A: Hello, Jara. As well-explained by Robert, EZ Screen system is engineered to install into existing structure. The 1x2 open back extrusions frame the interior of an opening created by walls/posts and floor and ceiling and the 2x2 post extrusions divide that framed area. The 2x2 extrusions can divide horizontally or vertically or both. Our capri bracket clips are used to attach the divider posts within the framed area, so the ends are not exposed. And all of that is to say, EZ Screen does not have end caps for the ends of the 2x2 extrusions! If you wish to fashion an end, you might use expanding foam in the ends. Let it cure. Trim it even with the extrusion. Sand it slightly and then touch up the color with Behr Cracked Pepper to have it blend with your project. Thank you! Carrie (EZ Screen Team Member)
A: Generally these are installed INSIDE a post and beam like structure in a way where no ends would be exposed. For example these 2x2 beams are used for POSTS the go from floor to roof and for a horizontal divider between the posts and so the ends would not be exposed. The 1x2 version is attached the existing structure like the TOP and wood posts. See installation guides for details.
A: I'm not sure I understand. For most cases you will use the 2x2 with the double tracks for the top header. If this is a custom door and top header is all the way to top board, you can opt for the 1x2 or the 2x2 . The extra track doesnt matter how you use it. Take a look at the video on the product page, it gives you plenty of examples. Specifically at the 2 min mark is the door section example.
A: HI Bobo. No, we do not offer a 2x2 with only a single spline groove. Thank you for your question. Dan H. (EZ Handrail Dev. Team)
