Endura Flap™ by Patio Pacific - Kennel Door (Set of 2)

“It’s all about the flap!”

This Kennel Dog Door combines all the features of the award-winning Endura Flap™ with a beefy metal frame. It is identical to the Endura Flap™ single flap version for doors, except that parts not normally needed for a kennel application have been excluded:

  • The external trim frame
  • Installation hardware
  • Template
  • Weather stripping
  • Decorative hole plugs to hide the screw heads
  • The locking cover assembly (kennels normally use a separate "guillotine" type locking mechanism). 

Sizing Information

The easiest way to test flap size for your pet is to cut a hole in a piece of cardboard that is the size of the flap you are interested in, then coax your pet through (use treats if necessary). Place the cardboard in the opening of a door so they have to walk through the hole to get to the reward! See what flap size and step over height (height from floor to bottom of where the flap will be installed) works best for your pet.

Every year, animals are harmed by rigid flaps. The typical situation is that the pet is partway out the pet door, is startled by something and jerks back suddenly. The pinching effect of a rigid flap in that case can be terrifying and cause the pet to pull back even harder. 

It was for this reason that the first design requirement of the Endura Flap was that the flap be flexible and safe for any pet and for any child who should happen to crawl through!

Of course there is a trade-off here. Rigid flaps can be more chew-resistant than flexible flaps. If chewing of the flap is expected, it is best to take some preventative measures. One of the best is to mix some Habanera pepper with Vaseline; and smear this mixture on the edge of the flap. Be careful not to allow any of this mixture in the dogs eyes!

Secondly, if a guillotine door is placed on the inside of the run and the dogs are kept inside when that unit is closed, then the dog cannot get to the flap to chew it.

We suggest you read the complete story behind the Endura Flap™ and for engineers or those looking for some more technical information here is a 74-page dog door energy efficiency study showing what makes it so special.

Some Additional Notes:

  • The Endura Flap™ Kennel door is intended to be installed in either a solid core wood door or in a wall that has been framed out. If you wish to install the Endura Flap™ kennel door in a hollow core door, you'll need to frame out the hollow core door first. Alternatively, you can use a regular Endura Flap™ pet door for doors which is "self-framing" though more expensive.
  • If you wish to install the Endura Flap™ Kennel Door in a wall and don't want to frame the wall yourself, you can purchase the Endura Flap™ dog door for walls in either single or double flap versions.
  • It has been our experience that the Endura Flap™ seals so well that the single flap model will meet most needs even in areas that experience four seasons. However, for really extreme weather, the door mount version and the wall mount version are both available in double flap models.
  • There is a significant difference between the rough cut out of the Endura Flap™ Kennel version and the regular Endura Flap™ for doors. The regular door mount cut out is larger to allow the bolts to fasten directly to the trim frame. The kennel version is smaller as we intend wood screws (not included) to be used to fasten the frame directly to the door or wall. The kennel door itself should be used as a template or use the rough cutout dimensions given above.

Installation Instructions

  • Kennel installation can vary greatly depending on the material the kennel is built with and may not require the hardware typically used in a residential application. So we exclude the external trim frame, installation hardware, template, weather stripping, decorative hole plugs to hide screw heads and the locking cover assembly. If you are installing this in a home on a people door we suggest going with the regular Endura Flap™ pet door for doors
  • To determine the area that will be needed to accommodate the door, measure the dimensions of the extended section on the back of the unit . This section of the door will be fitted into the wall. Use screws (not included) to attach the outside frame.
  • The frame ensures a tight seal and secures the door to the wall.
  • Note: Don’t forget to use a level.

Ask a Question


LTL (less-than-truckload) Freight is used when shipments are 120 lb+ or for oversized equipment, which results in a truck with a large container delivering your order. Our freight carrier will contact you once your order makes it to the distribution center closest to the delivery address specified, and set up an appointment time for delivery.

Pet Pro Supply Co. Free LTL Freight Shipping - Curbside Delivery

Our standard Free Freight Shipping option for LTL deliveries is curbside, which is to a delivery to a Commercial Address and does not include a liftgate. If your order is to be shipped freight, you will have the option to specify whether the item will be delivered to a Residential, Limited Access, or Commercial address. If there is no option to select a shipping location, then this cost is already included in the price.

We strongly recommend adding the optional Liftgate for all deliveries to locations without a loading dock or forklift.

Freight Delivery Locations

This option specifies whether the delivery location is a Commercial, Residential, Residential Business, or a Limited Access address.

  • Commercial - These addresses are those defined by our freight carriers and/or zoned by local municipalities as commercial sites. Typically these addresses are zoned as commercial real estate or are used exclusively for business. Most commercial sites have tractor-trailer access and a loading dock.
  • Residential - If the address used a residence, select this option. This includes Apartment/Condo complexes and dormitories.
  • Residential Business - Any business being operated from a home, apartment, or other dwelling where people live on the premises is considered to be a Residential Business.
  • Limited Access - Locations where deliveries are restricted, limited, or very far from a distribution center. Examples Include:
    • Place of Worship
    • Restricted Areas - Secure Research Facilities, Military Bases/Installations, Correctional Facilities, Government Buildings
    • Farms, Ranches, and Rural Areas
    • Recreational Areas - Camps, Parks, Fairs, Carnivals, etc.
    • Individual Storage Units
    • Sites - Convention Centers, Construction Sites, Mines
    • Schools and Universities
    • Commercial establishments not open to the walk-in public during normal business hours

Freight Liftgate

A liftgate is a hydraulic lift that is attached to the back of a truck that can lower freight to ground level. Freight carriers prevent their drivers from assisting with the unloading of heavy equipment other than using a liftgate to ground level. We highly recommend any delivery address without a loading dock, select this option.

However, please know that for certain very long items, such as Kennels over 6' in length, a Liftgate will not be able to bring the entire order down to ground level. Please have the necessary manpower available to receive your items with limited delay to the driver.

So far, great product

Did not take long for the dogs to figure out and works quite well !!
Recommendation to manufature:
Did not come with plugs to cover the holes for the screws on the outside...would be nice.
Great product!

Great durable door

I liked the first pair I bought so much, that I purchased another set for the other side of our house. Great product at a great price! Built to take a beating & last years! seals out the cold in winter & the mosquitos in summer!

Very pleased with kennel doors

I installed 4 of them in my house before winter. They work great! Strong enough to take a Shepherd hitting them, and still seal against the cold wind. My cats have even learned how to use them.

Absolutely EXCELLENT product!!

We live in Northern Ontario on the border of upper Michigan. Winter nights can get to as low as -40F !!
needless to say, we wanted something that would provide the most energy efficiency so our dogs would be comfortable in the communal kennel room while we were at work all day. I couldn't be happier with the 2 door kennel package I bought. Price was conservative (since I didn't need the close out panels or decorative plugs for the screw holes!). The flap is an awesome construction of double flexible lexan with full strip magnets along
both sides as well as the floating threshold bottom. This is an awesome product that definitely keeps out the draft & cold. High wind magnets can be added for additional resistance!!
Hats off to Patio Pacific.... I am thrilled!
