The versatile Invisible Corner Trim offers two clever solutions in one. Perfect for achieving a seamless look at standard 90-degree internal corners where you want the trim completely hidden from view, it can also be used as an external trim for 270-degree corners when a visible finish is desired. This 2800mm aluminum profile maintains essential water protection while giving you design flexibility. As with all our aluminum trims, we recommend applying a bead of sealant during installation for optimal performance.
