The DISA lock ring compliments the duct system, clipping over the rolled duct collar. The lock ring has an inner gasket to ensure that an air tight seal is achieved. It requires no tools to assemble or modify and is secured by an R Pin.

Fast and easy to use, the lock ring can be re-used if repositioning is required.
