Storm doors are thinner than entry doors, so most dog doors won't fit them. The Security Boss Heavy Duty Storm Dog Door is made for them: it fits storm doors typically 3/4" to 1 1/8" thick, uses an insulated aluminum frame and clear flexible flaps, and locks when you need it closed. It's made in the USA.
| Size | Pet opening |
| Small/Medium | 7" x 9" |
| Medium | 9" x 12" |
| Large | 11" x 16" |
| Tall | 11" x 20" |
| Wide Tall | 15" x 20" |
| Mammoth | 15" x 24" |
How to measure: the opening should be a little wider than your dog's widest point and a little taller than their height at the shoulders.
Measure the solid lower panel where the pet door will go. Most storm doors are between 3/4" and 1 1/8". If yours is thicker, call us and we'll help you pick another model.
Entry doors are usually 1 1/4" to 2" thick. For those, choose the Standard Door Mount or the MaxSeal PRO for Doors.
If the pet door goes in a screen panel rather than a solid panel, see the SB4 Pet Door for Screen Enclosures.
Yes. The locking mechanism closes the pet door when you need to keep pets in or other animals out.
