Zero International 545A36 – Frequently Asked Questions

1) Will the Zero 545 saddle threshold work for an ADA accessible entrance?
Yes. The 545 utility saddle stands only 1/4 inch high, which is under the ADA change-in-level limit, and Zero lists it as ADA compliant. At 5 inches wide it gives a broad flat crossing rather than a raised hump, so nothing needs beveling to clear it.
2) Can the Zero 545 threshold be used on a fire rated door opening?
It is fire rated up to 3 hours, so it can go under a fire door assembly rated to that level. The aluminum saddle also carries ANSI/BHMA J32100 and J32130 certification, which is the numbering an institutional spec writer will be looking for on a submittal.
3) What lengths does the Zero 545 threshold come in, and what if my opening is wider?
Three stock lengths: 36, 48, and 72 inches. A 36 inch piece covers a standard single door, 48 works for a wider single or a door with a sidelight, and the 72 inch piece covers most pairs. Aluminum extrusion at 1/4 inch thick cuts cleanly with a carbide blade, so buy the next size up and trim to the frame rather than butting two pieces in the middle of the opening.
4) Does the Zero 545 saddle come in anything other than mill aluminum?
Two finishes, both in all three lengths: A mill finish aluminum, and BK black. The black is the one to pick when the threshold sits under a dark storefront or bronze frame and you do not want a bright silver line across the opening.
5) Can I anchor a Zero 545 threshold directly into a concrete slab?
Yes, and that is what the heavy gauge extrusion is for. Zero builds these thick enough to drill and screw straight into concrete without the buckling and screws working loose that you get with lighter commercial stock. At 1/4 inch thick there is enough material at the fastener to hold under traffic.
6) Is a flat saddle threshold the right type, or do I need one with a seal or a hook?
A saddle like the 545 is a flat plate that covers the floor joint and gives the door bottom something clean to close against. It carries no gasket and no thermal break, so if you need to seal out air and water at an exterior opening you pair it with a separate door bottom or sweep. If you are replacing a threshold that interlocks with a hooked door bottom, that is a different design, the Pemko 61 Series interlocking J hook is that style.
7) Will a 5 inch wide threshold cover the gap where my old threshold was removed?
The 545 saddle is 5 inches across, which spans a typical frame footprint plus the floor break on either side, so it usually hides the scar left by a narrower unit coming out. Measure the exposed strip first, if it runs wider than 5 inches the plate will not cover it and you want a wider saddle.
8) Is the Zero 545 threshold heavy duty enough for a high traffic commercial entrance?
It is a commercial threshold, built for heavy traffic openings and for doorways with big temperature swings between inside and out. The heavy gauge aluminum is the reason, thin stock is what deforms and loosens under constant foot and cart traffic.
9) How much clearance do I need under my door to install a 1/4 inch saddle threshold?
The saddle adds 1/4 inch of height off the finished floor, so the door bottom has to clear that plus whatever sweep or door bottom you are running. On a retrofit where the old threshold was taller, the door may now swing over with extra gap, and on one that was flatter you may need to trim the door bottom.
