Height Adjustment Ranges

  • B- Shorty 75" - 77 3/4" (additional cost)
  • C- Regular 77 5/8" - 80 5/16"
  • E- Tall 93 3/4" - 96 1/2" (additional cost)

Step-Over Options - These options can be extremely important in properly fitting your pets. They are offered as drop-downs after the size, height and color choices are made.

Custom Height Add-On Extension - If your sliding glass door track is not accommodated by one of these height ranges, you can special order a height extension for either the Regular or Tall panels. Be sure to read the Details tab carefully to see how to compute how tall you'll want the custom height extension to be.  If you already have the Ideal "Fast Fit" Panel but it's too short for your slider you can purchase just the Ideal "Fast Fit" Height Extension.

Replacement Flaps and Parts You can get just the replacement flap at Ideal "Original" Replacement Flaps or you can get both the flap and the plastic frame a Ideal "Fast Fit" Replacement Flap Assembly.

If your measured track height is near the bottom of the adjustment range then you should review A Note of Caution.

Wondering how to measure your track? Review our Track Measuring Guide.

The maximum over-all height you can achieve in this manner is 110-½," and the tallest the extension should be built is 14." It can be made to 16", but the manufacturer suggests that you would then semi-permanently install it for stability. Because the height extension is built to your custom dimension, it is not returnable, though the panel itself is (provided you haven't ordered any other custom feature like an outside keyed lock or custom step-over).

In Depth Ideal 'Fast Fit' Installation

Q: Does the Ideal Fast Fit pet doors for sliding doors require tools for installation?

A: Yes, you will need a drill if you want to install the locking mechanism.

Q: What locking mechanism can I use for the Ideal Fast Fit?

A: The door comes with a pin lock you can install. Alternatively, you can purchase a Charley Bar for added security.

Q: What is the formula for determining the height extension needed for a given track height on an Ideal Fast Fit patio dog doors?

A: Calculate the height extension needed for a given track height by subtracting the maximum height of the adjustment range of the panel you've chosen from the measured height of your sliding glass door track and then add back 2-1/8".

Q: What extension would be needed for a track height of 90" for the Ideal Fast Fit Panel?

A:  An 11 3/4" extension would be needed because the medium height adjustment range goes up until 80 3/8".  To get this answer you use the formula (90” - 80 ?”) + 2 ?” = 11 3/4”

Q: Does the Ideal Fast Fit Panel have an adjustable step-over?

A: No, the Fast Fit does not have an adjustable step over. However, you can get a custom step-over. Keep in mind that the custom step over cannot be adjusted once built, and it does make the item non-returnable.

Q: Does the Ideal Fast Fit Panel door include a Draft Stopper?

A: Yes, this door does come with a draft door sliding glass door draft sealer

Ideal “Fast Fit” Sliding Glass Cat Door

Q: Can the Ideal Fast Fit come with an electric door?

A: Yes, it can come with a one way magnetic cat door, it’s the Ideal E-Cat Electronic Panel.

Q: Why would someone decide to choose the keyed lock option for their Fast Fit door?

A: If you enter and exit your house using the sliding glass door, then you will want to have a way to lock up the from the outside when you leave. Because the lock from your slider doesn't mate with the dog door in sliding glass door, you'll want to add the keyed locking option, which does make the panel custom and non-returnable.

Q: Can I purchase the flap and frame together for my Ideal Fast Fit panel?         

A: Yes, the Ideal Fast Fit Flap and Frame Assembly are available for purchase. Please make sure you are ordering the correct logo for your specific panel.  If you no longer have the original flap, you can figure out what logo you have a couple of other ways. You can measure the entire width of the panel, as these measurements changed when the manufacturing location did.  Another option is to unscrew the frame from the patio panel, if it's one piece that screws directly into the sides of the aluminum frame, it's an old style rectangular logo.  If the frame is two pieces that screw into each other (not the metal panel directly) than it’s a new style round logo. If you still have the original flap (plastic frame), you may be able to figure out which flap and frame you need by looking at this page
