The 5/16" Ruf Rod is one of the most popular sizes because of its versatility in both small and medium size ducts. It is the smallest of the wheel frames and at well under 3' in height or length, it is easy to store or load onto your vehicle. Although DCD only recommends lengths up to 800', the standard cage will hold up to 1,000'. The longer lengths should only be used in smaller ducts (up to 2-1/2" dia.) and when there are few bends. The deluxe version includes accessories as listed below. All accessories that attach to the rod can be glued in the traditional manner or can be clamped with set screws. For extra security, they can be both glued and clamped.
