Pemko 2221AV-36 – Frequently Asked Questions

1) Will the Pemko 2221 door shoe work on a 36 inch hollow metal door?
That is exactly what the 2221 is set up for. It comes in a 36 inch length and Pemko lists it for architectural doors and hollow metal doors. The shoe wraps the bottom edge of the door in a U shape, so it mounts to the door itself rather than the threshold, and it travels with the door. If your opening is a 3-0 door, the 36 inch length matches the leaf with no cutting; on a narrower leaf, aluminum shoe stock like this is cut to length on site.
2) Is the Pemko 2221 door shoe fire rated, and can I use it on a labeled opening?
The 2221 carries a UL 10C positive pressure fire rating and is cUL Listed under 4L10, so it is a rated-opening product. It is also smoke tested to UL 1784 and air infiltration tested, and it is BHMA certified. For a healthcare or institutional facility standardizing on labeled hollow metal doors, that combination of ratings on one bottom seal is the reason to spec it.
3) Should I use a door shoe with a rain drip or a plain door sweep on an exterior door?
A door shoe and a sweep solve different halves of the problem. The 2221 is a U-shaped shoe: the aluminum channel caps the bottom edge of the door on both faces and holds the seal insert underneath, and the integral rain drip throws water off the face of the door before it reaches the sill. A surface sweep only fastens to one face and does nothing about water running down the door. For an exterior hollow metal opening taking weather, the shoe with the drip is the right call. For an interior door where you only need to close a gap over the floor, a sweep is simpler and cheaper to install.
4) How much room does the Pemko 2221 door shoe need under the door?
The shoe profile measures 1-3/4 by 1-5/8 inches. The 1-3/4 inch figure is the width the U-channel needs to wrap a standard commercial door thickness, and the 1-5/8 inch is the height of the profile. Check the undercut on your leaf before ordering: if the door was hung tight to the floor or to an existing threshold, a shoe of this depth may need the door bottom trimmed, and on a rated door that is not something you do without checking the label.
5) What else does ZenSupply carry if the Pemko 2221 is not the right door shoe for my opening?
Three other aluminum door shoes cover different needs. The Cal-Royal DS-403 is an aluminum shoe with a vinyl insert, the straightforward option when GREENGUARD certification is not being asked for. The NGP 112 uses a neoprene seal in an aluminum alloy body and is rated for a temperature range of -20 F to 200 F, which is the one to look at for freezer vestibules, boiler rooms, or unconditioned exterior openings. The NGP 12T pairs a mill aluminum base with thermoplastic vinyl fins. The Pemko 2221 is the one to keep when the job needs the UL 10C fire rating and the GREENGUARD Gold insert.
6) What is the closest alternative to the Pemko 2221 door shoe if a vinyl insert is acceptable instead of Eco-V?
The Pemko 2221 is a U-shaped door shoe on an aluminum substrate carrying an Eco-V insert. The Cal-Royal DS-403 is an aluminum door shoe with a vinyl insert, so it covers the same door bottom function on the same base material with a conventional vinyl seal rather than the Eco-V material. If a project is pursuing GREENGUARD Gold credit, the 2221 is the one carrying that certification.
7) Which door shoe should be used on an opening that sees temperature extremes rather than a conditioned interior?
The NGP 112 is a neoprene door shoe with aluminum alloy construction rated over a temperature range of -20 F to 200 F, which is the spec to work from when an opening swings between hot and cold extremes. The Pemko 2221 uses an Eco-V insert on an aluminum substrate and is the choice where indoor air quality certification and fire and smoke performance drive the selection.
8) For a fire rated hollow metal opening, which door shoe carries the listings an inspector will ask about?
The Pemko 2221 is the one to specify on that opening: it is fire rated UL10C positive pressure, smoke tested UL1784, cUL listed 4L10, BHMA certified, air infiltration tested and sound tested to ASTM E90, and it is intended for architectural and hollow metal doors. Among the aluminum door shoe alternatives, the Cal-Royal DS-403 and the NGP 12T are described by their base and insert materials rather than by fire and smoke listings.
