Questions & Answers

Can this be used on a 2x6 bottom sill (framing)?

Asked by: Dave
I installed these on window rough openings with 2x6 framing. The main focus of these is to provide a seamless corner transition of the wall plane to sill/jamb. Flashing tape handles the rest. The depth of framing doesn't matter.

Do I need these on all four corners or just the bottom two?

so the title says for doors and windows, but the specs say for windows only. Which is correct?

Asked by: Philip
This corner flashing is 3.5 inches deep which works well for windows. In some cases It can also be used on doors; however some doors will require a 4 and 9/16 inch sill flashing.

3-1/2 in. SureCorner Flexible Corner Flashing for Window Installation (Box of 120) is rated 4.6 out of 5 by 67.

SureCorner flexible corner flashing for door and window installation served as a great supplement to the flexible sill flashing for my sliding patio. Hopefully, the combination of the SureCorner and the 6 in. wide Grace Vycor Plus flexible flashing will protect the subfloor/sill and all below it from water intrusion for a lifetime. I had to replace the 20 year old Crestline wooden (Aluminum clad exterior) patio door that came with my original home. I chose the United 4500 vinyl door for the second installation. In 1997 my builder installed the patio door with no protection of any kind to the subfloor/sill. Over the years water infiltrated and damaged part of: the fixed door panel (not his fault), the door sill, subfloor/sill, the exterior OSB sheathing, box joist, floor joist, insulation (between the floor joists), and the house sill. I had to fix/replace some structures before installing the new door. A replacement job became a repair and replacement job. Good luck with your projects.

I used these with Vycor flashing tape when installing new windows in my patio. If properly flashed will keep water from seeping down into and rotting the window sill. Very flexible, high quality. Recommend.

Rated 5 out of 5 by from Right thing for the job, needs to be stocked in stores Absolutely the best thing for the job. I just can't understand why Home Depot pays UPS to ship them to stores (free to the customer) and making the customer wait to get the product, instead of stocking them in stores.

Rated 5 out of 5 by from great item this item is what is recommended by window manufactures and installers and should be sold and stocked in the stores at all times.
