Pemko 2550A 72 – Frequently Asked Questions

1) Will the Pemko 2550 saddle threshold fit a 3 foot door opening, and what lengths does it come in?
The 2550 saddle threshold is stocked in 36, 48, 72 and 96 inch lengths. A standard 3-0 single door opening takes the 36 inch piece; the 72 and 96 inch lengths cover pairs of doors and wider frames without a splice. Aluminum, so it cuts down cleanly on site if your frame measures short of a stock length.
2) Is the Pemko 2550 threshold approved for a fire rated door opening?
Fire rated to UL10C positive pressure, cUL Listed under 4L10, and BHMA certified. That is the combination an inspector looks for on a rated opening in a hospital, school or stair enclosure, and it covers Canadian jobs through the cUL listing.
3) How high does the Pemko 2550 threshold sit, and will a wheelchair roll over it?
Half an inch high across a 10 inch wide face. That height is the reason it works on accessible routes: it stays at or under the half inch change in level that ADA allows without a bevel treatment, so carts, chairs and dollies cross it. The 10 inch width also means it spans a fair amount of the frame depth, so on a shallow jamb check your floor closer body and door swing before you cut.
4) Can I replace an existing 1/4 inch high saddle with the Pemko 2550?
Only if you can live with the height change. The 2550 stands 1/2 inch high, so swapping it in under a door hung for a 1/4 inch saddle closes up the undercut by a quarter inch and the door may drag or bind. If the door is already hung and you cannot cut the bottom, the NGP 1013 is a 1/4 inch by 10 inch mill aluminum saddle that keeps the same face width at the lower height.
5) The 10 inch saddle is too wide for my opening - what narrower threshold can I use instead?
The NGP 653 is an offset threshold measuring 1/2 inch by 5-1/2 inch in aluminum alloy, so it holds the same 1/2 inch height as the Pemko 2550 but covers a little over half the floor width. That is the option when the jamb-to-jamb run or the adjacent floor finish will not take a 10 inch plate. Note the profile change: the NGP 653 is an offset saddle, which steps between two floor levels, while the Pemko 2550 is a flat saddle type running level across the opening. If the opening is rated, the Pemko 2550 is the one carrying the UL10C positive pressure fire rating and cUL Listed 4L10 certification, and it is sold in 36, 48, 72 and 96 inch lengths to suit single and pair openings.
6) What is a fire-rated saddle threshold equivalent to the Pemko 2550 from another manufacturer?
The Cal-Royal CR3700 is a saddle threshold series carrying a 3-hour positive pressure fire rating, which puts it in the same duty class as the Pemko 2550 and its UL10C positive pressure fire rating and cUL Listed 4L10 certification. The Cal-Royal CR2000 is also a saddle threshold series with a fire rated and ADA compliant design, so it covers the same barrier-free rated opening. Both Cal-Royal series and the Pemko 2550 are saddle profiles, meaning they sit on the finished floor across the opening rather than stepping down to a lower substrate. The practical difference for a specifier is width: the Pemko 2550 is a fixed 10 inch wide by 1/2 inch high profile, sold in 36, 48, 72 and 96 inch lengths, so if the drawing calls out a 10 inch saddle the 2550 answers it directly.
7) Is the NGP 1013 the same thing as the Pemko 2550 threshold?
They are both 10 inch wide aluminum saddle thresholds with BHMA certification, but they are not the same height. The NGP 1013 is a 1/4 inch by 10 inch mill aluminum saddle, while the Pemko 2550 is 10 inch by 1/2 inch. That quarter inch matters at the door bottom: the gap the sweep or automatic door bottom has to close is set by the threshold height, so swapping a 1/2 inch saddle for a 1/4 inch one changes the undercut you are sealing against and the shim or grout bed under the plate. The other separator is rating. The Pemko 2550 carries UL10C positive pressure fire rating and cUL Listed 4L10 certification, so on a rated opening it is the one that answers the inspector.
8) My floor drops down to a lower slab on one side of the door - will the Pemko 2550 work there?
No, that opening wants an offset threshold, not a flat saddle. The NGP 653 is an offset threshold in aluminum alloy at 1/2 inch by 5-1/2 inch, and the offset profile is the one shaped to bridge two floor levels across the opening. The Pemko 2550 is a saddle type, a 10 inch wide by 1/2 inch high aluminum plate designed to sit on a single finished floor level and give a barrier-free crossing. Use the 2550 where both sides of the opening finish flush, and go to an offset profile where they do not.
9) I am standardizing thresholds across a building. Can I use the Pemko 2550 on both the rated stair doors and the ordinary corridor doors?
Yes, and that is usually the cheaper way to run a building. The 2550 is rated to UL10C positive pressure and cUL 4L10, so it satisfies the rated openings, and nothing about that rating stops it going under a non-rated corridor or office door. Ordering one model in the 36, 48, 72 and 96 inch lengths gives you a single part number for the whole facility and one profile height for every opening, which matters if you are also buying door bottoms to seat on it.
10) What do I have to specify when ordering the Pemko 2550 threshold?
Length is the only choice: 36, 48, 72 or 96 inches. Model 2550 fixes the profile at 10 inches wide by 1/2 inch high in aluminum. Anchors are a separate line item, so decide before you order whether you are shooting into concrete or screwing into a wood or steel sill, and buy fasteners to suit.
11) Which of these saddle thresholds should I quote for a 3-hour rated stair door?
The Cal-Royal CR3700 saddle series states a 3-hour positive pressure fire rating on its face, so where the submittal calls out a specific hourly rating that is the series that speaks to it directly. The Pemko 2550 is certified to UL10C positive pressure with a cUL Listed 4L10 listing, the fire test standard for positive pressure openings, along with BHMA certification, in a 10 inch by 1/2 inch aluminum saddle profile. Both are saddle profiles for a rated opening; the difference is how each states its certification, so match the wording to what the specification and the AHJ are asking for.
12) Is the Pemko 2550 threshold aluminum or brass, and will it hold up in a high traffic entrance?
Aluminum, and it is specified for commercial use rather than residential. Aluminum is what you want on an interior or protected exterior commercial opening: it does not rust, it takes foot traffic and cart wheels, and it machines easily for anchors. It is a mill finish metal threshold, so expect it to scuff and dull with traffic the way any aluminum saddle does.
