Pemko 2052D36 – Frequently Asked Questions

1) Will the Pemko 2052 threshold work where tile or thick carpet runs right up to the door?
That is what the 2052 is built for. The interior support leg flushes with the interior jamb so the flooring can abut the threshold squarely, which is why it suits tall terra cotta, plush carpet, and stone paver entries. At 5/8 inch high and 3-5/8 inches wide, the interior side sits high enough to meet those thicker floor build-ups instead of leaving a lip.
2) What length Pemko 2052 threshold do I need for a 36 inch door opening?
The 2052 is stocked in 36 inch and 72 inch lengths. A 36 inch cut covers a standard single 3-0 opening measured jamb to jamb, and the 72 inch piece covers a pair of 3-0 doors or gets cut down on site. Pemko makes this profile from 24 inches up to 185 inches, so odd openings are handled by cutting the longer stock piece.
3) Is the Pemko 2052 threshold fire rated for a labeled opening?
The 2052 aluminum threshold is UL 10C positive pressure listed and UL 4L10 listed, so it can go under a fire rated opening where the door assembly calls for a listed threshold.
4) Does the Pemko 2052 threshold come with screws, or do I have to buy fasteners separately?
WS #10 x 1.5 inch fasteners go with the 2052. Those are the wood screw size Pemko specifies for it, so a standard wood jamb and sill install needs nothing extra. Into concrete or masonry you supply your own anchors sized to the same #10 hole.
5) Is a squareback threshold like the Pemko 2052 the right choice, or do I need a saddle style?
A squareback has a vertical face on the interior side rather than sloping both ways like a saddle. That vertical face is the point: the support leg behind it lands flush with the interior jamb so finished flooring can butt straight into it. On the exterior side the 2052 still ramps, with a gently sloping ribbed surface that sheds rain and keeps the transition walkable. If your floor on both sides is thin and level, a saddle profile that ramps two ways is the simpler part. If one side has tile, pavers, or heavy carpet stacking up, the squareback is what closes that height difference cleanly.
6) Will the Pemko 2052 threshold trip people or fail an accessibility walk-through?
The exterior side is a gently sloping ribbed ramp specifically to keep it from being a trip edge, and overall height is 5/8 inch. The interior side is square, so it is only flush if the finished flooring is brought up to meet the support leg the way the profile intends. Install it with the floor short of that leg and you have created the step you were trying to avoid.
7) Is the Pemko 2052 threshold GREENGUARD certified for a school or healthcare project?
GREENGUARD Gold Certified, which is the low chemical emission tier that gets specified on schools, healthcare, and other projects chasing indoor air quality credits. The 2052 is aluminum, so there is no coating or sealant off-gassing to manage on install.
8) How wide is the Pemko 2052 threshold, and will it cover my sill?
3-5/8 inches wide by 5/8 inch high. That width lands under a standard 1-3/4 inch commercial door with room on both sides of the door face, so it covers the sill under the door and carries out past the stop line. If your sill is deeper than 3-5/8 inches you will see bare sill outboard of the threshold and want a wider profile instead.
9) What finishes does the Pemko 2052 squareback threshold come in?
Two: mill finish aluminum and dark bronze anodized aluminum. Mill is the raw silver aluminum that disappears against most aluminum frames; dark bronze anodized matches bronze storefront and dark hardware, and the anodizing is a harder surface than bare mill for openings that get scuffed. Both are offered in the 36 inch and 72 inch lengths.
10) Will an aluminum threshold hold up under heavy foot traffic in a commercial entry?
The 2052 is aluminum, which resists corrosion at an exterior sill where water sits, and it carries a center support leg in addition to the interior leg. That center leg is there so the walking surface does not deflect when the threshold spans an uneven or hollow sill. For a high-traffic entrance it matters that the threshold is bedded and fastened along its full length; the legs only do their job when there is solid bearing under them.
