Zero International 103 Aluminum Offset Threshold with ADA Compliant Design

The Zero International 103 is a transitional offset threshold engineered to eliminate the tripping hazard created by irregular floor surfaces where flooring materials such as tile or carpet meet at a doorway. Measuring 7" wide, this threshold features a 1/4" offset height, a 1/4" upper saddle height, and a total height of 1/2", providing a smooth, low-profile transition between differing floor levels. Available in Aluminum Clear Anodized and Dark Bronze finishes, it is custom cut to size up to 104", with larger sizes available through the manufacturer's office. This threshold meets ADA and Wheelchair Compliance requirements, making it suited for commercial applications where accessibility is required.

Key Features

  • Width: 7" wide for standard commercial doorway applications.
  • Offset Height: 1/4" offset height creates a gradual transition between uneven flooring surfaces.
  • Upper Saddle Height: 1/4" upper saddle height contributes to the low-profile total height of 1/2".
  • Custom Length Options: Custom cut to size up to 104"; larger sizes available by contacting the manufacturer's office directly.
  • Finish Options: Aluminum Clear Anodized or Dark Bronze.
  • Drilling Options: Supplied undrilled by default; drilling can be provided when a template is submitted to the manufacturer's office.
  • Non-Stick Epoxy Abrasive Option: Optional abrasives bonded into the grooves deliver a coefficient of friction of 1.02 dry and 0.98 wet, supporting compliance with ADA, OSHA, and most local building code slip-resistance requirements.

Why Zero International 103?

The Zero International 103 offset threshold delivers an ADA-compliant 1/2" total height profile that smooths the transition between differing floor surfaces at commercial doorways. The optional non-stick epoxy abrasive tread adds measurable slip resistance for code compliance in high-traffic environments. Available in Aluminum Clear Anodized and Dark Bronze, custom cut to 104", this threshold is a reliable specification for architects and contractors sourcing commercial door trim components.

Zero International 103A-36 – Frequently Asked Questions

1) Will the Zero 103 threshold work where tile meets carpet at a doorway with different floor heights?
That is exactly the transition the Zero 103 is built for. It is an offset threshold, meaning one side sits a 1/4 inch step above the other so it bridges two floor levels rather than sitting flat on one. Total height is 1/2 inch, with a 1/4 inch offset and a 1/4 inch upper saddle, and the piece is 7 inches wide so it spans a reasonable amount of both floor materials. If both sides of your opening are at the same level, an offset profile is the wrong shape and a flat saddle threshold is what you want.
2) Is the Zero 103 offset threshold ADA compliant for a wheelchair-accessible entry?
The 103 meets ADA / wheelchair compliance. The reason is the profile: 1/2 inch total height with the rise split into a 1/4 inch offset and a 1/4 inch upper saddle, so no single vertical step is more than a quarter inch. Slip resistance is a separate decision. Ordered with the optional non-stick epoxy abrasive bonded into the grooves, the surface runs a coefficient of friction of 1.02 dry and 0.98 wet, which covers ADA, OSHA and most local building code slip requirements. Without the abrasive you get the plain aluminum surface.
3) What lengths and finishes does the Zero 103 threshold come in, and can I get it cut to my opening?
Two stock lengths, 36 inch and 72 inch, in either Aluminum Clear Anodized or Dark Bronze, and all four combinations are orderable. Beyond stock, the 103 is custom cut to size up to 104 inches; anything longer than that goes through Zero International's office. A 36 inch piece covers a standard single door opening and 72 inch covers a pair, but measure the finished floor opening rather than the door leaf, since the threshold runs the full width of the frame.
4) How much floor clearance do I need under the door for the Zero 103 threshold?
Plan for the 1/2 inch total height of the 103 measured from the lower floor surface. The door bottom has to clear the high side of the saddle through its full swing, so on a retrofit where the door was previously undercut to a flat floor you may need to trim the leaf or shim the frame. The .140 inch material thickness keeps the profile as low as an offset saddle can reasonably go, but it does not remove the 1/2 inch rise.
5) For a 36 inch commercial opening where the tile meets carpet, which threshold should I order?
The Zero 103 in a 36 inch length is the part that handles the floor level change directly. It is a commercial aluminum offset threshold, 7 inches wide, 1/2 inch total height, ADA and wheelchair compliant, and available in 36 inch and 72 inch lengths in Aluminum Clear Anodized or Dark Bronze. The Pemko 61 Series also comes at 36 inches, but it is an interlocking J hook threshold accessory in steel, so ordering it for the tile to carpet transition would leave the opening without its transition surface.
6) Does the Zero 103 threshold come pre-drilled for anchors?
No. The 103 ships undrilled, so you are drilling and anchoring it on site to suit your substrate. Zero will drill it at the factory if you submit a template to their office. On a retrofit that matters: if you are replacing an existing threshold and want to reuse the anchor pattern in the slab, an undrilled blank is actually easier to work with than one drilled to someone else's layout.
7) Is a 1/2 inch tall aluminum threshold strong enough for a high-traffic commercial entrance?
The 103 is a commercial-rated part, extruded aluminum at .140 inch wall thickness, and it is specified into office buildings, schools, healthcare, retail, warehouse, multi-tenant residential and government work. Mill finish aluminum resists corrosion without plating. For a fleet of openings in one building, the thing to standardize on is width and offset: at 7 inches wide with a 1/4 inch offset, every opening you use it on needs a floor height difference in that range, otherwise the threshold rocks or leaves a lip.
8) Do I need the abrasive tread option on the Zero 103, or is plain aluminum fine?
It depends on where the opening is. Plain mill or anodized aluminum is fine for a dry interior transition. If the threshold sees water, an exterior entry, a lobby that gets tracked snow, or a facility where a slip-resistance number has to be documented, order it with the non-stick epoxy abrasive bonded into the grooves: 1.02 coefficient of friction dry, 0.98 wet, which satisfies ADA, OSHA and most local code friction requirements. That is an option added to the 103, not a separate model.
9) What is the difference between an interlocking J hook threshold part and an offset threshold?
An offset threshold like the Zero 103 spans the doorway as a single 7 inch wide aluminum piece with a 1/4 inch offset height and a 1/4 inch upper saddle, giving a graded transition where two floor finishes meet at different levels. An interlocking J hook part, such as the Pemko 61 Series in steel construction, is a threshold accessory built around a hook profile that engages a mating component. They are ordered for different reasons: the 103 when the requirement is an ADA compliant transition surface across the opening, the J hook part when the assembly calls for that interlocking detail.
10) Will Dark Bronze on the Zero 103 threshold match the bronze door hardware on my other openings?
The 103 is offered in Dark Bronze and in Aluminum Clear Anodized, both in 36 inch and 72 inch. Dark Bronze is the one to pick if the openings already run dark anodized frames or bronze exit devices; clear anodized reads as natural silver aluminum and pairs with aluminum storefront. Both finishes are anodized aluminum, so foot traffic wears the finish rather than chipping a coating.
