Most sliding doors are 72x80 and so is mine. You sell no sill which is 72 in. The closest one is this one of 78 in. Does that mean that I can reduce it by cutting it. The picture above does not suggest that one can cut it shorter.
Asked by: Stratos
Thank you for using SureSill! Yes, 78" or 80" long pan can be cut down for 72" rough opening. SureSill recommends middle section of the pan the "Channel Plate" to be 1/4" shorter then the RO, so when the End Caps are glued in, the sill pan fits properly in RO, for installation instructions see SureSill WMG (Water Management Guide). In the real world, every RO is a little different, so being able to customize the sill pan length for proper fit is very useful.

Asked by: MDA
Sill pan comes in 4-9/16" and 6-9/16" sizes. The former is intended to be used for 2"x4" wall installations, and the latter for 2"x6" wall installations. 4-9/16" = 3-1/2" stud + 1/2" drywall + 9/16" sheathing. Likewise for 2"x6" walls where stud depth is 5-1/2" instead of 3-1/2". The 4-9/16" pan must be used with a 4-9/16" jamb door and similarly with the 6-9/16" jam, although the 4-9/16" jamb door can be installed in a 2"x6" wall installation using jamb extensions that are notched at the bottom to fit over the back vertical edge of the pan.

How do i know what width of sill pan to buy?

I have an entry door to my garage that I would like to replace.No one thought of putting anything under door sill when it was installed.When the rain hits the door,it runs down and into garage.Is your product expandable or must you cut it to fit?What kind of wheel do I need so material will not bust when cut?
Asked by: phantom33
Typically, all garage floors are constructed at the front of the garage to force water drainage outward and away from the entrances to the garage. Hence, your problem is not the door collecting rain that runs down and under the door toward the interior. A simple fix that would not require a door replacement is to glue a rubber strip on the floor to block the water behind the sill location. It must be securely sealed and closed at the door jamb on both ends. Now, if the new door is a definite GO, you may want to consider that the house entries use a sill plate that will work fine with the new door on the garage (recommend metal) if sealed properly when installed. If your budget allows, you can hire someone like me (retired military) that has the skill and ability to economically provide a permanent solution to your dilemma. Don't worry, Be Happy...! The problem is not a serious one. "G-Day pardner"

4-9/16 in. x 78 in. White PVC Sloped Sill Pan for Door and Window Installation and Flashing (Complete Pack) is rated 4.2 out of 5 by 9.
Rated 5 out of 5 by from Quality Sill Flashing This quality sill flashing was easy to install and provides confidence that my newly installed patio door will be leak free for years to come.

Rated 2 out of 5 by from Sloped Sill Pan The idea of a durable waterproof system around the window was my reason for purchasing the sill pan. I was disappointed with this product. The window I was installing was a replacement for an existing window. The depth dimension was too big and required trimming, which undermined the waterproofing. This flashing might work better for a new construction installation. I found it difficult to tie into the water shed and the window did the same job with no fuss. You also have to use the glue that comes with the kit, regular PVC cement won't work. The gluing surfaces don't match exactly so you have to flood with cement, clamp, and then seal the seams when you are done.

Rated 5 out of 5 by from good product Bought this as it was recommended in the JeldWen patio door installation manual. Unfortunately it did not work for my application as the doorwall depth past the nail fin was about 1.5" shorter than the suresill pan. I like the product design concept and I really wanted to use it, however it did not work out for me. Great product nonetheless

Rated 5 out of 5 by from Seems to be working. We had a sliding door that leaked during strong rain. The pan was very easy to install and seems to be working. We've had two storms and have not seen any water infiltration. We have a basement entry door that we're going to replace soon. We plan on installing a sill pan there also.

Rated 3 out of 5 by from Door Sill Pan OK The end caps are a bit flimsy compared to the sill pan portion of the assembly, but otherwise it was fine.

Rated 4 out of 5 by from nice idea needs better guidelines for how to measure to insure proper fit.

Rated 5 out of 5 by from great product. If flashing and tape were to leak this will defiantly keep the water out.
