Q: Hello, Can you give me some input on the attached detail? This is a pair of inswing, exterior wood doors, where the interior floor finish is concrete. The door has already been installed, and now I need to retrofit a door threshold. I realize the door is intended to sit over the highest portion of the threshold, but do you think this will work? The sill depth is 8 1/2". I am not wedded to using Pemko, but I saw your videos online and it looked promising. I have also attached two photos of the exterior door and flashing as seen here:

Thanks, Maria
A: What is the dimension from the bottom of the door to the top of the concrete pad?
Q: That dimension is about 3/4". It can be cut if necessary.
A: Can you route the bottom of the doors ?
Q: Yes, it is possible.
A: Is there a reason why you do not want to run the threshold underneath the door?
Q: o, there isn't. I am trying to avoid a custom door threshold, though. The drawing shows one possible configuration using standard Pemko profiles. The question is does it work as drawn? If I move the entire threshold over 2" to fit beneath the door, what do I do with the rest of the exposed flashing beneath? It is not suitable to be exposed; it's slippery.
A: Dear Maria
I do not think the seal as drawn is going to be effective because bristle is not going to be very effective at keeping rain out when it's compressed in that fashion plus also having a seal under the door means it's going to drag across the floor the entire distance from the open to the closed position 100% of the time.
I would rather see you install a combination of the following units -
front to back:

I'm going to ask that my weatherstripping expert take a look at your scenario and Supply to you an alternative take on this as well.
Thank you Richard
Q: This is very helpful! What connects the ramp (S411A) to the threshold (S285A)?
A: I can have them welded together if you like but here is a response from my weatherstripping expert:
Hello Maria,
Please review pages 116 & 117 of the Pemko full line catalog here:

And please draw your attention to where they have 1/4 inch and 1/2 inch heights both available. The FG in the part number is for the frost guard that is pictured in the photo which is installed beneath the door to keep frost and the cold from transitioning from outside to inside.
The 274x4_FG is a 8-1/8 inch wide threshold which is two 4 inch pieces connected by the frost guard in the center... It's available in Aluminum mill, Dark bronze and Gold anodized finishes. There is also a pemkote available that can be added to the Aluminum mill finish to give the threshold a slip resistant coating, if interested. They can be ordered at various lengths up to 185 inches.
A link to the Aluminum mill finish from the AB Supply website is here:

The thermal option is a really nice idea as well.
Especially in this scenario where the client is knowingly going to have standing snow on top of the threshold as evidenced in the initial photograph
If you have any questions about ordering or if you need anything else, please do not hesitate in letting us know.
Q: Hello again, Please see the attached revised drawing as seen here:

This is using the Reese Threshold Assembly components to achieve a slight slope to shed water. By the way, the width of the threshold is 93 3/4" wide so I would need to order 96" lengths. Thanks for all your help! I suppose I can just order on the website. Maria
A: you can - but we woulds love to take the order verbally for you - we think it makes "life easier" for the client.
If you would a CSR to call you - just let us know -

of the installed threshold. We screwed the front and back threshold components with masonry anchors and glued in the center flat plate. Thanks for all your help. Best, Maria
A: Very elegant solution and Jessica and I are glad to have been apart of the it (mostly Jessica - LOL)
