The window is good, but I wish there was a place for the metal closing rod to hook into to close, and that the flange around the border was larger, something like 1.5" would make a lot more sense for a window this size, especially the larger ones.
We installed this window (24x36) in a metal pole building. It’s great. Vevor provides great customer service, sending instructions when I wanted to replace the panel with a real glass window. It installs easily (if your skills are basic, hire a professional) and is water tight and functional. Will buy again.
Really a solid window but you really need to make the window opening very tight because the flange/trim that sits on the exterior of your opening is only about 1 inch wide, which makes it very difficult to to drill into your window opening. If you give your self even 1/8 of an inch wiggle room on both sides you will have a hard time hitting your window frame. Please redesign this widow with a 2 inch exterior flange and it will be perfect.
These windows are great the only issues i have is with the shipping and the packaging. Packaging is lousy there is no protection on the corners. If these are dropped by the shipper on a corner expect the corners to be damaged. They need to do some better packaging to protect there products better. Luckily I was able to bend most of it back straight and still use it. Like I said before these windows are great i have no complaint on the windows its just there packaging and shipping.
