Dog Agility Tunnels


Norvent Mine & Tunnel Ventilation formerly Schauenburg is a leading manufacturer of dog agility tunnels supplied to all of North America. Our tunnels are extremely durable, made from 16 oz PVC fabric or from premium textured Sure Grip fabric in 19 oz PVC material. Both fabrics are UV resistant to fading, weatherproof and mildew and rot resistant. Tunnels are available in small (18″), regular (24″) and large breed(26″ diameter) and come in standard 10′, 15′ and 20′ lengths. Special lengths can be manufactured as required. You have a choice of 4″ or 6″ coil pitch. Pitch refers to the spacing of the wire ribbing. We also manufacture Tunnel Saddle Bags complete with carrying handle straps.
