Zero thresholds are designed to stand up to the demands of heavy traffic openings and those with extreme temperature differentials. The heavy-gauge material allows you to drill and screw our thresholds directly into concrete without the difficulties common when using lighter commercial materials, such as buckling under heavy loads or loose screws.

Zero International 268A 72 – Frequently Asked Questions
1) What does the Zero 268A floor plate actually do on an adjustable threshold?
The 268A is the mating floor rest that an adjustable threshold interlocks into. It sits on the floor, and the adjustable threshold's leg seats into it so the assembly stays located and supported across the opening. It is a component, not a threshold on its own, so you order it alongside the adjustable threshold it serves.
2) Does the Zero 268A threshold plate come pre-drilled for anchors?
No. It ships without mounting holes, so you lay it out and drill on site to suit your anchor pattern into the concrete. Zero builds the section heavy enough to drill and fasten straight into concrete without the section buckling or the screws working loose, which is the usual complaint with lighter commercial stock.
3) Is the Zero 268A floor plate fire rated for a labeled opening?
Fire rated, and it carries a UL10C performance rating. It is also BHMA certified under ANSI J37360 and J37336, so it can be specified where the threshold assembly has to hold a label.
4) Does the Zero 268A meet ADA requirements for an accessible opening?
No. The 268A is not ADA accessible, so on an accessible route you need a threshold assembly rated for it rather than this interlocking rest. It is a commercial-duty part intended for heavy traffic openings and openings with a big inside-to-outside temperature swing.
5) What is the equivalent of the Zero 268A interlocking floor plate from another manufacturer?
The Pemko 61 Series interlocking J hook threshold accessory fills the same role. Both are interlocking floor members that receive an adjustable threshold rather than standing alone as the threshold itself. The materials differ: the Zero 268A is mill finish aluminum, and the Pemko 61 Series is steel construction. Length also differs, with the 268A supplied in a 72 inch piece and the Pemko 61 in 36 inches, so confirm the opening width before ordering either.
6) Can an interlocking floor plate be used on its own as the threshold at a door opening?
No. The Zero 268A is the threshold rest that the adjustable threshold interlocks into, .375 inch high and supplied without mounting holes, and the Pemko 61 Series interlocking J hook is the same kind of accessory piece rather than a finished threshold. Neither one is an ADA accessible crossing on its own; the 268A is rated ADA Accessible: No. If you need the walking surface itself, order the adjustable threshold and use the floor plate underneath it.
7) Should I use an aluminum or a steel interlocking floor plate under an adjustable threshold?
Both are sold for the same application. The Zero 268A is mill finish aluminum at .094 inch thick and .375 inch high, and it is fire rated to UL10c and BHMA certified, which matters on a labeled opening. The Pemko 61 Series is steel construction. Aluminum will not take a set the way a thinner commercial material does when drilled and screwed directly into concrete, and steel is the heavier-wearing of the two surfaces. Choose on what the rest of the threshold assembly is and on whether the opening carries a fire label.
8) What finish is the Zero 268A, and will it match my other thresholds?
Mill finish aluminum, the standard unfinished aluminum look. It matches the mill finish Zero threshold sections it interlocks with, and since most of the plate is buried under the threshold once installed, the finish is rarely the deciding factor here.
