Secure With The Touch Of A Button Hunter's new PowerSlide™ slip plate locking mechanism helps secure the rear wheel slip plates with the touch of a button. The PowerSlide slip plates automatically lock when the rack is lowered to the ground, preventing users from driving off the rack with the slip plates unsecured. The new slip plates have controls on the lift of the console, can lock or unlock plates with the touch of a button and have LED lights that indicate the current status as "Locked" or "Free". PowerSlide slip plates are available on newly purchased, select Hunter RX Scissor Racks.
