Pemko 136D 36 – Frequently Asked Questions

1) Will the Pemko 136 threshold work with my existing door bottom sweep, or do I need a matching hook seal?
The 136 is an interlocking threshold, so it is not a standalone part. It has a raised hook profile that a matching door bottom must engage to make the seal, and the 136 is built around the 61 J-hook configuration. If the door already has a plain sweep or a non-hook bottom, that sweep will not interlock and you will not get the water return action. Pemko does offer alternate hook options on this style to match different door bottom seals, so match the hook to the bottom you plan to run. Buy the threshold and the interlocking door bottom together and you avoid a second trip.
2) What length do I order for a standard 36 inch entry door?
Order the 36 inch length for a standard single 36 inch door, and the 42 inch length if you have a door plus sidelite or a wider opening that needs the threshold to run past the jambs. The 72 inch length covers a pair of doors or a patio unit. Pemko runs the 136 from 24 inches up to 185 inches, so anything odd can be cut from a longer piece. If you are unsure, measure jamb to jamb at the sill, not the door slab.
3) I am replacing a threshold on an existing door. Will the 136 drop into the same spot?
Not automatically. The 136 is 4-7/8 inches wide and 1 inch high, so before pulling the old one, measure the width of the sill area and check the gap under the door slab. If the outgoing threshold is narrower or lower, the 136 will either overhang or reduce your undercut clearance. The other half of this is the door bottom: the 136 only performs as intended with an interlocking hook seal on the door, so a straight swap from a flat saddle means adding a door bottom too.
4) What finishes does the Pemko 136 threshold come in, and which one holds up outside?
Three: mill finish aluminum, mill finish extruded bronze (brass), and dark bronze anodized aluminum. Mill aluminum is the raw, unfinished look and is the usual pick when the threshold is under a storm door or otherwise out of sight. Dark bronze anodized is the same aluminum with an anodized coating, so it holds its color under foot traffic and sun better than bare mill. The extruded bronze is a solid brass base rather than aluminum, which is what you want when the rest of the entry trim is brass and you need the threshold to match.
5) Does the Pemko 136 threshold come with screws, or do I need to buy fasteners?
Fasteners are included. The 136 ships with WS #10 x 2 inch wood screws, which is what you want driving into a wood sill or sub-sill on a residential pre-hung opening. If you are anchoring into concrete or a masonry stoop, those wood screws will not hold and you will need masonry anchors sized to the same hole pattern.
6) What does the water return on an interlocking threshold actually do, and do I need it?
The interlock catches water that blows or runs under the door and channels it back to the outside instead of letting it reach the interior floor. It matters on exposed openings, doors with no overhang or a shallow one, and anywhere driving rain hits the entry square on. On a protected door under a deep porch, a plain saddle threshold does the same job with less height. Pemko also offers an aluminum water return pan (PAN) separately for the harder conditions, where you want a drainage tray under the threshold as well.
7) Is the Pemko 136 threshold suitable for a commercial opening or is it residential only?
It is built for residential thresholds and sills on pre-hung openings, which covers single family entries, patio and sliding door units, and apartment or condo unit entries in multi-family. For a commercial storefront or an aluminum entrance with heavy traffic, look at a commercial saddle or thermal barrier threshold instead. Property managers standardizing across a residential portfolio can run the 136 on every unit entry and keep one hook profile across the building.
8) Can I cut the Pemko 136 threshold to fit a narrower opening?
Yes, aluminum and brass extrusions like the 136 cut cleanly with a miter saw and a non-ferrous blade, which is how most installers size a stock length to the opening. Buy the next length up from your jamb to jamb measurement, cut one end, and keep the factory end at the hinge side. Pemko does produce the 136 in lengths from 24 up to 185 inches, so on a large job you can order closer to the finished size and cut less.
