Pemko 171D 36 – Frequently Asked Questions

1) Is the Pemko 171 threshold ADA compliant for an accessible entrance?
The 171 Series flat saddle threshold stands 1/2 inch high across a 5 inch width, which is the height ceiling accessible-route rules allow at a doorway, and it is certified to ANSI/BHMA A117.1 along with A156.21 for thresholds. That combination is what lets it go under an accessible opening in a school, clinic, or municipal building without a bevel or ramp added on top of it.
2) Can I use this threshold on a fire rated door opening?
Yes. The 171 saddle threshold is BHMA Certified and carries a UL 10C positive pressure fire rating plus cUL 4L10 listing, so it can go under a rated door assembly in a commercial corridor or stairwell.
3) What screws come with a Pemko 171 threshold, and will they work on concrete?
Each piece ships with #10 x 1.5 inch wood screws. Those bite into a wood sub-sill or a wood-framed opening. For a concrete or masonry sill, the wood screws are the wrong fastener, and you'll want to order the alternate fastener option, since the 171 is supplied with other fastener choices for different substrates.
4) Should I use a flat saddle threshold or a thermal break threshold at an exterior door?
A flat saddle like the 171 is a plain transition piece. It levels the floor across the opening and gives the door bottom something to sweep against, but it has no seal or drain channel built into it. That makes it the right pick for interior openings, tenant separations, and covered exterior doors. If the door is fully exposed to weather and you need to stop wind-driven water, you want a thresholds with a raised stop or a rain drip instead, not a flat saddle. Where accessibility governs, the 171 keeps you at 1/2 inch, which a raised-stop threshold usually does not.
5) Aluminum or bronze Pemko 171 threshold, which should I order?
Three finishes: mill finish aluminum, mill finish extruded bronze (brass), and dark bronze anodized aluminum. Mill aluminum is the plain silver commercial default and the usual pick when it just has to disappear. Dark bronze anodized is aluminum with a colored anodic coating, so it matches dark bronze door hardware and frames at aluminum cost. Extruded bronze is solid brass alloy all the way through, which is what you specify when the finish needs to wear like the surrounding brass hardware in a lobby or historic entry rather than sit on the surface. All three come in every stock length.
6) Can I cut a Pemko 171 threshold down on site to fit my opening?
Yes, and it's normal practice. The 171 is an extrusion with a uniform 5 inch by 1/2 inch profile, so cutting it shorter with a miter saw and a non-ferrous blade doesn't change the section. Order the next stock length up from your frame width, 36, 42, 48, 72, or 96 inches, and trim. Predrill for the #10 screws after you've dry-fit it.
7) I'm standardizing thresholds across a building. Will the Pemko 171 match on every door?
It will, and that is the case for it on a fleet. One profile at 5 inches wide and 1/2 inch high covers every opening you put it on, in one of three finishes, at five stock lengths plus cut-to-size from 24 to 185 inches. Since it is BHMA Certified and UL 10C rated, the same part carries both your rated stairwell doors and your non-rated office doors, so you are not stocking two thresholds and matching them by eye.
