Blast Gate 6" Dust Collection for Sewer and Drain PVC;

This blast gate is specifically designed to fit Sewer & Drain PVC ducting product ASTM D2729. Not recommended for use with metal or spiral metal ducting, however, wrapping tape around these products will allow a snug connection. 6" Flex Hose can be inserted into the opening (not on the outside) and must be sealed with tape or caulking for proper use. There are other ways to modify the ducting source to work with this blast gate.
