Pemko K411 – Frequently Asked Questions

1) Will the Pemko K411 end plate kit fit a 1-3/4 inch door?
No. The K411 end plate kit is cut for 1-3/8 inch doors only. On commercial openings, 1-3/4 inches is the standard leaf thickness, so if that is what you are hanging, the K411 is the wrong end plate and you need the 411 series end plate kit sized for that thickness instead. Check the leaf before ordering, because the plates cap the ends of the door bottom and a thickness mismatch will not sit flush in the mortise.
2) Which Pemko automatic door bottoms does the K411 end plate kit work with?
The K411 works with Pemko 411 and STC411 automatic door bottoms, and nothing else. It is a series-specific accessory, not a universal end cap, so it will not adapt to another manufacturer's automatic door bottom or to a different Pemko series.
3) Is the Pemko K411 end plate kit approved for a fire rated door assembly?
Fire rated to UL10B and UL10C positive pressure, and BHMA certified to ANSI/BHMA A156.22. The assembly is also smoke tested to UL 1784 and NFPA 105-2013, sound tested to ASTM E90, and air infiltration tested to ASTM E-283-04, which covers the usual specification callouts on a rated or acoustic opening in a hospital, school, or government building.
4) Do I need an end plate kit at all with a 411 automatic door bottom, or is it optional?
It is an add-on. The 411 and STC411 will operate without it, but the end plates close off the ends of the case so the operating mechanism is shielded, and the mortise pocket reads as a finished detail rather than an open channel. On healthcare, education, and other high traffic openings where the door bottom gets kicked and mopped, that protection is the reason to spec it. The plunger end plate also locks the height adjustment so the setting does not rotate out of calibration after the door has been cycled for a while.
5) Do I have to order screws separately for the Pemko K411 end plates?
No, the fasteners come in the kit, and they are finished to match the door bottom case color so the heads do not stand out against the mortised edge. One install note that matters: seat them by hand. Pemko calls for no power tool tightening on these plates, because over-torquing distorts them.
6) Is the Pemko K411 surface applied or does it get mortised into the door?
Mortise applied. The K411 caps a 411 or STC411 automatic door bottom that is itself let into a pocket routed in the bottom rail, so this is not a kit you screw onto the face of an existing surface mounted sweep. If the door bottom on your opening hangs below the leaf rather than sitting inside it, you are looking at a surface mounted product and the K411 does not apply.
7) Are the Pemko K411 end plates metal or plastic?
Metal, aluminum specifically. That matters on the bottom rail of a door in a warehouse, retail entry, or multi-family corridor, where a plastic end cap is the first thing to crack when a cart or a foot catches it.
