20 x 36 Entry Door Clear Glass Insert (1 Lite)

This fit perfectly and was so easy to install. Excellent packaging that kept our new window safe and and in one piece.

I bought this to replace the one that was in the door. There is more than 1 size. I took the original one out and got the measurements then ordered. Needless to say it was prefect fit. Thank you.

I cut this window into my back exterior door, which had no window at all. Lots of welcome light in the cellarway now!Easy enough to do, I used my angle grinder with cutoff wheel to cut in rough opening on both sides of the hollow aluminum skinned door.

Positives - Exactly what I needed, perfect fit in my opening and (what should have been) a super easy installation! Packaging of the assembly was well done. IN transit, the outer box was punctured/damaged right where the glass would be. The item received no damage and after I opened it, you could see how well protected it was.Negatives - See pictures. I did not closely inspect the item (other than for clear breaks or damage). What I found was that after I fully installed the assembly that one side was not "seating" into itself properly. I didn't want to overtighten the screws as I didn't want to break the glass. I noticed that the screw holes were not lining up and pulling together, but I couldn't figure out why. I had to uninstall the whole thing and try to figure out what was going on. On closer inspection, I could see that the pane of glass on the top was off-center and was not allowing the assembly to be properly installed, flush against the door and itself. I knew I had 2 options: go through a return process which would leave me with an opening in my door in the middle of winter for who knows how long, or make some alteration to make it work. I opted for making the alteration. You can clearly see that the glass was not allowing the screws to pull tight against the other side of the trim. You can see where I notched the mounting hole at an angle to try to get "around" the glass, but that wasn't enough. I had to make a prominent notch (90° x 90°) to allow the glass to lay flat and still let the screw get into the mounting hole. What should have been an easy installation took far too long, I had plastic shards all over my work area from "carving" and for all I know, I may have degraded some of the structural integrity of the whole thing.I will gladly change my review and rating with a response and appropriate action from Amazon and/or the manufacturer.

Straight-in proper fit. The unit matches the photo and matched the unit it was replacing. Easy to install, just want to have flat space/surface to work on and I used some lengths of wood and clamps to hold the unit in place to the exterior side while securing the screws on the interior side.

Kicking myself for not getting this sooner. Crazy easy to install. Literally took less than 10 minutes.

Did exactly what it was supposed to

The product has a really bad packaging that uses styrofoam so the glue that is supposed to waterproof the window will get to the styrofoam. Also some glue that won't dry is coming out of the windows and it will trap dust. The craftsmanship is really bad.I would not get this product.
