Please find this product at http://absupply.net/ This video is to bring you a closer look at
the Pemko 121G. This is a gold anodized aluminum threshold. It is interlocking style. This
is a smart little threshold, and here is what I mean by that. It is a very narrow profile,
it is a very short height, and it is interlocking. Now interlocking is going to be used in those
instances where you want a positive mechanical seal at the bottom of the door. And how that
is accomplished is with the included hook strip. This is a piece of white coat galvanized
steel, looks like they call it a J strip or just a hook strip. Looks like the letter J
if you use your imagination. And how this is intended to be used is that you will have
an application and there is no hard and fast rule how you install this. You can see that
the sides are not symmetrical, it would be my guess realistically that your exterior
is going to be the wider side and assuming that the door swings in, the hook strip will
be nailed to the bottom of the door and as the door closes, it makes a sort of mechanical
connection there, allowing for a very positive seal at the very bottom of the door. The hook
strip has a little kink in it here just from where they cut it, but you get the idea that
when they close the door, it locks in just like this. A lot of people who have used interlocking
thresholds continue to do so because of their proven effectiveness is the bottom line. Metal
doesn't really wear out and these hook strips while they are available separately and are
bought with some frequency, they only get damaged or replaced because they are unintentionally
damaged. You might have a shoe, or something, a rug underneath the door and someone goes
to open the door and it catches and damages it, tears it off partially. it is held on
with nails and this can be attached flush to the bottom of the door or some people will
mortise so this gets tucked up inside so they can have a little profile that would look
a bit like this to the situation. Versus just nailing it to the bottom of the door as drawn there. Either way is done. Like I said, extremely
effective lets get the tape measure and check the dimensions and since I've got the hook
strip in my hand, lets go with that first. Just so you have an idea it is about 7/8"
overall width, and an overall height is going to be just about 3/16", 1/4", I realize it
is a bit tough to see. Now the threshold itself and there is an image below this video showing
everything important dimensionally about the item. It is 3" wide and has an overall height
of 5/8". Now your door is going to reside over the flattened crown area of the threshold,
so your undercut you can get away with something quite tight. A 1/16" or 1/8" at the very most
from the top of this portion to the bottom of the door something at 3/32", your hook
strip will have the ability To tie into the side you install it on. Really
nice interlocking threshold. Available in milled aluminum finish, dark bronze, obviously
gold. Available in several different lengths as well. If you have need for a custom length,
by all means let us know by indicating in the comments field what length you want us
to cut the material back to. The reasoning is if you had to take this 48" piece and cut
it down to 44", you would eliminate that counter sink and the next one is all the way over
here. So you would be stuck with drilling a new hole, then your centers will not be
exactly correct, may or may not matter to you. But if you were to order a custom length,
we will locate that first countersink the proper distance from the edge, and the center
as well. Interlocking thresholds are used in wood door applications, exterior wood door
applications, fiberglass doors and that is going to tell you that it is primarily residential.
I see these installed here in Chicago interlocking thresholds are everywhere, especially homes
that were built in the 1950's and 1960"s and 70's. Side doors into the kitchen of the home,
single family bi level house. These are everywhere and they work splendidly, they work effectively.
They are nice because a typical door sweep will fatigue with time much sooner. You've
got material that is dragging against the floor, scraping against something, getting
exposed to extreme temperatures, exposures to ultra-violent which will degrade things
like vinyl, where that mechanical seal is positive and very long lasting. Pemko is a
full line manufacturer of all things weather stripping related in both commercial and residential
arenas. So if this is something that is exactly what you need to fit your job, feel free to
