Turn your Powerline squat rack into a versatile, multi purpose workout station with the Powerline lat attachment. The carriage on this attachment accepts one inch (standard) OR two inch (Olympic) plates. Build a wide, strong back without sacrificing either the space in your workout room or money to get a separate lat machine. The Powerline lat attachment is also good for bicep exercises and tricep exercises. This attachment is only for use with the PPR200x power rack by body solid. This is an attachment so it can not be used by itself.
