    摘要: A sports arena pad with beveled sides to create overlapping beveled joints when the pads are releasably attached to an arena wall in a linear side-by-side configuration. The inner padding is made of two layers of foam. The first layer is a low-density foam panel attached to and covering a front surface of a substantially rigid backing panel. The second layer is a high-density foam panel attached to and covering a front surface of the low-density foam panel. The padding and much of the backing panel is covered with a weather-resistant fabric, preferably by wrapping. Releasable fasteners are attached to the rear of the backing panel for attaching to complimentary fasteners on the arena wall. Special pads with one beveled edge may be provided for end pieces.
