Purpose of little door seal wedges?

What's the purpose of the little tapered adhesive-backed squares that come in the hardware bag of pre-hung exterior doors? The door already has stripping all around so why install the pads?

Is it a shim you can use to keep the door centered in the jamb when installing?

No--way too soft and per instructions they are installed last.

I'm happy to follow the instructions and use up all the bits in the bag--but do wonder WHY those are included.

Many times the bottom of the weather stripping is sandwiched by the adjustable threshold. The wedges are inserted behind the weatherstripping and attached to the side jamb. It holds the stripping out away from the door to provide a better seal.

People don't like to see light at the corners of the door. Most often the pads are installed right at the threshold, tucked behind the vertical weatherstrip as Czizzi mentioned. Sometimes you put them on top if you can see light at the top corners. You almost always have to put a staple in them as the adhesive sucks.

I had an Anderson door rep tell me there to devert water away from the threshold to jamb seal.
Made 0 since to me.

Per Jeld-Wen instructions (most other manufacturers have similar wording)...

"The included foam wedges are used to complete the weatherstrip seal at each bottom corner between the jamb and operating slab(s) when closed. Position the thick edge behind the weatherstrip, remove the backing paper and adhere to the jamb as shown."

Their installation instructions can apply to almost any brand and are much more comprehensive than most.

The jamb-threshold joint is "supposed to be" caulked with sealant prior to installing the foam pad.

See step 8a in these sample instructions.http://www.enduraproducts.com/images...stallation.pdf

Step 5 in Gunguy's link.

Probably one of the steps that gets skipped most frequently.
