GMP Tools part 32283 is a 10 mm single-coil cable blower accessory finished in bright zinc plate. The single-coil configuration provides controlled spring action at the blower interface while the BZP finish protects against jobsite moisture and lubricant exposure. Specifying the correct 10 mm size and coil type is what keeps the blower head sealing properly and blow distances repeatable through microduct. A routine replacement item for contractors jetting fiber optic cable on FTTH and middle-mile builds. Available from Millennium as part #554495.
