Pivotrim Rino Tuff Universal Hybrid String and Bladed Trimmer Head Replacement Whether you?re working professional landscaping or want to keep your home tidy, you want to optimize your trimming head system. Sometimes, you?ll need to use blades for tougher applications in a more wild environment. Other times, you?ll want to use string to hack through a wide area of thin grasses. With Rino-Tuff?s Pivotrim system, you?ll be able to have your cake and eat it, too! This unit has slots to insert string and blades, allowing you to quickly swap between the two in record time. Keep them attached at the same time if you want to; the choice is yours! This unit accepts 0.095? string, with pieces readily available for you to string up your system right away. If you want to use different brands, though, that option is open to you. Installation is a breeze. You can plug this into most any gas trimmer by unscrewing the previous head and screwing this one in. It comes with adaptor pieces, so it will most likely fit your unit (brands listed in bullets). This piece packs more value than standard trimmer heads. The unique string compartment design swivels upon sharp impacts with concrete or fencing materials, a feature that keeps your line lasting longer than it would on traditional heads.
