Pemko 412CRL-30 – Frequently Asked Questions

1) Will a Pemko 412 automatic door bottom work on a fire rated door?
Yes. The Pemko 412 automatic door bottom is fire rated to UL10C positive pressure and smoke tested to UL1784, so it can go on a rated opening where the smoke and fire seal has to hold up under test. It is also air infiltration tested to ASTM E-283-04 (2012) and sound tested to ASTM E90-2009, which is what gets it onto acoustic and air-leakage specs for offices and healthcare corridors.
2) How much clearance under the door does the Pemko 412 need, and does it mount on the door face?
The 412 is a surface mounted unit that screws to the face of the door at the bottom rail, so it hangs below the door rather than sitting in a routed pocket. The aluminum casing measures H: 2 inches, W: 9/16 inches, so plan on the housing occupying roughly two inches of door face height and projecting 9/16 of an inch off the face. Because it is surface applied, no mortise pocket has to be cut, which is why it is the usual pick for retrofitting an existing door.
3) Do I need to specify handing when ordering a Pemko 412 door bottom?
Yes, the 412 is a handed automatic door bottom. The plunger that trips the seal sits at the hinge or strike end depending on hand, so a left hand unit will not operate correctly on a right hand door. Confirm the door swing before you order, and if you are doing a floor of openings, count lefts and rights separately.
4) Should I use an automatic door bottom or just a door sweep?
A sweep drags on the floor the whole time the door moves. An automatic door bottom like the Pemko 412 stays retracted while the door swings and drops the seal only when the door closes against the stop, which is what you want over carpet, over a finished floor you do not want scuffed, or where drag would fight a closer set for accessible opening force. The 412 seals against light, sound, smoke and fire when closed. If the opening has a big undercut and nobody cares about drag, a plain sweep is simpler and cheaper to install.
5) Does the Pemko 412 come with mounting screws or do I have to buy them separately?
Mounting screws and installation instructions ship with the 412. Nothing else is required to attach it to the door face. What is not included is the mating threshold or saddle it seals down onto, so if the opening does not already have a flat surface at the sill, that gets ordered separately.
6) Is the Pemko 412 suitable for a school or hospital where indoor air quality is specified?
It is GREENGUARD Gold certified, which is the chemical emissions standard schools and healthcare facilities most often write into their specs. Combined with the UL1784 smoke test and UL10C fire rating, the 412 covers both the life safety and the IAQ line items on a typical institutional door hardware schedule. It is a commercial rated product intended for architectural doors.
7) Can I cut a Pemko 412 automatic door bottom down to fit a narrower door?
Yes, the 412 is meant to be cut to length for the opening. Order the next size up from your door width out of the 30, 36, 42 and 48 inch options and trim the aluminum housing and insert to suit. That is how one part number covers a building full of slightly different leaf widths.
8) What finishes does the Pemko 412 automatic door bottom come in, and will it match my other door hardware?
Two anodized aluminum finishes: clear anodized and dark bronze anodized. Clear anodized reads as a natural silver aluminum and blends with aluminum storefront and most brushed hardware. Dark bronze anodized matches dark bronze storefront and dark finish exit devices. Both are available in all four lengths and with either insert, so finish does not restrict your other choices.
9) Will an automatic door bottom help with sound transfer between a corridor and an office?
The gap under the door is usually the biggest acoustic leak in an opening, and the Pemko 412 closes it: it is sound tested to ASTM E90-2009 and air infiltration tested to ASTM E-283-04 (2012). The EPDM insert compresses against the floor or threshold when the door latches. For it to do anything for you the rest of the opening has to be sealed too, since head and jamb gaps will leak just as readily.
10) Will the Pemko 412 hold up on an exterior door?
The housing is extruded aluminum in an anodized finish and the seal is EPDM, a rubber that stands up to weather and UV better than most, so the 412 is built for that exposure. It is air infiltration tested to ASTM E-283-04 (2012), which is the test that matters for stopping drafts at a perimeter door. Note it seals only when the door is closed, so it does nothing for a door propped open.
