Pemko 158A 40IN – Frequently Asked Questions

1) Will the Pemko 158 threshold work where my tile floor sits higher than the carpet on the other side of the door?
That is exactly the condition the 158 offset saddle is cut for. It is an offset threshold built to bridge a 1/4 inch height change between two floor surfaces, tile to carpet being the usual case. If your height difference is materially more than 1/4 inch, this profile won't sit flat on both sides and you want a different offset height.
2) What are the actual dimensions of the Pemko 158 aluminum saddle threshold?
The 158 saddle measures 5-1/2 inches wide and 1/2 inch high, in a 40 inch length. The 5-1/2 inch width is the number that usually decides the job: it needs that much clear floor under the opening, which on a typical residential or light commercial jamb means the saddle runs past the door stop on both faces.
3) What fasteners do I need to install a Pemko 158 threshold, and are they included?
The 158 is set up for #10 x 1-1/2 inch wood screws, which is what you want over a wood subfloor or a wood sill. Alternative fasteners are offered for other substrates, so if you are anchoring into concrete or a slab, order those separately rather than trying to drive wood screws into masonry.
4) Is the Pemko 158 threshold fire rated?
Yes, the 158 is a fire-rated aluminum saddle, which is what lets it go under a rated opening in a corridor or stairwell rather than only in a non-rated interior doorway.
5) Should I use an offset saddle like the Pemko 158 or a flat saddle threshold?
Pick by what the two floors do. A flat saddle assumes both sides finish at the same height and just covers the joint. The 158 is offset, meaning one side sits 1/4 inch higher than the other by design, so it is the one to use when carpet meets tile or a finished floor meets a thinner one. Put an offset saddle on a level joint and you create the trip edge you were trying to remove.
6) What finish does the Pemko 158 saddle threshold come in?
Mill finish aluminum, the natural unpainted extrusion color. If you are standardizing a floor of openings, that is the finish every piece will match, so mixing it with an anodized or bronze saddle elsewhere in the same corridor will read as a difference.
7) Is the Pemko 158 threshold meant for commercial buildings or houses?
Commercial duty. The 158 is specified for commercial openings, offices, retail, healthcare, schools, hotels and multi-tenant residential, and it carries fire rating for those code conditions. It installs fine in a house, it is simply built heavier than a residential-grade saddle needs to be.
