Skutt Envirovent 2 Kiln Vent - Extension Kit
An 8 foot length of flexible 3 inch diameter aluminum ducting is supplied with your original Envirovent 2 Venting System. If the distance from your kiln to the blower motor is greater than this, you may need additional ducting. This depends on how high up the wall you are ducting and how much stretch you can get from your 3 inch flexible ducting.
The Envirovent 2 Extension Kit includes 8 feet of aluminum ducting (3 inch diameter), one 3 inch coupler, and two hose clamps.
