The Beiter Winder Lite Kit contains four high-impact plastic parts designed to change the Profi serving tool into a light-line serving bobbin. One side-screw is removed from the bobbin, allowing the stainless rollers to swap out in seconds. Along with the plastic end lugs, the Winder weight is decreased for proper tension using lightweight spectra threads. Also included is a spare industry-standard jig spool for loading your preferred serving thread.
