Product Details
Thermo Panel Height and Thermo Sash Width Extensions
These are a part of the exclusive anti-whoops feature on all Endura Flap patio and sash window pet doors. The extension is also compatible with Dragon and Whiskers & Windows brand aluminum panels.
You mismeasured! Now you have to send the pet door back for the correct size. Not so fast! If you purchased a Thermo Panel or Thermo Sash you might be able to salvage the situation by using the "anti-whoops" feature:
- To make your panel 3/4" taller or your sash 3/4" wider, you may purchase an extension (or create your own using a 1" thick piece of wood painted to match).
- To make your panel slightly shorter or sash narrower, you may trim the U-Shaped flange up to 3/4" with a metal hacksaw.
If you need a substantially higher or shorter panel that doesn't fall into the standard Patio Pacific height adjustment ranges, then you may purchase a custom height Endura Flap‚ Sliding Glass Pet Door.
Size & Measurement Guide x
Track Measurement Guide x
In order to choose the correct panel size, you will need to measure your sliding glass door track.
Please Note: These instructions are for channel-style sliding door tracks. If you have a monorail track, these instructions do not apply.
Step 1Find the Lowest Corner of Your Track

- With your sliding door open, insert one end of your measuring tape at the deepest point of the lower corner of your sliding glass door track.
- Make sure the tape measure is flush to the corner. There may be a part of your door track blocking the lowest point of the corner.
Step 2Find the Highest Corner of Your Track

- Line the measuring tape up the side of your doorway, stopping at the highest corner. Make sure the measuring tape is flush with the corner and is not blocked.
- The distance from the lowest corner of your track to the highest corner of your track is your sliding glass door track height.
- Select the Height Adjustment Range that includes your track height. Some brands have custom options if your track height does not fall into one of the ranges.
Step 3Measure Your Track Width

- Using your tape measure, find the width of the bottom track your sliding glass door slides along.
- Most aluminum panels require a track at least 1" wide and most vinyl panels require a track at least 1.5" wide.
- Check the product details to ensure the panel will fit in your track.
Size Chart
Flap Size | Flap Dimension | Stock Code |
---|---|---|
Small | 6" w x 11" h | 13PPC06 |
Medium | 8" w x 15" h | 13PPC08 |
Large | 10" w x 19" h | 13PPC10 |
Extra Large | 12" w x 23" h | 13PPC12 |
NOTE: The size of the height extension is about 3/4 inch. Choose your patio panel pet door size based on the chart above so we can send you the right width. If the height extension of 3/4" is not the correct size, you can also put a piece of lumber in your panel track to extend the height.
Installation Instructions
FAQ
How do I know if I need to purchase this? The height and width extensions are made for when you purchase a Thermo Panel that is too small for your doorway. It adds about ¾” extra length to your Thermo Panel. You can also create your own with a 1” thick piece of wood, but it will not be as aesthetically pleasing. |
What do I do if the panel I purchased is too tall for my doorway? If it off by less than an inch, you may be able to saw off length from either the top or bottom of the panel to bring it to size. As long as your Thermo Panel is not a custom length, you can return it within 90 days of purchase. See your return policy for more details. |
I have an odd door height. Will this help the Thermo Panel fit into my sliding glass doorway? Yes, it can! This is great for when your door is between door range sizes. However, if there is more than ¾” difference between the panel size and your doorway, then you should invest in a custom panel insert height. |
How do I know what size to get? You need to order the size that corresponds to the size of your pet door flap. For example, if you ordered a small Endura Flap pet door, you should order the small height extension piece. |
Will this affect my door’s insulation value? It can, but we highly recommend lining the inside of the extension piece with weather stripping to prevent any loss of energy efficiency. |
