NGP 315DKB – Frequently Asked Questions

1) Will the NGP 315BR half saddle threshold meet ADA at the doorway?
The 315BR is a 1/4 inch tall half saddle, and at that height it meets accessibility requirements when it's set with the non-beveled edge flush to the flooring, or anywhere the vertical rise it creates is no greater than 1/4 inch. If you're dropping it on top of a finished floor and leaving that 1/4 inch edge standing proud on the approach side, you've created the rise rather than eliminated it. Recess or feather the flooring to the non-beveled side and the profile does what it's meant to do.
2) Do I need to buy screws and anchors separately for the NGP 315BR threshold?
Screws come with it. The 315BR ships with #10 x 1-1/2 inch brass wood screws in an antique bronze finish, so the fasteners match the bronze rather than standing out as bright steel heads. Note they're wood screws, sized for a wood subfloor. Going down into concrete, you'll need your own masonry anchors or a lead-shield setup to suit; the supplied screws won't hold in slab.
3) I need a wider ADA threshold than 3 inches, what else is there?
The 315BR covers a 3 inch footprint, which handles a typical single door jamb transition. For a wider floor joint, a double door opening, or where you're bridging a bigger gap between two flooring materials, the Pemko 272 Series is a flat saddle threshold in the same 1/4 inch height but 6 inches wide, in heavy-duty aluminum, and it's also ADA compliant. Same low-rise transition, twice the coverage, though aluminum rather than bronze, so it won't match bronze hardware on the opening.
4) Can I use the NGP 315BR half saddle on a fire rated door opening?
For a labeled fire door assembly, spec a threshold that carries the rating in its own listing. Cal-Royal offers saddle thresholds built for that: the CR 2000 Series is fire rated and ADA compliant, and the CR 3700 Series carries a 3-hour positive pressure fire rating. On a non-labeled opening, a corridor transition, an interior floor joint, or a stair landing, the 315BR bronze half saddle is the one to use and gives you a finish match to bronze door hardware that the rated aluminum profiles won't.
5) What is a half saddle threshold and when do I use one instead of a full saddle?
A half saddle like the NGP 315BR is a single-sided transition strip, 3 inches wide, that sits under one side of the door rather than spanning the full opening with a raised center. Use it where you're covering a floor joint or a transition between two finished floors at an interior or light-duty exterior opening, and you don't need the raised stop a full saddle gives you for door-bottom sealing. If the opening needs a weather seal and a positive stop for a door bottom or sweep to close against, a full saddle profile is the one to spec. The 315BR is for the low, flat transition.
6) Is the NGP 315BR bronze threshold solid bronze or plated?
Solid material, not a plating. The 315BR is extruded from Alloy CDA 385, also written as Copper Alloy No. C38500, which is architectural bronze. The satin architectural bronze finish is NGP's 728, similar to US4. Because the bronze runs through the extrusion, foot traffic wearing the fluted top won't expose a different base metal underneath, which is the practical difference from a plated or anodized aluminum strip in a high-traffic entry.
7) Will a bronze threshold corrode where it meets an aluminum door frame or aluminum sill?
Worth thinking about before you set it. CDA 385 bronze is a copper alloy, and copper alloys in direct wet contact with aluminum set up galvanic action that eats the aluminum over time. On a dry interior transition it's a non-issue. At an exterior opening where the 315BR would land hard against an aluminum sill or storefront frame with water sitting in the joint, isolate the two with sealant or a bedding compound, or use an aluminum threshold such as the Pemko 272 Series instead and keep the materials the same.
8) Is an aluminum saddle threshold a direct substitute for the NGP 315BR bronze threshold?
Dimensionally they are not the same part. The NGP 315BR is 1/4 inch tall by 3 inches wide in Alloy CDA 385 copper alloy with an architectural bronze satin finish and a fluted top, and ships with #10 x 1-1/2 inch brass wood screws in an antique bronze finish. The Pemko 272 Series is a 1/4 inch by 6 inch heavy-duty aluminum flat saddle. The heights match at 1/4 inch, so the door clearance is unchanged, but the 6 inch width covers a different footprint at the sill and the aluminum flat surface will not match bronze door hardware the way the 315BR does.
9) What is the difference between the Cal-Royal CR2000 and the CR3700 saddle thresholds?
Both are Cal-Royal saddle threshold series. The CR 2000 Series is described as fire rated with an ADA compliant design. The CR 3700 Series carries a 3-hour positive pressure fire rating. If the opening is rated under positive pressure testing, the CR3700 is the series that names that rating; the CR2000 is the fire rated ADA series.
10) For a facility standardizing thresholds across many doors, how do the NGP 315BR and the Cal-Royal saddle series compare?
The NGP 315BR is a single 1/4 inch by 3 inch half saddle profile offered in Bronze and Dark Bronze finishes, so it standardizes on one width and one material family across the openings that take it. Cal-Royal offers the CR 2000 Series and the CR 3700 Series, which are series-level saddle programs, the CR2000 fire rated and ADA compliant and the CR3700 rated 3-hour positive pressure. A facility with a mix of rated and unrated openings often pairs the finish-matched bronze half saddle at the non-rated doors with a Cal-Royal series at the labeled ones.
11) Is the fluted top on a bronze threshold slippery when wet?
The fluting is there for exactly that reason. The 315BR's top face is fluted rather than smooth, which breaks up the surface and gives a shoe sole something to bite on across an otherwise polished bronze strip. It also hides scuffing better than a plain face. At 1/4 inch tall the flutes are shallow enough that a door bottom clears and a cart wheel rolls over without catching.
12) Is the NGP 315BR bronze threshold rated for commercial traffic or is it a residential part?
Commercial. NGP classes the 315BR as a commercial product, and the .157 inch wall in solid CDA 385 bronze is what backs that up under the foot and cart traffic in office buildings, schools, hospitals, retail, warehouses, multi-tenant residential, and municipal buildings. Bronze also takes exterior exposure without the corrosion problems a plated steel strip has.
