We purchaced a sliding door with a doggie door attached for $1500. 00 and after waiting for 2 months it came in and delivered. However after the door was sealed up the doggie door does not open and the frame is 1/16 inch open at the bottom when opened. I have called Lowes and they told me to call the manufacture. After 3 calls and over a week later someone will call me to instruct me how to take the doggie door apart in hopes that it will work however the opening at the bottom also concerns me as it appears the bottom of the door is 1/16 inch larger that the top part. Also the sliding door open 24" and not the full opening as other sliding doors. Due to the doggie door it will not open more that that. After spending $1500. 00 for the door I am not happy. Thank you Lowes for not taking care of your customer after I have spent thousands of dollars with you.
