R & R Tackle M2/3 Set is a “Micro Mini Set of three graduated release clips for kitefishing, especially in light wind conditions when the weight of the clip is a critical factor to success. R & R M2 clips wont weigh your kite line down like other heavier clips which may result in your kite line bowing or falling into the water. The M2 release adjustment is quite precise, consistent and provides a smooth reliable release of your kitefishing ring. Best when used with R & Rs 9 mm highly polished, rounded Stainless Steel Rings. Made in the USA.
