Help prevent line ducking and keep small children in order with Visiontron's Retracta-Belt Dual Line Post with Black Scuff-Proof Base. The heavy-duty belts easily extend at two levels, giving you extra security. Since the belts retract into the post, there are no extra pieces to store and carry. Comes with a black ABS cover that won't show scuff marks. Choose from several post types, belt colors and for indoor or outdoor use.
