I've replaced a few screen doors with what the big box stores had available and they have been very disappointing. Lightweight frames and cheap plastic rollers. This door frame is considerably more heavy duty and has metal wheels top and bottom. The door glides MUCH better and I have confidence that the frame will last longer because of how it's built. It was shipped in a large heavy duty cardboard tube and the assembly was very simple. I'd suggest you watch a youtube video on how to rescreen a sliding screen door to get some pointers if you haven't done it before. This door is a far superior choice to what I can get at the big box stores for the same price

Do not be surprised, the door came in a Corrugated Tube not a flat box like I thought it would. You will need an extra hand to assemble, but once assembled it was easy to install. The door rolls smoothly on the track and latches tightly into place. Definitely worth the money and will last for many years to come.

The product came very fast and I was able to install it myself. It fit perfectly in my door frame.

I was a little apprehensive about getting this door based on some of the reviews because, while I do a lot of DIY stuff around the house, I have never installed a screen in a frame before. In the end, the door arrived on time and in good condition (though the end of the tube was a bit difficult to remove), and the assembly was not difficult, particularly after watching the video. Even better, the door fits perfectly in the frame of our 40-year-old sliding glass door and is so close in color to the door that it looks like it came with it. My only less-than-positive comment would be that the description on amazon makes it sound like the door is heavy and solid. It's not. I wouldn't call it flimsy, but it is not what I would call "heavy duty", though for the price it seems about right. Happily, our sliding glass door was mounted backward when the house was built, so the screen door is on the inside and I don't have to worry about it standing up to the elements.

Putting this together I was surprised that the four sides didn't interlock. It's held together by 8 sheet metal screws. It seems to work well though, the screen was a pain to put on. I found it easier to put it on while the door was already up on the frame. A decent buy
