Pemko 170D 36 – Frequently Asked Questions

1) Will the Pemko 170 threshold work in a fire-rated door opening?
Yes. The 170 Series saddle threshold is BHMA Certified and carries a UL10C positive pressure fire rating plus cUL Listed 4L10. That covers it for fire-rated openings where the AHJ is checking the threshold along with the door and frame.
2) Is the Pemko 170 threshold ADA compliant at 1/2 inch high?
The 170 saddle stands 1/2 inch high, which is the maximum change in level ADA allows at a doorway, so it clears on height without a ramp or bevel added underneath. Anything taller than 1/2 inch would need to be beveled or ramped to stay accessible.
3) What length Pemko 170 threshold do I need for a 3-0 door?
A standard 3-0 (36 inch) single door takes the 36 inch piece, which fits the opening between jambs. Pairs of doors and wider openings go to 72 or 96 inch. The 170 is stocked in 36, 48, 72 and 96 inch, in mill finish or dark bronze anodized. Long runs get cut down on site with a miter saw and a non-ferrous blade.
4) Does a flat saddle threshold like the Pemko 170 seal out water and air?
No, and that is the main thing to settle before ordering. The 170 is a flat saddle, 1/2 inch by 4 inches, meant to cover the floor joint and give a clean transition between two flooring surfaces at an interior or protected opening. It has no vinyl seal, no bumper and no drainage lip, so it does not stop water or air on its own. For an exterior opening that has to weather, you want a thresholds with an integral seal or a separate door bottom and sweep working against the saddle.
5) What fasteners come with the Pemko 170 threshold, and will they work on a concrete floor?
It ships with #10 x 1-1/2 inch wood screws. Those are fine into a wood subfloor. On concrete you will need to swap to masonry anchors and drill the slab, so plan on ordering the alternate fastener type for that substrate rather than using what is in the box.
6) How wide is the Pemko 170 threshold and will 4 inches cover my floor joint?
The saddle is 4 inches wide across the opening, which puts roughly 2 inches on each side of the door centerline if you center it under the door. That covers a typical floor covering termination on both sides of the stop. If your tile and carpet break sits further off center, or you have a wide frame throat, measure from the joint to the door face before you commit to the 4 inch profile.
7) Will a mill finish aluminum threshold hold up in an exterior entry or a wash-down area?
The 170 is aluminum, so it will not rust, but mill finish is bare aluminum and it will dull and oxidize where it gets weather or frequent cleaning. Dark bronze anodized has a harder surface layer and hides traffic marks better, which is why it is the usual pick for a main entry or anywhere the finish is visible to tenants. Both are offered in all four lengths.
8) Do I have to cut the Pemko 170 threshold to fit, or does it come to size?
It comes in fixed stock lengths of 36, 48, 72 and 96 inches, so unless your opening matches one exactly you cut it on site. Aluminum extrusion cuts clean with a chop saw and a carbide non-ferrous blade. Measure jamb to jamb at the floor, not the door width, since the frame throat eats into the opening.
9) Can one Pemko 170 threshold run under a pair of doors?
Yes. A flat saddle has no center break or mullion interruption, so a single continuous piece runs the full width of a pair. A pair of 3-0 doors is a 72 inch opening, which the 72 inch length covers; wider pairs take the 96 inch and get trimmed.
10) Can I use the Pemko 170 saddle threshold in an apartment or residential unit door?
You can, and it is common in multi-tenant residential corridors, but the 170 is built as a commercial threshold, not a light residential one. The heavier 1/2 by 4 inch aluminum extrusion and the UL10C rating are what makes it right for a rated corridor door in an apartment building. For a plain interior closet or bath transition in a house it is more threshold than the opening needs.
11) What does the fluted top on the Pemko 170 threshold do?
The fluting is a ribbed pattern milled into the walking surface. It breaks up the smooth aluminum so the saddle is less slick underfoot when wet, which matters at an entry or anywhere floors get mopped. It also disguises scuffing better than a plain flat top over years of traffic.
