BT Duct Rod & Accessories
FAQs
BT duct rods (also known as cobra rods or rodder systems) are used to locate, clear, and pull draw ropes or cables through underground BT ducts. They enable engineers to:
- Locate blockages in BT ducts
- Pull draw cords through long duct runs
- Assist with new fibre pulls or sub-duct installations
- Inspect or test duct integrity
BT rods are manufactured to BT specifications for compatibility with the UK Openreach duct network.
Netceed supplies a full range of BT approved rods and accessories, including:
- BT PVC duct rod is standard rodding for locating and pulling through ducts
- Rod ends and attachments like threaded ends, pulling eyes, leaders, and guide tips
- Flexi-lead and bullet heads help navigate bends and reduce snagging
- Duct brushes for cleaning and debris removal
- Joiners and repair kits to extend rod length or fix damaged rods
- Rod frames and reels transport and pay-out control
All accessories are designed for safe, smooth rodding in BT duct systems.
Choosing the right rod depends on duct size, distance, and job conditions:
- 6-9mm rods for best for short or moderately obstructed ducts
- 11-14mm rods are suitable for long BT duct runs and more challenging routes
- 50-300m lengths, pick a length that avoids unnecessary joins
- PVC or glass-reinforced options are strong yet flexible rods for BT networks
For long, bend heavy routes, choose larger diameter rods for better push strength and durability.
For safe and effective use:
- Always inspect rods for cracks or splinters before use
- Use appropriate guide tips to avoid damaging existing cables
- Never force the rod through severe bends or obstructions, identify and clear first
- Wear PPE, especially gloves and eye protection
- Secure the rod reel to prevent backlash during rapid pay-out
- Use BT approved pulling eyes and rope to maintain compliance
Following these practices reduces the risk of rod breakage, duct damage, or injury.
