The York Preacher Curl Attachment is compatible with the York 530 and 540 weight benches. It enables the user to perform bicep preacher curls without purchasing a separate machine. Preacher curls can be performed with dumbbells, barbells or EZ curl bars to isolate the bicep for great results. The York curl attachment simply clicks into the bench and tightens. It is height adjustable to suit and features a well padded foam absorbent arm pad for comfort. Bench not included.
