition rather than a step, which is why saddle profiles like this get used in office and healthcare corridors where carts and wheeled traffic cross constantly. The top face is fluted, which adds traction underfoot. For wet entries and pool or kitchen areas, NGP offers an SIA slip-resistant finish on this threshold as an option.
6) Is the NGP 5X427BR threshold rated for commercial traffic or is it a residential part?
Commercial. NGP builds this one out of alloy CDA 385 architectural bronze at a .187 inch typical wall, and it's specified into office buildings, schools, hospitals, retail, warehouses, multi-tenant residential, and government facilities. The bronze alloy also holds up to corrosion at an exterior entry better than an anodized aluminum saddle does.
