The Jumbo-Koter Shergrip handle has a smaller diameter, making it easier to hold. It weighs less than the Wooster professional grip, and therefore causes less fatigue. The two-part construction incorporates durable "Sherlock green" polypropylene and black elastomeric material for better grip. Sherlock GT pole compatible. The new Shergrip frame works with both 4½" and 6½" Jumbo-Koter minirollers.
