I wouldn't recommend this product. In comparison to other installations this product is aesthetically inferior. Screws are external and accessible (they are "secure" screws). No frame provided for the double security door. Door was installed directly into a wooden frame. Initial service when quoting and ordering was efficient. However, there has been no effort to resolve my very legitimate concerns. Make sure their installation methods meet your expectations. They certainly didn't meet mine and I am living with a product where the installation quality is lower than what I indicated I wanted and what I expected with absolutely no recourse.

Approximate cost: $1700
