Pemko 146B 36 – Frequently Asked Questions

1) Will the Pemko 146 threshold work with my existing door bottom, or do I need a special one?
The 146 is an interlocking threshold, so it only works with a matching interlocking door bottom hook. It ships with the #61 J-hook and nails, which is the piece that mounts to the door bottom and locks into the threshold channel. If your door currently has a plain sweep or a non-interlocking bottom, that sweep does not engage a 146 and you would be installing the hook as part of the job. Alternate hooks are available for other applications.
2) How does the Pemko 146 threshold keep water from blowing under the door?
Two things do the work. The interlocking hook forms a mechanical seal between the door bottom and the threshold, and the threshold carries interior and exterior weep holes that catch water driven or running under the door and route it back to the outside. That is the water return part of the name. For heavier exposure Pemko offers an aluminum water return pan (PAN) that goes under the threshold, ordered separately.
3) What sizes does the Pemko 146 interlocking threshold come in?
The 146 profile is 4 inches wide and 1-1/4 inches high, and it is cut to length. Stock lengths are 36 inch and 72 inch in mill finish extruded bronze (brass). The series runs from a 24 inch minimum to a 185 inch maximum overall, so wide entrances and multi-leaf openings are covered, and a 36 inch piece is the normal fit for a standard 36 inch residential entry leaf once you allow for the jamb-to-jamb dimension.
4) Is a 1-1/4 inch high threshold going to be a trip hazard or a problem for a wheelchair?
At 1-1/4 inches overall height the 146 is a tall interlocking profile, taller than the half-inch class of barrier-free thresholds. That height is what makes room for the interlock and the water return. On an accessible route you would generally be looking at a low-profile threshold instead; the 146 suits entries where weather sealing drives the detail rather than a flush transition.
5) What comes in the box with the Pemko 146 threshold, and what else do I need to order?
You get the threshold, the #61 hook with its nails, and WS #10 x 2-1/2 inch fasteners for anchoring the threshold down. What is not included and often wanted on an exposed entry is the aluminum water return pan (PAN), which is a separate order, and any alternate hook if the #61 is not the right profile for your door bottom.
6) Is the Pemko 146 threshold brass or aluminum?
Brass. The 146 is extruded bronze (brass) and the stock offering is mill finish, which is the raw unpolished surface that weathers to a natural patina outdoors. Brass gives it corrosion resistance for exterior thresholds where an aluminum extrusion would be the lighter, lower-cost alternative. The optional water return pan is aluminum.
7) Can I use the 146 threshold on a commercial entrance or is it residential only?
Both. Pemko types the 146 as a residential threshold and sill for pre-hung openings, but it is rated commercial duty, and it gets used at building entries, retail and office entrances, multifamily units, schools and healthcare entries. For a property manager standardizing across a building, the same 4 x 1-1/4 profile covers unit doors and the main entry.
8) Do I have to cut a 146 threshold to fit my opening?
Usually yes. The stock 36 inch and 72 inch pieces are cut to the jamb-to-jamb dimension on site, which is normal for a brass extrusion, and the hook on the door bottom gets cut to the door width to match. Measure the opening, not the door slab, before you cut.
