Pet Door

Excellent product excellent company!!

Pet door

The security boss pet door is the only door we offer to our customers, it’s security and build quality is above the rest. Since the very first one we installed for someone we have only had positive and happy customers. I like these pet doors so much that I ordered and installed one in my house even though it wasn’t necessary since I already had a pet door. Besides the price being a bit high, there is nothing bad I can say about the products or the company that supplies them. I will continue to recommend and install them for my customers. A+ security boss!
