Pemko 345APK-36 – Frequently Asked Questions

1) Will the Pemko 345 door bottom sweep work on a fire rated door?
The 345 Series sweep is BHMA Certified and Fire Rated to UL10C, with smoke testing to UL1784 and an Underwriters Laboratory 4L10 listing. That combination is what a fire door assembly needs from a bottom seal, and it is also what an inspector on a healthcare or education facility will look for. It is GREENGUARD Gold Certified as well, which matters on projects chasing indoor air quality credits.
2) What size door does the Pemko 345 Series 36 inch sweep fit?
It comes factory cut at 36 inches, so it covers a standard 3-0 door leaf. The extrusion body is 9/16 inch wide by 1-1/2 inch high, which is the projection you need to clear at the bottom rail and off the face of the door. On a narrower leaf, aluminum extrusion sweeps like this are cut down to the door width on site; on anything wider than 36 inches this length will not reach.
3) Is the Pemko 345 sweep surface mounted or does it need door prep?
Surface mounted. It is a surface plate sweep that screws to the face of the door bottom rail, so there is no mortising, no routing, and no bottom rail machining. That is the difference between this and an automatic door bottom that drops a seal from inside a mortised channel. For a property manager retrofitting existing openings, surface mounting means the door stays in the frame and the work is done with a drill and a level.
4) Should I use a door sweep with a rain drip or a plain sweep on an exterior door?
Pick the rain drip version on any opening that sees weather. The 345 Series has the drip built into the extrusion, so water running down the face of the door is thrown clear of the threshold instead of tracking under it. On an interior opening, an office corridor or a stair door, the drip does nothing for you and adds projection off the door face; a plain sweep is the cleaner choice there.
5) Will the PemkoPrene insert hold up to hospital cleaning chemicals and disinfectants?
That is exactly what PemkoPrene is specified for. The gray insert is a thermoplastic rubber with stated resistance to cleaning fluids and disinfectants, which is why it turns up on healthcare, food service, and institutional openings that get wiped down daily. A vinyl insert degrades faster under that routine. It also runs at low operating force, so the door still closes and latches normally with the seal compressed.
6) Does a door bottom sweep replace the threshold, or do I need both?
You need both. The sweep seals the gap between the door bottom and whatever is under it; the threshold is the piece fixed to the floor that the sweep seals against. With the 345 Series at 1-1/2 inch high and 9/16 inch of projection, mount it so the insert bears on the threshold or floor without binding the swing. On a full weatherseal job the sweep handles the bottom and perimeter gasketing handles the head and jambs.
7) Can I use the Pemko 345 sweep for smoke sealing on a smoke barrier door?
It is tested to UL1784 for air leakage, which is the smoke test referenced for smoke and draft control assemblies, and it carries the UL10C fire rating alongside it. It is also compliant with ANSI/BHMA A156.22, the standard for door gasketing and edge seals, so it can be written into a spec that calls out A156.22 gasketing on a smoke barrier opening.
8) What finish and material is the Pemko 345 Series sweep?
Mill finish aluminum extrusion with a gray PemkoPrene insert. Mill finish is the raw uncoated aluminum, so it reads silver and will match other mill finish aluminum weatherstripping and thresholds on the same opening rather than an anodized dark bronze or a painted frame. The insert is offered in black or gray.
