Large Dog Patio Insert for Sliding Glass Doors


[photo] Giant Breed Sliding Glass Door Insert Security Boss Manufacturing LLC now offers a patio insert sized for extra large to giant breed dogs for sliding glass doors. This unit will fit any sliding door system from height ranges of 70 inches up to 99 inches. The generous pet opening is 15" inches wide x 28" inches high. You can choose between 4 various step over rise options to elevate the pet opening to the correct height for your dog. All Security Boss Products are hand built to order.

[photo] Giant Breed Patio Pet Door SB Standard doors The rule to remember when sizing a pet opening for a dog is to allow 1.5-2" clearance above the dog's shoulders so that when the dog passes through the opening, they will not pinch the flap at the top. The step over rise should be easy to step over. It is always prudent to think of the dog's mobility as they age. Some breeds have more of a tendency for arthritis and hip problems.

All Security Boss Inserts come with an extendable brace bar that will lock your door into place. 

Security Boss Patio Pet Doors allow customers to easily insert and remove the patio pet door so that you can retain the full use of your sliding door opening if you choose.

The top spring-loaded adjusting section of all Security Boss Patio Pet Doors appears as an "H" piece when viewed from the side. The overall width of this piece is 11/16" (Will fit into most any sliding glass door track).

The spring-loaded adjustment provides for a 3.25" range for proper fitting into your opening. Most top tracks in sliding glass doors do not have any center rails, however, if you do have this feature then the Insert can straddle any rail at the top 9/16" wide or narrower.

The spring-loaded top is secured with 2 thumbscrew locks, accessible from the interior only, so that someone from the exterior of the house would not be able to compress or remove the unit.
[photo] Security Boss Patio Pet Door bottom view

The bottom section of all Security Boss Patio Pet Doors have an overall width of 3/4". A semi-circle, "C" channel is centered and runs the length of the bottom. This "C" channel is design to straddle the center rail in the channel on the floor that your sliding glass door follows.

By straddling this center rail, the Patio Pet Door will remain centered to the frame of your sliding door when closed to this unit.

Note: If the center rail in the channel on the floor is wider than 5/16", then this patio Insert will not be able to straddle it and as a result may not fit properly in your opening

Measuring for the Patio Pet Door:

To determine which height range will work with your slider, open the slider and measure from the very bottom inside track to the very top inside track. As you look down on the groove that the slider follows on the floor, you may see a thin rail. You will want to measure down past that rail, from the deepest part of the channel on the floor to the very top inside channel above.

Will These Patio Pet doors fit all Sliding Doors?

As you look at the track on the floor your slider follows; you most often will see a "rail". If this "rail" is narrower than 5/16" (as you look down on it), then the Security Boss Patio Pet Doors should fit your slider.

What is the Rise?

This is the distance from the bottom of the patio insert to the bottom edge of the pet door frame. The Rise elevates the pet opening. For example a 2" rise will be the same as setting the pet door itself on a 2" block. There are several different rise options available (2", 4", 6", and 8" inches) to accommodate different pets. Selecting the rise along with the proper sized pet opening should result in the opening being higher than the shoulders of your pet to prevent the flap from pinching and also result in an easy step over height that they can use even as they age. As a rule of thumb, a pet opening should be 1.5 - 2" higher than your tallest pet's shoulders.

Included Weather stripping:

Every Security Boss Patio Insert features a replaceable bulb seal that lines both sides of the insert. This bulb seal provides a superior weather seal between the insert and the wall and sliding door. This weather seal can also be replaced if needed very easily by sliding the weatherstripping into the t-slot groove on your patio pet door.

The weather seal is a 3" wide vinyl weather stripping section that attaches to the back side of your sliding door. When an insert is installed, your sliding door breaks the seal between the slider and fixed panel. This weather stripping will seal out any drafts.

Adjustable Height Range:

The top section of the Security Boss Patio Pet Door floats on two tension rods that compress or expand to obtain the best possible fit in the patio door frame. The top is fit into the upper patio slider track and the bottom rests on the bottom slider track. Once in place, there are two thumb bolts that lock the top section into place to prevent the Patio Pet door from being removed from the outside.

How does my Sliding Door Lock?

We strongly suggest bracing the door with a stick or an adjustable brace bar; as this immobilizes your slider and is the most effective way to secure your sliding door. We also offer several locking devices for purchase if your situation requires.

Different ways to Install the Patio Pet Door:

The Security Boss Patio Pet Door can be mounted on the stationary side of the patio door. Many patio doors have stoppers that normally prevent the stationary panel from moving. If these stoppers can be removed, the stationary panel can be moved to accommodate the patio panel.
Note: This technique will not work on patio doors where the stationary panel is molded into the frame.

Use of Extensions Ranges:

Security Boss makes 4 different height ranges of patio pet doors. You can add 2 inch extensions to the top of all insert heights to extend their reach or adjustment range. These extensions snap into the top of your insert and fit tightly. No screws or hardware are required. It is possible to add more than two (2) extensions on the Security Boss Inserts. The snap in lock feature of the extensions allow for a stable firm unit regardless of the number of extensions are added. This is a great benefit to those who might move to a home with a taller sliding door system.
