The BES fib223 Chain Snake is a wall-fishing kit combining a 10-foot chain and a flex-fish magnetic retriever for routing wire and cable through uninsulated wall cavities. The flex-fish head bends in any direction and holds its set shape, allowing technicians to navigate around obstacles inside walls without losing position. This tool is used by electricians, low-voltage installers, and AV or data cabling professionals who need a reliable method to pull wire through finished or framed wall sections without destructive access.
The fib223 is suited for residential and light commercial installations where wire and cable must be fished through uninsulated stud bays and wall cavities. The 10-foot chain length provides adequate reach for standard wall heights and typical floor-to-ceiling runs. The magnetic retriever end is compatible with attachment kits, making it adaptable for use with a range of wire-pulling accessories depending on the application.
Compatible with attachment kits as noted by the manufacturer. Designed for use in uninsulated wall cavities in residential and light commercial framing applications.
Installation is typically performed by licensed electricians or low-voltage cabling technicians. Verify the wall cavity is uninsulated before use, as insulation will impede the chain and flex-fish movement. De-energize any circuits in the work area before fishing wire through wall cavities per NEC guidelines. Avoid forcing the chain around sharp framing edges that could damage the retriever or kink the chain.
