NGP 327-36 – Frequently Asked Questions

1) Will the NGP 327 half saddle threshold work under a door where I can only give up 1/2 inch of height?
That is exactly its profile. The 327 is a half saddle measuring 4 inches wide by 1/2 inch tall, so the raised height at the opening is 1/2 inch. Half saddle means the ramp runs on one side only, so it sits against a jamb or a flush transition rather than sloping both directions like a full saddle.
2) Is the NGP 327 threshold ADA compliant for a barrier-free opening?
It meets accessibility requirements when installed with the non-beveled edge flush with the flooring, or anywhere the vertical rise is no greater than 1/4 inch. Set on top of a finished floor with the full 1/2 inch standing proud on the non-beveled side, that condition is not met. The compliance depends on how you set it, not on the extrusion alone.
3) Do I need to buy fasteners separately for the NGP 327 threshold?
Screws come with it. Each piece ships with #10 x 1-1/2 inch flat head zinc plated wood screws, and the dark bronze finish version ships with dark bronze screws so the heads match the extrusion. Wood screws are what you get, so an anchoring situation in concrete or masonry means supplying your own anchors.
4) Can an aluminum half saddle threshold be used on a fire rated door opening?
For an opening carrying a fire label, specify a threshold that is itself listed for that use. The Cal-Royal CR2000 saddle threshold series is a fire rated and ADA compliant design, and the Cal-Royal CR3700 series carries a 3-hour positive pressure fire rating. The NGP 327 half saddle is a 4 inch wide by 1/2 inch tall 6063-T5 aluminum profile with a fluted top, described as ADA compliant when installed with the non-beveled edge flush to the flooring or where no greater than 1/4 inch vertical rise occurs, and it suits commercial office, education, healthcare, retail, industrial, multi-tenant residential and government openings. On a stair enclosure, corridor cross-door or other labeled opening, the CR3700 with its 3-hour positive pressure rating is the one to price.
5) What finishes does the NGP 327 saddle threshold come in?
Three: mill aluminum, architectural bronze and dark bronze, and all three are offered in every stock length (36, 72 and 80 inches). Mill is the raw aluminum finish and takes paint or anodizing if a job calls for a custom color. Architectural bronze and dark bronze are anodized and are what most people pick to match bronze frames and dark hardware.
6) Half saddle or full saddle threshold, which do I need?
A half saddle like the NGP 327 ramps on one side and ends square on the other, so it suits a transition where one side is already at height, an interior opening against a raised floor, or where the flat edge tucks against a jamb or existing sill. A full saddle ramps both directions and is the choice where both sides of the opening are at the same finished floor level and traffic crosses in both directions. Getting this backwards leaves a square 1/2 inch lip in the path of travel.
7) Which saddle threshold matches the bronze finish on the rest of the doors in a building?
The NGP 327 half saddle is stocked in three finishes -- mill aluminum, architectural bronze and dark bronze -- each in 36 inch, 72 inch and 80 inch lengths, so single doors and pairs can be run in one finish across a floor. Dark bronze units are supplied with dark bronze #10 x 1-1/2 inch flat head screws so the fasteners do not read against the threshold. Mill finish also accepts paint or anodizing if a custom color is required. The Cal-Royal CR2000 and CR3700 saddle series and the Pemko 272 flat saddle are the comparable saddle profiles to price alongside it when a different height or a fire rating drives the choice.
8) Can the NGP 327 threshold be used in a thermal break assembly?
Yes, the 327 is intended for thermal break applications, which is what you want on an exterior opening where an uninterrupted aluminum path from outside to inside would conduct heat and invite condensation at the sill. On a purely interior transition the thermal break aspect is irrelevant and the fluted top and 1/2 inch height are what decide it.
