Zinterlock aluminium split battens provide a simple and secure method for flush-mounting signs, panels, displays, mirrors, cabinets and other large objects on flat surfaces. Zinterlock’s strong aluminium extrusions fit together to form a “split batten” which can support large or heavy objects indoors or outdoors.  Zinterlock remains hidden from view, while enabling the object to be flush mounted onto the backing surface. A security pin locks the battens together, ensuring that the object cannot be lifted from its mount.
