• 【IMPORTANT PRE-PURCHASE NOTICE】This spool is not a universal type; its spool dimensions and center hole size differ from both single line spools and blue double line spools. To avoid buying the wrong size spool,please check the model number on your trimmer - usually located on a label near the motor or battery connector, or measure the size of your trimmer.
• 【INSTALLATION TIP】This is a dual line spool, so it is recommended to pinch both ends of the line when unravelling it so that the spool doesn't come apart for quicker installation on the trimmer and better use of the auto feed function.
• 【NEWLY UPGRADED PREMIUM MATERIA】YWTESCH weed eater string made of PA6(Nylon) & 30% GF (Glass Fiber). Nylon is reinforced with glass fibre, which greatly enhances the hardness of the line and provides greater abrasion and heat resistance, with a tensile strength of more than 100 lbs, enabling it to maintain stable performance at high rotational speeds and not easily broken, thus ensuring the continuity and efficiency of the mowing operation.
• 【PRE-LOADED STRING TRIMMER SPOOLS】For home owners who need to use a string trimmer maybe once a week, replacing the spool beats winding nylon string on your old trimmer ! Just open the trimmer head and pop it in and you're good to go. Auto feed string trimmer refill reduces the hassle of manually tidying up spools. A must have for the trimmer
