Pemko 273D 36 – Frequently Asked Questions

1) Will the Pemko 273 threshold work in a fire rated door opening?
Yes. The 273 half saddle threshold carries UL 10C positive pressure and UL 4L10 listings, so it can go into a fire rated assembly. It's also certified to ANSI/BHMA A156.21 for thresholds and to A117.1.
2) Is a 1/4 inch high threshold ADA compliant?
The 273 is a half saddle at 1/4 inch height by 3 inches wide, and it meets ADA requirements when butted to a 1/4 inch offset. That's the whole point of a half saddle: it picks up one side of a floor level change rather than sitting proud of the finished floor on both sides. If your floor levels are equal and you need a full saddle profile, a half saddle is the wrong shape for the opening.
3) What lengths does the Pemko 273 threshold come in, and can I get it cut to my door width?
Stocked lengths are 36 inch and 72 inch. The 273 is offered from a 24 inch minimum up to 185 inch maximum with custom cutting, and a 36 inch piece covers a standard single 36 inch door leaf while the 72 inch piece covers a pair or gets cut down on site. Aluminum this thin cuts cleanly with a miter saw and a non-ferrous blade.
4) Do screws come with the Pemko 273 threshold, or do I need to buy fasteners separately?
SMS #10 x 1 inch wood screws ship standard with the 273, so a wood-substrate install needs nothing else. If you're anchoring into concrete or into a steel sill pan, that standard screw is the wrong fastener and other fastener options are available for those substrates. Sort that out before the crew is on site with a 1 inch wood screw and a slab.
5) What finishes is the Pemko 273 half saddle threshold available in?
Two: mill finish aluminum and dark bronze anodized aluminum. Both are offered in 36 inch and 72 inch lengths. Mill is the plain silver mill aluminum that most commercial back-of-house and stair openings get; dark bronze anodized is what you specify when the door and frame package is already bronze and a bright silver sill would stand out at a main entrance.
6) Can I use the Pemko 273 threshold for a thermal break at an exterior door?
The 273 has an integrated channel that accepts thermal keys, so it can be built up for thermal performance rather than conducting straight through the aluminum. That matters on exterior openings where the sill is the cold bridge. The thermal keys are a separate item from the threshold itself.
7) Should I use a half saddle threshold or a full saddle at my door?
A half saddle like the 273 is for an offset transition, where the finished floor on one side sits lower than the other and you need to cover the edge and ramp the difference. Its 3 inch width and 1/4 inch height are sized for that. A full saddle spans the gap symmetrically and is what you want when both floors are at the same level under the door and you're covering the joint between two materials. Pick by which side of the door the level change is on.
8) I'm standardizing thresholds across a building. Is the Pemko 273 the same part at every opening?
The profile is constant: every 273 is 3 inches wide and 1/4 inch high, carries the same UL 10C positive pressure and UL 4L10 fire listings, and the same ANSI/BHMA A156.21 certification. What changes opening to opening is length and finish. So a facility can spec one threshold model across fire rated stair doors, corridor doors, and tenant entries and only vary the cut length, which keeps the attic stock down to a couple of lengths and one finish.
9) Is the Pemko 273 available in brass as well as aluminum?
The 273 is produced in aluminum or brass construction. Stocked here are the two aluminum options, mill finish and dark bronze anodized. Brass is the choice where the sill is on a public entrance being matched to brass door hardware; aluminum is the standard for back-of-house, stairwells, and high-traffic service openings.