9) What is the Eco-V insert in the Pemko 2221, and is it better than vinyl?
Eco-V is Pemko's bio-based seal material, used in place of standard vinyl. Its plasticizers come from renewable carbon sources and the stabilizers are organic and zinc free, with no phthalates and no heavy metals. It is GREENGUARD Gold certified for low emissions, which is what gets it accepted on projects chasing green building credits and in schools and healthcare where indoor air quality is scored. Practically, it has good resistance to adhesives and most mild cleaning solutions, but limited UV and weather resistance, so it holds up better on protected exterior openings than on a fully sun-exposed south elevation.
10) Can I replace an existing Pemko door shoe with the 2221 without changing the door prep?
A U-shaped shoe of this style fastens through the face of the door on both sides, so swapping one wrap-around shoe for another is usually a matter of pulling the old one and mounting the 2221 in the same position. Two things decide it: the profile of the 2221 measures 1-3/4 by 1-5/8 inches, so the existing undercut has to accommodate that height, and the 1-3/4 inch channel width has to match your door thickness. If what is on the door now is a single-face surface sweep rather than a wrap shoe, you are drilling a new pattern on the opposite face.
11) Will one Pemko 2221 door shoe cover a pair of doors?
No. The 2221 is a 36 inch shoe sized for one leaf. A pair of doors needs one shoe per leaf, so order two for a 6-0 pair of 3-0 leaves. The shoe seals the gap between the door bottom and the floor or threshold only; the meeting stile between the two leaves is a separate astragal, and the head and jambs need their own perimeter gasketing.
12) What is the difference between a vinyl insert door shoe and a neoprene one when standardizing door bottoms across a building?
The Cal-Royal DS-403 and the NGP 12T both seal with vinyl, the DS-403 as an insert in an aluminum shoe and the 12T as vinyl fins on a mill aluminum base. The NGP 112 uses neoprene on aluminum alloy construction with a stated -20 F to 200 F range. The Pemko 2221 runs an Eco-V insert on aluminum. All four are aluminum-based door bottom shoes, so the practical sorting question across a fleet of openings is which sealing material suits each door.
13) Which door shoe is the plain commercial option when GREENGUARD certification is not part of the project requirements?
The Cal-Royal DS-403 is an aluminum door shoe with a vinyl insert and is the straightforward door bottom shoe where no indoor air quality certification is being chased. The Pemko 2221 carries GREENGUARD Gold certification along with its Eco-V insert, which is what earns it a place on projects tracking emissions criteria.
14) Does the Pemko 2221 door shoe help with sound transfer between rooms?
It was sound tested to ASTM E90, and it is also air infiltration tested. The bottom of a door is usually the largest single leak path in an opening, so sealing it with a full-wrap shoe does more for both sound and air than any other single gasket. That said, a bottom seal alone will not get an opening to an STC target; it needs perimeter gasketing on the head and jambs to work as a system.
15) What finish does the Pemko 2221 door shoe come in?
Mill finish aluminum, which is the raw uncoated aluminum look, and it is the only finish this shoe is built in. On hollow metal openings that is normally fine since the shoe sits at the floor line and out of sightline. If the specification calls for a dark bronze or clear anodized bottom to match other perimeter gasketing on the job, mill finish will not blend and you want a different shoe.
16) Is the Pemko 2221 door shoe rated for commercial traffic, or is it a residential part?
Strictly a commercial part. Pemko lists it as commercial with an aluminum substrate and BHMA certification, and it is meant for architectural and hollow metal doors, the kind of opening found in offices, schools, hospitals, retail, warehouses, and municipal buildings. For a property manager standardizing bottom seals across a building of hollow metal exterior doors, one model in one length covers every 3-0 leaf.
