Adjustable Interlocking Threshold System

Adjustable Interlocking Thresholds combine many parts to form a threshold with your custom width and length. It also has the added benefit of an interlocking hook or door rabbet which will seal the gap under doors to prevent water and air seepage. Additionally, this threshold system can be used on surfaces that are not perfectly level. The circular design of the connection allows the threshold to rotate and conform to surface irregularities.
