48″ x 42″ Custom Aluminum Retractable Screen Window

A 4-foot window just under four feet tall, the kind in kids' rooms and home offices, takes the 48″ × 42″.

• Good spots: a child's bedroom facing the yard, or a home office you air out between calls.
• How it opens: the mesh draws across the window when you want it and gathers into a slim side channel when you don't.
• Options: black or white, and either Standard, which pulls across from one side, or Center, where two panels meet in the middle.

Warranty: 2 years from delivery. Also available in custom sizes and colors — quoted per order.
