Pemko 171BSP 48IN – Frequently Asked Questions

1) Will a Pemko 171 threshold meet ADA for an accessible entrance?
The 171 saddle threshold stands 1/2 inch high, which is the maximum change in level ADA allows at a doorway, so it works on an accessible opening as long as the floor on both sides comes up flush to it. At 5 inches wide it spans a typical frame footprint and beds flat rather than ramping. If your finished floors leave a gap under one edge, shim or fill it, because the 1/2 inch is measured from finished floor, not from the subfloor.
2) What lengths does the Pemko 171 flat saddle threshold come in?
Three stock lengths: 36 inch, 48 inch, and 72 inch. The 36 inch covers a standard 3-0 single door, 48 inch gives you cutting room on a wider opening or an out-swing with a wide frame, and 72 inch handles a pair of 3-0 doors. Aluminum cuts clean with a carbide blade, so buy the next size up and trim to your frame rather than butting two pieces together.
3) Is a flat saddle threshold the right type, or do I need a panic/thermal break or a bumper seal threshold?
A flat saddle like the 171 is a transition piece. It carries traffic across the gap between two floor surfaces and gives the door a clean line to close over. It does not by itself seal against water or air, and it has no raised stop or vinyl insert for a door bottom to seat into. For an exterior opening that needs weather sealing you want a threshold with an integral bumper or a saddle paired with a door bottom sweep. For interior openings, floor transitions, and doors where the seal is handled by the door bottom, the flat saddle is the simpler and lower profile choice.
4) Will a 1/2 inch threshold leave enough clearance under my door?
You need at least 1/2 inch of undercut from the finished floor to the bottom of the door leaf, plus a little for the door to swing without dragging. On a retrofit where the old threshold was flatter, check the door bottom before you set the new saddle. If the leaf already drags, the door has to come off and get trimmed, because the 171 is a fixed 1/2 inch height and there is no lower setting.
5) Can I cut a Pemko 171 threshold down to fit my opening?
Yes. The 171 is extruded aluminum and it is meant to be trimmed to the opening. Measure frame to frame at the floor, cut with a fine tooth carbide blade, and dress the cut edge. Order the next length up from your measurement so you are cutting rather than filling.
6) Can I use one Pemko 171 threshold across a pair of doors?
Yes, use the 72 inch length and run it as one continuous piece under both leaves. A pair of 3-0 doors is 72 inches of leaf, so measure the frame opening at the floor and trim to fit. One unbroken piece is better than two butted pieces here, because a seam in the middle of a pair sits right where the traffic crosses.
7) Is the Pemko 171 threshold durable enough for a high traffic commercial entry?
It is built for commercial duty, extruded from thick aluminum rather than a thin formed residential saddle. The black suede powder coat is a sprayed and baked finish, which holds up better to cart wheels and grit than a plain anodized surface does. Fastened down properly along its length it takes foot traffic in offices, schools, healthcare, retail, and multi-tenant buildings.
8) Does the black finish on the Pemko 171 match other black door hardware on my building?
The finish is a black suede powder coat, a low sheen textured black rather than a gloss. It reads closest to matte black hardware and to black anodized aluminum storefront. If your other openings use a bright or polished black, expect a visible difference in sheen even though the color is the same family. For a fleet of doors, set one threshold first and look at it beside the frame before you order the rest.
