Duct Rodders and Accessories

• Why does the outer layer of the rodder peel off as it travels through the eye? Will this cause the rodder to wear out faster?
  This is caused as the rodder rubs against the manufactured bushing; however, there is only minimal wear to the outside layer at first, no structural damage occurs, and the reliability of the rodder is not affected. Also, although no rodders have failed as a result of this minor wear, future models will be constructed with a stronger, machined bushing to prevent wear on the bushing itself. Condux is committed to ensuring that you are provided with a long-lasting, high-quality product.
  
  
• Why don't you have the size duct rodders I need in stock?
  Duct rodders are made-to-order in multiple lengths. In this way, your order is built to your exact specifications.
  
  
• What is the longest distance you can push a rod?
  This depends on several variables. The duct rod length is determined by the rod diameter and type of rod (Cobra, Mini-Cobra, or Python). The recommended rod size is determined by the size of the conduit, which is also related to the minimum bend radius. Please refer to the recommended duct rod size chart and the duct rodder ordering charts to determine the correct type of rod for your needs.
  
  
• What is minimum bending radius?
  The minimum bend a rod can sustain before fracturing.
  
  
• How are bending radius and duct size linked?
  The larger the duct, the larger diameter rod needed. You can use the recommended duct size chart to determine which size you need.
  
  
• What can I use to help rod crooked or partially obstructed ducts?
  The roller guide and flexible leader both help guide the rod around bends, sweeps, and misalignments.
  
  
• Can you push 1300 feet of 5/16" rod?
  No. 5/16" Python rod can be ordered at a maximum length of 1000 ft. Also, column strength prevents rod from being pushed past a certain distance.
  
  
• What is the advantage of fiberglass rod over steel rod?
  If steel rod breaks, it cannot be repaired. Fiberglass rod may be repaired with a splice kit, which may be ordered separately or as part of the accessory kit.
  
  
• If I have a 200 ft. rod and a 300 ft. rod, but I have to rod 400 ft. of duct, do I need to buy a longer section?
  No. You may use a swivel coupling to join the two rods together. The swivel coupling may be ordered separately, or as part of the accessory kit.
  
  
• What determines the cage size?
  Cage size is determined by the minimum bending radius of the rod.
  
  
• How do you put the rod back in the cage?
  You push it in. If you try to put the rod back in by turning the cage, the rod will break.
  
  
• Why do you have to use the rodder on its side?
  For safety. The rodder cage can tip over, causing personal injury.
  
  
• What if you break a rod?
  Repair it with a splice kit, ordered separately or as part of the accessory kit.
  
  
• How does the "spring effect" and the placement of the eye help installation?
  The rod is completely straight when manufactured. After being wound into the cage, the rod still "wants" to assume its original form. The placement of the eye guides the rod forward at the the point where it begins to straighten out, thus utilizing the "spring-effect" to help push the rod.
  
  
• What is the flexible leader used for?
  The flexible leader helps guide the duct rod around bends, sweeps, and misalignments.
  
  
• What is a disadvantage of the swivel coupling?
  The swivel coupling adds straight length and decreases the bending radius of the rod, which can making pushing around bends more difficult.
