Pemko 175A 36 – Frequently Asked Questions

1) Is the Pemko 175 threshold ADA compliant for an accessible entrance?
The 175 Series flat saddle threshold stands 1/2 inch high, which is the maximum change in level ADA allows at a doorway, and the top is a smooth level surface rather than a ramped or grooved profile. Pemko states ADA compliance along with ANSI/BHMA A117.1. If your opening needs to come in lower than 1/2 inch you want a low-profile threshold instead, not this one.
2) Can I use the Pemko 175 saddle threshold on a fire rated door opening?
Yes. The 175 Series carries UL 10C positive pressure and UL 4L10 listings, so it can go under a fire rated door assembly. It also meets ANSI/BHMA A156.21. That is the pairing an institutional spec usually asks for: the fire listing plus the accessibility standard on the same part.
3) What length Pemko 175 threshold do I need for a 36 inch door?
Order the 36 inch length for a standard 3-0 single door. The 175 is stocked in 36, 72 and 96 inch lengths, and the series runs from a 24 inch minimum up to 185 inches. The 72 inch covers a pair of 3-0 doors; the 96 inch gives you room to cut to a frame opening that falls between sizes. Saddle thresholds are routinely cut to length on site, so buy the next length up rather than the next one down.
4) How wide is the Pemko 175 threshold, and will 4 inches cover my door frame and flooring joint?
The 175 is 4 inches wide across the full saddle with a 1/2 inch height, and it is symmetrical, so it sits half in and half out under the door leaf. Four inches gives you roughly 2 inches on each side of the door face to bridge the flooring joint between two surfaces. If your frame is deeper or the flooring transition is wider than that, you need a wider saddle.
5) Will the Pemko 175 threshold work with an automatic door bottom?
Yes. The 175 is a full saddle with a smooth, flat top and no groove or raised stop, so an automatic door bottom drops onto a continuous flat surface for a full-width seal. Pemko calls out that pairing directly. A threshold with a raised lip or a vinyl insert channel would break that seal line; the flat saddle does not.
6) Should I use a flat saddle threshold or a thermal break threshold at an exterior door?
A flat saddle like the 175 is a level transition part. It bridges two flooring surfaces under the door and gives an automatic door bottom something to seal against. It has no interior stop, no vinyl seal and no thermal break, so it does not by itself stop water or air infiltration. Use the 175 at interior openings, vestibules, and exterior doors where a separate door bottom and weatherstrip do the sealing. If the door is the weather line and you need drainage or a rain stop, specify a thermal barrier or offset threshold with a seal instead.
7) Which Pemko 175 material should I specify for a wet or high-traffic entrance?
The 175 Series is made in aluminum, brass and stainless steel. Stainless is the one to specify where cleaning chemicals, salt or standing water are in play, or in healthcare and food service. Brass is chosen where the threshold has to match brass door hardware in a lobby. Mill finish and dark bronze anodized aluminum are the stocked options and cover most commercial work, with dark bronze the usual pick to disappear against a bronze frame.
8) What fasteners come with the Pemko 175 threshold, and will they work in concrete?
Wood screws are the standard fastening on the 175, which suits a wood subfloor or a wood-framed sill. Pemko offers other fastener types for different substrates, so if you are anchoring into concrete slab, quarry tile or steel, call out the substrate when you order rather than assuming the standard pack fits it. Anchoring into slab is the most common reason a threshold order needs a fastener change.
9) I am standardizing thresholds across a building. Can I use the same Pemko 175 on every door?
For a fleet of interior and vestibule openings, yes, and that is a large part of why the 175 gets specified: one 4 inch by 1/2 inch profile, one part number, three finish and material families, and lengths from 24 to 185 inches so every leaf width is covered by the same product. The fire listing (UL 10C, UL 4L10) means the rated openings in the building take the same threshold as the unrated ones. The exception is any door that has to be the weather line or that needs to come in under 1/2 inch of level change.
10) Is the Pemko 175 threshold handed, or does orientation matter when installing it?
There is no handing and no in or out side. The 175 is symmetrical with a flat top, so it installs the same either way under the door leaf. What you do have to get right is centering it so the door closes over the middle of the 4 inch width, which puts the seal line of a door bottom on the flat and keeps the exposed edges even on both faces.
