Single Flap Door Mount
Step 1 Prep Your Door



- If possible, remove the door from its hinges using a screwdriver and hammer to tap out the hinge pins. Lay the door flap for installation. Tape the provided template to the door. The top edge of the cut-out line should be at least 3” (7,6 cm) above the pet's shoulders.
Step 2 Drill the Holes



- Once you are certain the pet door will work with your door, make sure the template is level, and mark the outline with a pencil. Remove the template and drill holes through the corners just inside of the lines using a ⅜” (9,5 mm) drill bit.
Step 3 Saw An Opening



- Using a jigsaw, cut along the marked lines, making sure to cut straight.
Step 4 Check Weatherstripping



- Ensure the weatherstripping is firmly pressed in the groove on both frames. Weatherstripping indicated in red.
Step 5 Position the Frames



- Place the trim frame on the outside of the door and the flap frame on the inside.
Step 6 Position Screws



- Select appropriate screws and insert them into the pet door from the inside.
Door Width | Screw Length |
---|---|
1-⅜” (3.5 cm) | Short Screws (1-¾”) |

Step 7 Screw Door Into Place

- Once the pet door is leveled, tighten the screws so that the weatherstripping compresses.
Step 8 Attach Screw Covers

Step 9 Seal With Silicone

FAQ
Can I install this into a wall or window?If you want a wall entry pet door for cats, it might be best to invest in the Endura Flap Dog Door for Walls, but the flap might be too heavy for your cat to lift. Instead of a door installation, you might want to consider a cat door for windows instead, such as the Thermo Sash 3e Cat Doors for Sash Windows. |
Does this door have a lockable flap?You can lock this door with it's ABS plastic locking cover. The Ideal Pet Products Cat Flap Door comes with a 4-way lock while Petsafe, Cat Mate, and Sureflap sell electronic cat doors that lock and unlock when it detects either a collar key attachment or your cat's microchip. |
Can my dog use this door?Some pet owners report that their small dogs can share a cat door with their cats as long as it has a large enough door size. However, since this door has a taller and narrow flap design than most doggy doors, it may be best to invest in a separate pet door for your dog. |
Can I use this as an interior cat door to separate my cat litter box from the rest of the house?While this door was made into your patio door, there is no reason why it can't be installed indoors. |
