DO NOT BUY THIS DOOR! The instruction sequence is not correct and if you cut the tail wrong because the instructions don’t say to not cut one side until after it says to cut the rail to size. When calling customer service about the issue they are callus and offer next to no help except saying you have to pay another 100 dollars and 25 dollars shipping for the replacement part because their instructions weren’t written clearly. Save your money and time and look for a different door.
