Pemko 230A 36 – Frequently Asked Questions

1) What does the Pemko 230 carpet separator threshold actually do at a fire door opening?
The 230 is a 3 inch wide aluminum saddle that sits in the opening and holds a gap between the carpet on either side of a fire door. Two jobs at once: it keeps the carpet from butting together under the door, and it gives you a flat, solid surface to mount a door sweep or automatic door bottom against. If you're carpeting through a fire-rated opening and need a defined transition and a seal surface, that's the piece.
2) What lengths does the Pemko 230 threshold come in, and can I get one for a double door?
Stock lengths are 36, 72 and 144 inches, all in mill finish aluminum. The 230 is made in lengths from 24 inches up to 185 inches, so a full pair of doors is well inside the range. For a standard 3-0 single leaf the 36 inch piece is the direct fit; for a 6-0 pair, 72 inches runs the opening in one piece with no seam under the meeting stiles.
3) Is the Pemko 230 threshold certified to any threshold standard for a spec job?
The 230 is BHMA certified to ANSI/BHMA A156.21, the standard covering thresholds. That's the line a spec writer or an institutional buyer looks for on a submittal, and it's what lets the piece go into a government, healthcare or school project where certified hardware is called for by the drawing.
4) Can I cut a Pemko 230 threshold down to fit my opening?
Aluminum alloy extrusion, so yes, it cuts to length with a miter saw and a non-ferrous blade. Buy the next length up and trim. The catch is the screw holes: the 230 ships predrilled, and cutting the ends off will lose holes and can leave a fastener too close to a cut end. Lay the piece in the opening, mark your cut, and plan on drilling and countersinking a replacement hole near any end you shorten.
5) Does the Pemko 230 come with fasteners or do I have to order screws separately?
Screws are included. The 230 arrives predrilled and packed with #10-24 Phillips flat head machine screws, so there's no field layout or separate fastener line on the order. Machine screws, not wood screws, so the substrate needs to be tapped or anchored to take a machine thread.
6) Should I use a carpet separator like the Pemko 230 or a saddle threshold at a carpet to tile transition?
Different problems. A saddle threshold is about weather, water and level change at an exterior or bathroom opening. The 230 carpet separator is a flooring transition: 3 inches wide, it terminates carpet cleanly on both sides and holds the gap between the two pieces, which is what a fire door opening needs so the carpet isn't packed against the door bottom. If the transition is carpet to tile inside the building and you also want something to seal a sweep against, the 230 is the right family. If you're keeping water out of an exterior door, look at a weathered saddle instead.
7) Will a door sweep mount to the Pemko 230, or do I need a separate mounting piece?
No separate piece needed. The 230's flat 3 inch face is intended as the surface a door sweep or automatic door bottom seals down onto, so the threshold and the bottom seal work as one detail. You still order the sweep or automatic door bottom itself, sized to the door width, but the threshold is what gives it something solid and level to close against instead of carpet pile.
8) Will a mill finish aluminum threshold look right across a whole floor of doors?
Mill finish is the only finish the 230 is offered in, so every opening you do gets the same natural aluminum face. For a property manager standardizing corridors or a facility rolling the same detail across dozens of doors, that's an advantage: reorder in a year and the new piece matches the ones already down. Mill finish is uncoated aluminum, so it reads as a plain silver metal rather than a painted or plated finish.
