Pemko 283D 36 – Frequently Asked Questions

1) What lengths does the Pemko 283 threshold come in, and can I get one cut for an odd elevator opening?
Three stock lengths ship ready to go: 36, 48 and 72 inches, each in mill finish aluminum or dark bronze anodized. Beyond those, the 283 is made to custom length anywhere from a 24 inch minimum to a 185 inch maximum, which is what covers offset elevator conditions and wide freight openings where a stock length would leave a gap or need field splicing.
2) How wide is the Pemko 283 threshold, and will it fit the narrow gap between an elevator sill and the lobby floor?
Width is 1-1/4 inches. That is a narrow filler profile, meant for the strip between an elevator sill and the finished floor rather than for a full door threshold with a raised stop or a saddle. Measure the actual open gap first: if it is materially wider than 1-1/4 inches you need a wider threshold section, not this one.
3) Is the Pemko 283 elevator threshold ADA compliant for a barrier-free entry?
The 283 is a barrier-free design, built to meet accessibility requirements while keeping its fire rating. At 1-1/4 inches wide it is a flat filler rather than a raised saddle, so it does not introduce the change in level a buyer normally has to detail around at an elevator entry. For a facility standardizing accessible openings, that is the point of the part.
4) Does the Pemko 283 threshold have to be screwed down, or can it be set without fasteners?
Both. The 283 is made for use with or without fasteners when it is installed together with a compatible threshold section. That matters on elevator sills where you would rather not drill into the sill angle or a finished stone floor. If it is standing alone and taking traffic, fasten it.
5) Is the Pemko 283 an elevator threshold or a regular door threshold, and when do I use each?
It is an elevator threshold, engineered specifically for offset elevator conditions where the sill and the finished floor do not line up. A regular commercial door threshold is a different animal: it carries a stop or a saddle profile, seats a door bottom or a sweep, and it works against weather and smoke at a swinging door. The 283 has none of that. Ordering it for a swinging entrance door gets you a 1-1/4 inch flat filler and no seal.
6) I am specifying elevator thresholds across a whole building. Can I standardize on the Pemko 283 for every car?
Yes, and the custom length range is why. Each elevator entrance gets its own length from 24 up to 185 inches, so a bank of passenger cars and a wider freight opening can all carry the same 283 profile, same 1-1/4 inch width, same finish. That gives a facility one part number to reorder and one fire-rated detail to document instead of a mix.
7) Is an aluminum threshold going to hold up to elevator lobby traffic and hand trucks?
The 283 is aluminum alloy, the standard base material for commercial threshold extrusions, and Pemko rates it for demanding commercial environments. Aluminum takes cart and hand truck traffic in a lobby without deforming, but it will scuff and show wear at an elevator sill over years. In a hospital or a hotel where the elevator entry is the hardest-used floor line in the building, mill finish hides that wear better than an anodized finish does.
