Perfecto Manufacturing APF34200 Glass Canopy Aquarium, 20 by 18-Inch

Dimensions are nominal so it will fit the standard tank. I prefer this to the original which had the handle attached on the wrong (to me the small one worked best) panel. You will need some care and muscle to insert the glass into the hinge, try inserting on one end first. Remember that the hinge has cutouts for the supporting lip on the tank, put the handle on AFTER you have the glass panels and cutout assembled the way you want it.

Products great. Finding how to obtain the product took me a while...

Fit my 27g cube... however the first one that came was completely shattered (Amazon sent a replacement right away) however.. I guess I applied too much pressure on it when I applied the plastic handle and I shattered it again.. I have a temporary glass hood that isn't the correct size but is working until I can justify buying this again. Gone through two of them though -- First one broke in the the transit between moving homes.

Glass Top fits perfectly on any Marineland Cube model, 27G, 37G, 47G. No problems with installation at all, and keeps moisture evaporation down to a minimum.

It's okay I guess - the led doesn't fit as good as I wished it would.

I received it nicely boxed. Canopy is described well and fit perfectly.

My fish tank is an odd size to find just any lid to fit on it, so after doing some research with the company who made my tank I was able to search by product number and found it cheapest through Amazon. After a year and a half my original lid had split at the seam, but that could have happened during a move. Also, when the lid shatters it isn't in as many pieces as a glass one. Clean up was much easier when it hit the ground. (That was due to circumstances not caused by the product).

I had tried to get a replacement top for my 47 gal column aquarium before from a different vendor. Two shipments later (with all the follow-up having to be done by yours truly) I still had nothing due to broken glass in the mail etc.Dealing with _this_ company through Amazon was simple and easy. I could track the package, it arrived fine and is exactly what I needed. Everything should be this simple.
