Pemko 250DV36 – Frequently Asked Questions

1) Will the Pemko 250V threshold work on a fire-rated door opening?
Yes. The 250V Eco-V adjustable threshold is listed to UL 10C positive pressure and UL 4L10, which is what a fire-rated door assembly needs at the sill. That is the reason to spec it over a plain aluminum saddle on a rated opening in a school, hospital, or office corridor.
2) What length Pemko 250V threshold do I need for a standard 36 inch door?
The 250V comes in 36, 48, 72, 84, and 96 inch lengths. A single 36 inch leaf takes the 36 inch piece; a 72 inch piece covers a standard pair of 3-0 doors, and the 84 and 96 inch pieces cover oversized or extra-wide openings. Both the mill finish and dark bronze anodized versions are offered in all five lengths.
3) Do I still need a door sweep or door shoe if I install a 250V threshold?
No. The 4 inch wide profile carries an adjustable vinyl seal that seals the door bottom on its own, so a separate sweep or shoe is not part of the assembly. That is one less part to order and one less piece to fit on a rated door.
4) My doors bind in summer and gap in winter. Can the 250V threshold be adjusted after it is installed?
That is what the V in Eco-V threshold is for. The seal section adjusts to take up swelling and shrinking of the door and floor, so you can reset the contact on an opening that moves with the seasons instead of pulling the threshold and shimming it. Handy on a fleet of exterior doors where a few always drag.
5) Is the Pemko 250V threshold GREENGUARD certified for a school or healthcare project?
GREENGUARD Gold certified, yes. Low chemical emissions, which is what institutional and green building specs usually call for on interior finish and seal products in schools and healthcare facilities.
6) Should I use an adjustable threshold like the 250V or a fixed saddle threshold?
A fixed saddle is fine where the floor is flat and the door hangs true and stays that way. Pick the 250V adjustable Eco-V instead when the opening moves, when you are sealing exterior or high-traffic doors, or when the assembly is fire rated and you want a UL 10C listed sill that also does the sweep's job. The tradeoff is that an adjustable unit has a seal to reset over its life; a plain saddle has nothing to maintain.
7) What finishes does the Pemko 250V adjustable threshold come in?
Two: mill finish aluminum and dark bronze anodized aluminum. Mill is the plain silver aluminum that disappears under most commercial door bottoms; dark bronze anodized is the one to pick when the door hardware and frames on the building are already dark bronze and you want the sill to match.
8) What is the seal on the Pemko 250V made of, and how does the threshold mount?
The seal is Eco-V vinyl on an aluminum base. It ships pre-assembled with concealed, weather-sealed mounting screws and the adjustment mechanism built in, so the finished sill has no exposed fastener heads across the traffic path.
