Pemko 290DSSTOP 36 – Frequently Asked Questions

1) What does the Pemko 290STOP threshold stop strip actually do, and do I need a threshold with it?
The 290STOP is a stop strip, not a threshold on its own. It mounts on top of a standard flat top saddle threshold and adds the stop face plus a seal insert at the door bottom, so you get a bumper threshold built out of two parts. If the opening has no saddle down yet, you order the flat top saddle as well; the strip alone gives you nothing to fasten to.
2) How much door clearance do I need over the threshold to use the Pemko 290STOP?
Figure 1/8 inch of clearance from the top of the saddle to the door bottom. The strip itself stands 1/4 inch high and is 1-1/2 inches wide, so it sits proud of the saddle and the door has to swing over it without dragging. On a retrofit where the door was cut to sweep an existing flat saddle, check that gap before ordering, because an undercut done tight to the old saddle will bind on the new stop.
3) Is a 1/4 inch stop strip on the threshold going to be a trip hazard or fail accessibility?
The 290STOP is a barrier-free design at 1/4 inch high, meant to work with 1/4 inch saddle configurations so the assembled height stays within accessible limits. That is why it exists as a low-profile strip rather than a taller bumper: stacking a tall stop on a saddle is what pushes an opening out of compliance.
4) Which insert should I pick on the Pemko 290STOP, silicone or PemkoPrene?
Three inserts are offered and they change the model number. Silicone (290SSTOP) resists sunlight, weather, ozone, water and flame, and is self-extinguishing, so it is the pick for exterior openings and anywhere heat or UV is on the seal. PemkoPrene (290PKSTOP) is the general commercial insert. Eco-V (290VSTOP) is GREENGUARD Gold certified, bio-based, with no phthalates or heavy metals, which is what a LEED or green-building spec asks for. Silicone and PemkoPrene are the two stocked as ordered configurations.
5) Do I have to buy screws separately for the Pemko 290STOP, or is it predrilled?
It arrives predrilled and comes with #10-24 Phillips flat head machine screws cut to the right length, so nothing extra is needed to fasten the strip to the saddle. Machine screws, not wood screws, because you are threading into the aluminum saddle below.
6) Can I get the Pemko 290STOP stop strip in dark bronze to match my existing thresholds?
Two finishes: mill finish aluminum and dark bronze anodized aluminum. Both are offered in all three stocked lengths and with either the silicone or the PemkoPrene insert, so matching a bronze threshold across a building does not force you into a different insert.
7) Can I use the Pemko 290STOP to build a custom bumper threshold instead of buying a one-piece bumper saddle?
That is one of the intended uses. Pairing the 290STOP with a flat top saddle lets you assemble a bumper threshold configuration to your own width and stop location, rather than being held to a fixed one-piece bumper extrusion. It also means the seal is a serviceable part: the insert pulls and replaces without touching the saddle anchored in the floor.
8) Will an aluminum stop strip hold up in a warehouse or school entrance with heavy traffic?
The base is aluminum alloy, the same material the saddle under it is made from, and Pemko sells the 290STOP for commercial offices, schools, healthcare, retail, industrial and warehouse, multi-tenant residential and government buildings. The wear item is the insert, not the extrusion, so on a high-cycle opening you replace the seal and leave the strip in place.
