Lifelines Door Anchor is an essential part of any cable system. By anchoring something other than your body, you can change the angle of resistance and drastically increase the number of exercises you can perform with your fitness cables. The heavy-duty, self-centering, Door Anchor protects cables from regular wear and tear and holds up to three cables at a time in order to provide customized workouts! The Door Anchor allows the resistance point to move up and down the door to change the angle of resistance allowing for total body exercises. Set it high for downward movements, set it low for upward movements, or center it for presses and rows!
