Review: Great for energy efficiency and moisture prevention. - This product is something I couldn’t find in a big box store, but it is perfect. Easy to install, and it helps provide a very nice look and will certainly help prevent moisture incursion. This was my second purchase, because I thought the one I used on my front door was so perfect. Review: Good fit. - I was nervous about using this, as I have never used a sill pan before. What concerned me was the depth. It was a perfect fit. It laid down with the edge overhanging my 3/8" siding on our shed, and the inside just slightly beyond the edge of the door sill. I think it would have been perfect if the outside siding had been 1/2", but not beyond that. The PVC cement set up quickly. It did however soften the underlying oil based paint I had put on the floor two days earlier, which is something I had done for extra protection, which is not normally done in a door installation. The price was higher than other sources, but instead of waiting a week or more from a Home Depot or Lowes, it was here the next day, so I can't complain. ## Features - Best Waterproofing For Door and Window Sills - Easy Installation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BTJ675S | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #132,781 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #4,149 in Building Materials | | Brand | jamsill | | Color | White | | Customer Reviews | 4.6 4.6 out of 5 stars (190) | | Date First Available | March 13, 2013 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 1 pounds | | Item model number | CECOMINOD061393 | | Manufacturer | JAMSILL GUARD | | Material | ABS Plastic | | Maximum Gap Fill | 40 Inches | | Number of Pieces | 1 | | Part Number | CECOMINOD061393 | | Product Dimensions | 5.5 x 2 x 20 inches | | UPC | 645128005010 | ## Product Details - **Brand:** jamsill - **Color:** White - **Material:** ABS Plastic - **Maximum Gap Fill:** 40 Inches - **Number of Pieces:** 1 ## Images ![4 9/16 Up To 40" Door Window Pan Flashing - Image 1](https://m.media-amazon.com/images/I/8125XvjLV6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for energy efficiency and moisture prevention. *by D***N on September 30, 2025* This product is something I couldn’t find in a big box store, but it is perfect.
