Single Door Kennel Boxes

The classic, aluminum-construction dog kennel.

Lightweight and roomy, the HPI Single-Door Dog Kennel Box offers a secure, comfortable way to transport your animal. Handles on both sides make moving this dog kennel very easy. Like all of our products, we offer the industry's only true lifetime warranty. Manufactured from 1/10-inch, military-grade aluminum and sporting the most secure locking mechanism on the market, our T-Handle safety latch, this heavy-duty kennel box can be placed on the deck of your truck bed, inside vans, SUVs, or even on the ground. A sealed floor with a 3-inch lip contains any liquid spills.

HPI Benefits

The HPI difference is in the materials we use, the attention to all details and ultimately products we produce and proudly guarantee. Our promise is to take the best care of your product while we manufacture it, and continue to care for a lifetime after you receive it.

Lifetime Warranty

All of our products come with a Lifetime Warranty against defects in manufacturing (failed welds, etc.). It also includes all locking mechanisms, hinges, gas shocks, weatherstripping and any other materials we use. Learn More

Military Grade Aluminum

Highway Products uses nothing but the best materials. Our products are hand crafted out of Military Grade aluminum. Why take it that far? The days of using nothing but the best ingredients are all but gone in this world. We refuse to sink to that level. That’s the HPI difference.
