Flat Roof Security Barrier

The Hale Flat Roof Security Barrier™ (patent pending) is designed to be installed directly in front of the pet door, obstructing the view of the pet door as well as blocking human access.

The barrier is designed so that the dog enters from the side on the open end (available on either end) and must turn to use the pet door. An animal can wind its way through but the limited space and angle of entry make it extremely difficult if not impossible for a human to access the pet door.

This wood model is constructed of 7⁄8" cedar boards. It can be ordered (at no extra charge) prestained in a natural cedar color or left unpainted and unstained. The barrier could then be finished upon installation in whatever manner you desire (i.e. to match the exact paint and trim colors of the people house or in any other exterior finish required—such as stucco).

If desired, you can add other options to the barrier to fit your decor or needs. For example, place plants on top of it to make it look like an outdoor planter. Make the wood model into a garden potting bench for an additional work area. Place a bench cushion on top and have an extra seating area on your patio or deck. The wood model is also available with a polymer top and could be used as a workbench. Use your imagination and make it hide in plain sight. For illustrations of these ideas, click here. The barrier can either be attached directly to the house wall or anchored into the ground next to the house. It is available in ten standard sizes to complement our entire line of pet door sizes. Depending on the height at which your pet door is installed, an optional floor kit and ramp kit are available to offer easy access for your pet.

The flat roof security barrier is also available with an optional pet door frame and flap. (pictured on the unstained model below) This is available in any of our four standard pet door frame colors.

It is equipped with a false top that comes with an optional alarm installed for added protection.

Hale Pet Door Security Barrier optional alarm

Additional Security Options Available:

The Hale Security Barrier™ is designed with a false top that can trigger an alarm if someone tries to move the barrier. (It can also be installed without an alarm if desired.)

The simplest option is the small included battery operated alarm that sounds for approximately 90 seconds if the top is removed. It is designed to be turned on and off with a key. (shown to the right

Other available alarm options include tying the Security Barrier into your home alarm system or fitting the barrier with a motion detector or electronic beam. These can be set to trigger if a person larger or taller than your dog approaches the security barrier. 

Hale Pet Door Security Barrier wooden dividerCentral Security Divider

One outstanding feature of the security barrier is the inclusion of a sturdy center divider that blocks visual and physical access to the pet door. This means that a human would not even be able to see that there is a pet door in the house wall and would not be able to access it. The barrier and divider are designed so that a dog can weave through the barrier and access the pet door while a human cannot bend in that manner. The divider itself is made in either one or two pieces that can be adjusted into different positions to accommodate stockier or leaner dogs. Obviously the wider the divider, the more difficult it would be for a human to fit between the divider and the side of the dog house. The standard wooden barrier comes with a wooden security divider. Its size and placement vary depending on the size of barrier ordered. (See the picture to the left.) See the diagram below for how the pet would access his door with the wooden side entrance barrier or the optional front entrance.
