New DuraStack Half and Full Angle Rings

DuraVent has added a new Half and Full Angle Ring to the DuraStack product line. The new half and full angle rings are used to support and guide the stack.


  • Half Angle Rings are used as saddle supports in horizontal and sloped runs.
  • Full Angle Rings are used as guides for vertical runs of pipe to maintain alignment and provide lateral support while still permitting vertical expansion.

The inside diameter is 1/8" larger than the outer diameters of the stack, allowing movement of the stack within the ring. Full Angle Rings include hardware to assemble the two halves together. Please refer to installation instructions for appropriate spacing.


  • Manufactured with stainless steel
  • Available in standard lead time
