Pemko 173A 36 – Frequently Asked Questions

1) Will the Pemko 173 threshold meet ADA requirements for a barrier-free opening?
At 3/16 inch high, the 173 flat saddle is well under the 1/2 inch maximum change in level ADA allows at a doorway, and Pemko lists it as ADA compliant to ANSI/BHMA A117.1. That low profile is the whole point of a flat saddle: no bevel to negotiate, nothing for a wheelchair caster or a cart to catch on. If you are replacing a taller thermal-break or panic threshold in an accessible route, this is the shape you want.
2) Can I use a Pemko 173 saddle threshold in a fire rated door opening?
Yes. The 173 carries UL 10C positive pressure and UL 4L10 listings, so it can go under a fire rated assembly. Follow the opening's listed hardware schedule for fastener type and substrate.
3) Is a 2-1/4 inch flat saddle wide enough, or do I need a wider threshold?
The 173 is 2-1/4 inches wide, which suits an interior or protected opening where the saddle only has to cover the joint between two floor finishes under a single door. It is not a weather threshold: there is no rise, no stop leg and no drain slope, so on an exposed exterior door taking wind-driven rain you want a wider panic or thermal break threshold with a raised leg instead. Pair the 173 with an automatic door bottom when you do need a seal, since the flat top gives the door bottom an even surface to drop onto.
4) Does a Pemko 173 threshold come with screws, or do I have to buy fasteners separately?
SMS #10 x 1 inch wood screws ship with the threshold. Those are right for a wood subfloor. Going into concrete, tile or steel, plan on the alternate fastener option for your substrate, since a 3/16 inch thick saddle gives you very little material for a countersunk head to sit in and the wrong anchor will stand proud of the walking surface.
5) What is the difference between mill finish and dark bronze anodized on the Pemko 173?
Both are aluminum. Mill finish is the raw extrusion, a plain silver that blends with aluminum frames and hollow metal, and it is the usual choice where the threshold is not meant to be noticed. Dark bronze anodized is a colored anodic coating over the same aluminum, matched to dark bronze frames and storefront. Anodizing also puts a harder surface on the aluminum, which matters on a saddle that gets walked across all day. Both are offered in 36, 42 and 72 inch lengths.
6) I have to standardize thresholds across a building. Will the Pemko 173 work on every door type?
For interior openings across a facility, one 173 profile plus the right cut length covers most of them, which is what makes it easy to standardize on: same 3/16 by 2-1/4 inch section on every door, same finish, only the length changes. Where it stops working is exterior openings needing a weather seal and openings where the floor levels differ by more than the saddle can bridge. A flat saddle covers a joint, it does not ramp between two heights, so a floor transition with any real step needs a beveled or offset threshold instead.
7) Can I install a Pemko 173 threshold over an existing floor without re-prepping the door?
Usually yes, and that is the argument for a 3/16 inch saddle over a taller one. It only takes 3/16 inch out of the undercut, so on a door already hung with a normal gap at the bottom you can lay it across the opening without trimming the door. Check the actual gap first if the door has a sweep or an automatic door bottom on it, since those need their own clearance on top of the saddle height.
8) Is the Pemko 173 saddle rated for commercial traffic or is it a residential threshold?
It is a commercial threshold, used in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings. Aluminum construction with a smooth flat top, which is also why it sheds mud, ice and snow instead of packing it into a groove the way a ribbed threshold does.
