Do you and your friends love cozy rounds of darts? To ensure your fun isn't spoiled by holes in the wall and scratches on the floor, this square catch ring is here to help. The catch ring for dartboards with a diameter of about 45 cm comes in 4 pieces that can be easily assembled. If a throw goes wide of the dartboard, the darts will stick in the 3 cm thick wall protector. The impact holes are barely visible after the game.
