The LEFITPA Replacement Bump Knob is designed to slot into Bolens trimmer models BL100, BL110, BL150, and BL160, replacing the common part numbers 791-153066, 791-153066B, and 153066. Built to endure outdoor use, this knob offers a comfortable grip, a robust feel, and a precise thread that aligns with standard bump-feed assemblies.
