After communicating with fitness enthusiasts we found that fitness enthusiasts pay close attention to the comfort, safety and durability of the handle material. After nearly a year of changing materials and repeated testing, we finally developed this single D cork handle cable attachment. Lat pull down metal steel welding coat natural cork handles ergonomic design and horizontally inserted screw structure. It can withstand greater tension and improve the safety of exercise. Single D handle can reach more than 450Lb (Calculated by adult weight 400LB , the pull force needs 1.2 times, one-handed use is half of the weight). D-type handle fully meets the range of sports standards. D-handle barbell whole is made of stainless steel, and the surface has been plating treatment, because it is considered that the product may be used in an underground high temperature environment. The grip of the handle adopts a natural soft bag, which is environmentally friendly, has no peculiar smell and feels good in hand. It changes the burrs and rubbery smell you encountered before, giving you a completely different feeling. You can protect your hands from injury while enjoying fitness.
