Choosing among these four products starts with understanding the job you're solving. One is an RV entry door window kit, another is a glass insert for an existing front door, the third is a complete exterior entry door, and the fourth is a large roll of screen mesh. The listed prices range from $95.99 to $669.99, so the right pick depends on whether you're repairing a vehicle, upgrading a home entryway, or patching screens.
Quick Take
If you're outfitting an RV, the 806621 Entry Door Window Kit is the only option with RV compatibility. If you want to add light to an existing front door without replacing it, the Pushglossy 22 x 36 Glass Insert is made for that. If you need a whole new front entry door, the 36x80 Smooth Surface Fiberglass Exterior Door with Brickmould is the full-door choice. And if you're handling screen repairs or DIY screen projects, the 36 Inch x 100 Feet Window Screen Mesh Roll gives you a long roll to custom-fit.

Product Notes
806621 RV Entry Door Window Kit with Low-Profile Shade, 12"X21" Black Replacement

Listed at USD 110.07, this kit is aimed at RV owners. The 12 x 21-inch black window includes a low-profile shade and is described as universally fitting with RV compatibility. The glass is tempered, which is a practical choice for a vehicle door that experiences vibration and temperature swings. It comes with the window kit components, so you're getting a coordinated replacement rather than sourcing parts separately. The main limitation is its narrow focus: it's an RV entry door window, not a general-purpose home window or a full door assembly. If your project involves a camper or motorhome, this is the one to consider.
Pushglossy 22 x 36 Entry Door Glass Insert White Exterior Front Door Window

At USD 329.99, this glass insert is designed to bring light and a clean white look to an existing front door. It measures 22 by 36 inches and is listed as a single-door insert with no handing, so it doesn't care which side the hinges are on. It provides privacy and security while letting natural light filter through, which matters if you want an open feel without a full door replacement. The limitation is that it's an insert, not a pre-hung door, so you'll need a compatible existing door and an opening that matches its dimensions. It also won't suit a double-door setup.
36x80'' Smooth surface Fiberglass Exterior Front Entry Door with Brickmould

This is the most complete option at USD 669.99. The 36 by 80-inch fiberglass door has a smooth, black surface and comes with brickmould. It's configured as a single, right-hand inswing door with a polyurethane core and Low-E glass, a combination that supports energy efficiency and privacy. The low-maintenance fiberglass surface resists dents and scratches. One important limitation: door lock accessories are not included, so you'll need to plan for separate hardware. It also calls for a rough opening of 38-1/4 by 82-1/8 inches, which is a specific fit for a new construction or replacement opening.
36 Inch x 100 Feet Window Screen Mesh Roll Black Durable Door Replacement

For the lowest listed price in this lineup at USD 95.99, you get a 36-inch-wide, 100-foot-long black fiberglass mesh roll. The durable black fiberglass material resists high temperatures and can be cut to fit windows, screen doors, porches, and patios. If you're doing multiple screens or a large porch enclosure, the length makes it a practical supply buy. The limitation is that it's raw mesh, not a finished screen frame or door; you'll need to measure, cut, and install it yourself. It's not a ready-to-mount door or window panel.
Final Recommendation by Use Case
If your project is an RV entry window, go with the 806621 kit. If you're refreshing a front door with more light, pick the Pushglossy insert. If you need a complete new fiberglass entry door, choose the 36x80 smooth surface door. If your task is screen replacement or a big DIY screen area, the 36-inch by 100-foot mesh roll is the practical choice.
