Pemko 142B 36 – Frequently Asked Questions

1) Will the Pemko 142 threshold fit a standard 36 inch residential entry door?
Yes. The 142 Series interlocking threshold is stocked in 36 inch and 72 inch lengths, and the 36 inch piece covers a standard single 3-0 entry door opening. The 72 inch length is there for wider openings or a pair of doors. The aluminum extrusion runs 4 inches wide by 5/8 inch high, so you need 4 inches of clear floor depth under the door for it to sit flat.
2) Does the Pemko 142 threshold need a matching hook on the door bottom, or does it work with a plain door?
It needs a hook. The 142 is an interlocking threshold, meaning the door bottom carries a #61 J-hook that drops into the channel in the threshold as the door closes. That interlock is what makes the water return work. The #61 hook and nails come with it, along with WS #10 x 1.5 inch fasteners for setting the threshold itself. If your door bottom profile does not suit the #61, Pemko offers alternate hooks. Plan on prepping and fastening the hook to the door bottom as part of the install, not just screwing down the sill.
3) Can I use the Pemko 142 threshold on a fire rated door assembly?
Yes. The 142 Series is UL 10C positive pressure and UL 4L10 listed, so it can go under a fire rated residential door assembly without breaking the listing. That is the version you want for a rated corridor or unit entry door in multi-family work, where a non-rated sill would fail inspection.
4) What is the difference between an interlocking threshold with water return and a plain saddle threshold?
A plain saddle just bridges the gap in the floor. The 142 does two more things: the door bottom hook drops into a channel in the sill, and the sill has a return trough that catches water blown or driven under the door and sends it back outside. That matters on a weather-exposed entry with no overhang or a door that takes wind-driven rain. On a protected interior or garage-to-house door with no water exposure, you are paying for a hook prep you do not need, and a simple saddle is the easier install.
5) What finishes does the Pemko 142 threshold come in, and will it match dark bronze entry hardware?
Two: mill finish aluminum and dark bronze anodized aluminum. The dark bronze anodized is the one to order when the unit entries already run dark bronze hardware and you want the sill to disappear rather than flash silver at the base of the door. Both finishes are stocked in 36 inch and 72 inch lengths, so you can standardize a whole building on one look.
6) Can the Pemko 142 threshold be cut down to fit my opening?
The 142 is an aluminum extrusion, so it cuts cleanly to length on site with a miter saw and a non-ferrous blade. Order the 36 inch for a standard single door or the 72 inch when you need to trim to something in between or cover a wider opening. Cut from one end and keep the water return channel intact through the full width of the door.
7) Is there anything else I need to order with the Pemko 142 threshold to finish an exterior door?
The threshold arrives with what it needs to install: the #61 hook and nails for the door bottom and WS #10 x 1.5 inch fasteners for the sill. The one add-on is the aluminum water return pan (PAN), sold separately, which sits under the return to carry collected water away on openings that take heavy exposure. Alternate hooks are available if the #61 does not match your door bottom profile.
8) Is the Pemko 142 the right threshold for pre-hung door units in a multi-family building?
That is what it is built for. The 142 is a residential threshold and sill for pre-hung openings, and the combination of a UL 10C and UL 4L10 listing with a water return makes it a fit for unit entries in townhomes, condos, and apartment buildings where the door is both rated and weather exposed. Ordering the same finish and length across the property keeps replacement stock down to one part number.
9) Will a 5/8 inch high threshold be a trip hazard or a problem for accessibility?
At 5/8 inch overall height, the 142 sits low enough to walk over comfortably, which is the usual reason a residential entry gets an interlocking sill instead of a taller commercial ramped one. It is 4 inches across, so the rise is spread over a shallow profile rather than a hard step. For the exact accessibility requirement in your jurisdiction, work from your governing code for the opening type.
