Frequently Asked Questions

All products are shipped from our U.S. production facilities in California and Illinois, minimizing transport costs and transit times so that you have the product you need, when you need it.
The DDB1-U has the center divider removed to accommodate doors that have an astragal — the vertical molding or seal that runs between the two door panels on a double door unit.
An astragal is a vertical molding or seal mounted on one or both doors of a double door unit. It covers the gap between the two slabs when closed, providing a weather or sound seal. The standard DDB1-F's center divider would interfere with this component.
Like the DDB1-F, the flap can be stapled to a 1"x4" wood runner at the bottom of the jamb legs, or the part can be screwed directly into the slab bottoms. The removed center divider clears space for the astragal.
The DDB1-U is designed for 1-3/8" slab doors with an astragal.
