Our screen corners are available in external and internal styles in several sizes and colors. External corners are used in the production of straight cut windows screens and are visible on the screen. They are composed of plastic and come in colors that correspond to our screen frame. Internal corners are used with mitre cut window screens and are available in both plastic and aluminum with the latter being the more durable option. Choosing between straight cut and mitre cut corners is based on the customer’s own preference and whether they want to match the look of the window screen to the window. Mitre cut screens typically have a cleaner design aesthetic, however, if adjustments need to be made to the size of the screen, straight cut screens are easier to fix onsite.
