Recently a customer wanted to attach a den pipe to her large 8" diameter pipe so we made this mesh connector for the job. It is possible to do the same for 6 inch pipe to a den but that does require a door or pipe clamp (NOT included here)
Mesh fitment for connecting two different sized pipes together. 8 inch link is complete in itself. Picture shows an 8 inch connection.
6 inch requires 1 x door or pipe clamp adding to this order.
