The GMX GM-TH001 universal speed-feed bump trimmer head is designed for quick line loading and dependable cutting performance in residential and professional trimming applications. Its wind-in-the-head design allows replacement line to be loaded without fully disassembling the housing, while the bump-feed system advances line during operation with a light tap on the ground. The high-impact nylon body features a durable matte black finish and is supplied with dark green trimmer line for a clean, professional appearance. The head supports commonly used 0.080-inch, 0.095-inch, and 0.105-inch line sizes and is suitable for many gas-powered string trimmers when installed with the correct mounting hardware. Always verify shaft thread, rotation direction, guard clearance, and the equipment manufacturer's fitment requirements before installation.
