Pemko 172D 36 – Frequently Asked Questions

1) Is the Pemko 172 threshold ADA compliant for a barrier-free opening?
At 1/2 inch high, the 172 saddle threshold sits at the maximum rise ADA allows for a threshold at a doorway, and it is certified to ANSI/BHMA A156.21 and A117.1. The 6 inch width gives you the full bearing surface across the opening. If the finished floor on either side already steps up, measure the total rise from finish floor to the top of the saddle, not just the threshold height.
2) Can I use a Pemko 172 saddle threshold on a fire rated door assembly?
Yes. The 172 is BHMA Certified, Fire Rated to UL10C positive pressure, and cUL Listed 4L10, so it can go under a fire rated door assembly. That is the rating an inspector looks for on a labeled opening in a hospital, school, or stairwell.
3) What lengths does the Pemko 172 threshold come in, and what if my opening is wider?
Stock lengths are 36, 42, and 72 inches. Pemko produces the 172 in lengths from 24 inches up to a 185 inch maximum, so wider or paired openings are covered by ordering a longer piece. Aluminum saddle thresholds cut cleanly with a miter saw and a non-ferrous blade, so buying the next size up and trimming to the frame is normal practice.
4) What finishes is the Pemko 172 threshold available in?
Three: mill finish aluminum, dark bronze anodized aluminum, and black suede powder coat. All three are offered in each of the 36, 42, and 72 inch lengths. Mill is the plain aluminum most commercial openings get; dark bronze anodized matches bronze frames and hardware; black suede powder coat is the one to pick when the storefront or entry hardware is black.
5) Do I need to buy fasteners separately for a Pemko 172 threshold?
No. Standard #10 x 1-1/2 inch wood screws ship with the 172. Those are for wood substrate. If you are anchoring into concrete, tile, or a raised metal sill, plan on sleeve anchors or masonry fasteners in the pre-drilled holes instead, since the included wood screws will not hold in those.
6) Is a flat saddle threshold the right type, or do I need one with a weatherstrip or thermal break?
A flat saddle like the 172 is a transition piece: it covers the floor joint under the door and gives a clean, low bearing surface. It has no vinyl seal insert and no thermal break, so it does not weather-seal an exterior opening on its own. Use it on interior openings, vestibule and corridor doors, and on exterior doors where a separate door bottom or sweep does the sealing. If the opening needs the threshold itself to stop water and air, you want a saddle with an integral bumper seal or an interlocking threshold instead.
7) I'm standardizing thresholds across a building. Can I use the same 172 on every door?
Yes, and that is the usual reason to spec it. The 172 is a single 1/2 inch by 6 inch profile in three lengths and three finishes, and it carries the fire rating, so one part covers both your labeled and non-labeled openings. Pick one finish, order 36 inch for single doors, 42 inch for wider leaves, and 72 inch for pairs or to cut down. The exception is any opening that needs a weather seal built into the threshold, which this flat profile does not provide.
8) Will an aluminum threshold hold up in a high-traffic commercial entry?
The 172 is extruded aluminum and rated Commercial, not residential. Aluminum is the standard substrate for saddle thresholds in offices, schools, healthcare, retail, and warehouse openings; it takes cart and foot traffic without corroding. Mill and anodized finishes wear to bare metal at the traffic line over time, which is cosmetic. On a heavily used entry the powder coat will show scuffing sooner than the anodized.
