How to Choose an Adjustable Interlocking Threshold System

Zero Adjustable Interlocking Thresholds combine seperate components to form a threshold with your custom width and length requirements. The radial design of the connection allows the threshold to rotate and conform to surface irregularities. Threshold bases utilize interlocking hooks, rubber gaskets or thermal breaks to ensure superior performance.

Since the threshold comes in many parts, they are much easier to trim and fit than conventional thresholds. They install without exposed mounting screws on the base for better aesthetics and durability. Components are crafted from high quality solid bronze material and are available in Mill Finish, Oil Rubbed, Polished or Satin Bronze.

To begin choosing your threshold, determine the total width needed once combined. All parts are custom cut to your specific length.
