Poor craftsmanship

Would Not Recommend

This door looks good, but it was assembled very poorly. Several of the nails missed the frame all together and protruded through the frame. The hinges were at least 1/4" out of line and the door was 1/2 inch from the top of the frame and so close to the threshhold that it would not open without removing the sweep on the bottom. Some of these problems were not noticable intil the door was installed and had to be modified to make it work.
