We call these frames "Easy-Fix" They Feature "Twin Bars" with end "Nuts" that are designed to be unscrewed to allow fabric placement! (The most common method is by way of a channel) This means; you can give the "Messy Glue Method" a break! And have some great fun with these "Twin Hinged Frames" and their limitless and interchangeable application!
We recommend using this product to secure the end caps. This way, they are not likely to work loose and fall off!
You will also need a suitable tool to undo the end nuts, without marking them.
