The streamlined design of these new cradles fit the body of a collector/controller snugly with simple, comfortable locking on the bottom of the cradle. The new design utilizes an ‘anti-crush’ feature that locks up the cradle when tight, but is limited — the risk of damaging controller is greatly reduced. These cradles are constructed of corrosion-resistant anodized aluminum and the stainless steel clamp screws feature non-jamming coarse threads for easy open and close use.
