-          I think you shipped me a one-way door, I ordered the “Heavy Duty Dog Door ® which is 2-way door.


We get this call enough times to place it on our FAQ list.  The unique design of the Heavy Duty Dog Door ® and Big Dog Door ™ allow them to be 2-way operating doors, while looking like one-way doors.  These specific doors work in both directions with the assistance of 4 hinges.  Referencing the dog door mounted on the exterior mounting surface, the entire dog door assembly (frame and acrylic panel) opens when the dog exits (all 4 hinges were used).  When the dog returns, only the acrylic panel moves through the tunnel (only 2 hinges were used) allowing the dog to return to the house/garage/kennel room. 

A lot of us are visual learners so even after the above is explained, a few customers insist that we ship them the 2-way door they purchased.  Depending on how I think the customer will react, I sometimes say, OK, you got me, we only sell one-way doors, because you see my kids are going to college and I need you to purchase 2 doors so I can double my revenue!  SILENCE is often the result.  Then I resume and say OF COURSE we would not sell one-way doors.  If so, we would not still be in business after 30 years of offering these dog doors.  So, we often ask them to install the door on the mounting surface to visualize how the door functions.  It is fun and rewarding to “hear” the lightbulb turn on as the customer now understands how our unique two-way dog door operates.  As soon as the customer understands the dog doors functionality, we often hear many wonderful comments about how ingenious the design is and then a lot of positive comments about how the door is made of such fine material and the most “heavy duty” built dog door they have seen.


-          Do the doors lock?

The doors are secure when you add either our Drop-In Panel or Guillotine Closure kits.  The closure kits are mounted on the interior of the application.  This way the pet is allowed to use the door when you decide.  Check out either our Drop-In Closure Panel Kit or the Guillotine Closure Kit.  We offer kits specific to the dog door you purchased or can custom make the size that fits your needs.

-          How long will it take to ship?

We do everything possible to ship the exact same day you ordered.  The only exceptions are orders placed late in the day, weekends, and Holidays.  We ship with UPS and USPS.

-          How are these mounted?

Before we talk about how the doors are mounted, let’s understand your application.  If your application requires the purchase of our PVC Trim Kit, then the trim kit is installed first and fastened with 8 total screws.  The next step is to install the actual dog door onto the trim kit.   This only requires 2 screws!  We have customers of all handyman skill levels and even the rookie handyperson is able to install our trim kit and dog door in under 5 minutes (this does not include creating the rough opening or framing out the rough opening to accept the PVC Trim Kit to ensure there is adequate material to fasten the PVC Trim Kit and Dog Door to – this takes around 15-20 minutes.

If your application does not require one of our PVC Trim Kits, then the dog door mounts to the mounting surface with only 2 screws (included with purchase). Yes, 2 screws holds the door to the mounting surface.

-          How to properly trim doors

 Door openings are trimmed out with our PVC (both wall and door applications) or Wood (only door application) kits.  Otherwise, you're welcome to have your contractor or yourself trim them out with the appropriate wood and or aluminum material to cover up the sharp edges and internals of the mounting surface.

Dog Owners

-          I have dogs of different breed, some are big and some are small. What Door should I get? How should I install it?


This question is more a function of our recommended clearance between the dog’s chest and the dog door frame.  We recommend the bottom of the rough opening be 2” below the dog’s chest.


If you have dogs that are of significant size difference, we recommend you use the Big Dog Door ™ or Easy Big Dog Door ™ which when installed low, will accommodate both sized dogs.


Kennel Owners

-          I’m building a new kennel, how should my contractor trim out the openings?

This question applies to the single door customer or a customer who is having a large kennel built by a contractor.

The first step in installing our dog door is to ensure your install height it determined. We recommend the rough opening to be 2” below the dog’s chest.

Next, we want to make sure you have created a frame that has material strong enough to fasten the dog door to.  There are too many applications to cover all of them in this answer, but generally speaking, you need to make sure the fasteners (screws) will be securely fastened into the mounting surface.

We then would recommend that you purchase our PVC Trim Kits.  Our PVC Trim Kits are made to fit all of our dog doors.  NOTE: The rough opening size required is slightly larger compared to the dog door opening required size!

If you and your contractor would like to use material on hand to trim out the tunnel, we recommend making the “picture frame” out of green treated lumber.  Leave 2.5” clear from the rough opening then the contractor can J-Channel around that rectangle.  The 2.5” clear area can be and is recommended to be covered with flashing or some other material to 1) prevent moisture from getting into the “picture frame” and deteriorating it over time and 2) cover up the rough edges of the tunnel.
