There are many reasons why Sherlock is one of the world's best-selling professional frames. The quick-release spring prevents roller slippage, yet allows clean, one-tap removal. Internal bearings keep the durable fibreglass-reinforced nylon cage spinning smoothly. All Sherlock frames also have a 90˚ chrome-plated 5/16" shank for control. The comfortable, full-size grip works perfectly with extension poles, including the Sherlock GT.
