Adds versatility to your ventilation system:

(1) Connects two pieces of Flexible Corrugated Yellow Ducting together,

(2) Stabilizes the open end of Yellow Ducting or Smooth Bore Ducting to control or stabilize the open-end of the ducting,

(3) Secures a Silica Dust Filter Bag to the ducting.

Each Stabilizer requires a ratchet strap to secure the ducting and/or filter bag to the stabilizer.
