My windows are 3 feet wide. Do they made a 3 foot sock?

Hi Cecelia & Earl! The PIG105 Mildew Resistant sock is 3"D x 48"L. These socks can be somewhat molded to fit your window by making a 'U' shape to fit your window. Another option you can try is to move the filler aside and add two zip-ties tightly to the sock leaving about 1/4 inch between the two zip-ties. You would then cut between the two zip-ties to create whatever size sock you need for your window. Please let us know you we can be of further help!

Should these be placed on plastic to protect floors if placing inside sliding glass doors as prevention from water leak during Hurricane?

This is a great question. The PIG105 Mildew resistant sock will absorb the water and any water inside the sock will also be touching the floor. If you have wood flooring or other flooring that can be damaged from the water, you can place plastic down first, this will help keep the water absorbed in the sock from coming in contact with the floor and potentially damaging it. Stay Safe & Please let us know if we can be of further help.

Rain leaking through brick wall in 20+ spots and puddling on floor, reaching 6' into loft at worst spot. Do I need sock, barrier, other? Wall is 18'.

Hi there! The sock will be effective at absorbing the water you are seeing leak through. Some kind of moisture barrier might be effective as well at some point. Please feel free to contact us at 1-866-434-4744 if you have questions.

What us the size if the box that these come in? I need to know how much space those 12 socks will take up.

Hi Judith! The PIG105 Box dimensions are 22.75"L x 11.5"W x 18.25"H. You can also remove the socks from the box and place them in a plastic bag to reduce the footprint as well. Please let us know if we can be of further help.
