Pemko 218D 36 – Frequently Asked Questions

1) Will the Pemko 218 threshold work on a fire rated door opening?
Yes. The 218 saddle threshold is fire rated, UL 10C positive pressure tested, and cUL Listed under 4L10, so it can go under a fire rated door assembly. It's also GREENGUARD Gold certified, which matters on schools, healthcare and other jobs with indoor air quality requirements in the spec.
2) How wide and how tall is the Pemko 218 saddle threshold?
The 218 is 3-1/2 inches wide with a 5/8 inch height. That 5/8 inch rise is what sets your undercut: the door bottom has to clear the high point of the saddle, so plan the door bottom and any shoe or sweep around it. The 3-1/2 inch width covers a standard residential sill without running past the jamb line.
3) Does the Pemko 218 threshold seal the door bottom by itself?
No. The 218 is a saddle only, it gives the flat sealing surface and the transition. To actually close the gap you pair it with a door bottom shoe or a sweep on the door, and the two together make the seal. Order the bottom seal separately.
4) I'm standardizing thresholds across apartment unit entries. Can I use the same Pemko 218 on all of them?
That's what it's built for. The 218 is a residential saddle for pre-hung openings, offered in one profile at 3-1/2 by 5/8 inches, so every unit gets the same rise and the same door undercut. Pick one finish, mill or dark bronze, across the property and order 36 inch for standard single unit doors. Because it's fire rated and UL 10C positive pressure tested, the same part also works on rated corridor doors, so you don't need a second SKU for those openings.
5) What lengths and finishes does the Pemko 218 threshold come in?
Stock lengths are 36, 48 and 72 inches, each offered in mill finish aluminum or dark bronze anodized aluminum. A 36 inch piece covers a standard 3-0 single door; 72 inch handles a pair of doors or a door with a sidelite. Mill finish is the plain silver aluminum, dark bronze is the darker anodized coating for bronze or dark trim packages.
6) Do I need to buy screws or drill the Pemko 218 threshold before installing it?
Neither. The 218 arrives predrilled with WS #10 x 1.5 inch machine screws included, so it goes down without extra hardware. If you're anchoring into concrete rather than a wood sill you'll want your own anchors for that substrate.
7) Can I cut a Pemko 218 aluminum threshold down to fit my opening?
Yes, it's extruded aluminum and cuts clean with a miter saw and a non-ferrous blade. Buy the next length up from your opening width and trim to fit between the jambs. Cutting it does mean you may lose a predrilled hole or two at the cut end, so plan the anchor spacing before you cut.
8) Is the Pemko 218 a commercial threshold or a residential one?
Pemko lists the 218 as residential, and the 3-1/2 inch by 5/8 inch saddle profile is sized for pre-hung entry openings rather than heavy commercial traffic. It shows up regularly in apartment and multi-family unit entries. For a high-traffic commercial entrance, look at a heavier commercial threshold profile instead.
9) Will a dark bronze anodized threshold hold up outdoors?
The 218 is extruded aluminum, anodized in the dark bronze version, so it takes weather exposure at an entry without rusting the way a steel part would. Anodizing is a surface treatment, so expect wear at the walk line over time on any threshold in a busy doorway.
