Abstract: This invention relates to novel constructions of rearward viewing devices consisting of extension arms and mounting attachment devices with convex marine mirrors for use by the operators of most modern watercraft having other than side to side dashboards or metal framed windshields. This invention provides for substantially 180 degree viewing behind the craft by the operator of such aforementioned craft for the purpose of rear vision for safety whether or not towing another craft or person or persons engaged in any water sport such as skiing, boarding, tubing, etc., when the operator is without another person on board as a legal spotter.

Abstract: According to the present invention impact damage to a mail box can be prevented entirely or at least minimized to the extent whereby the mail box can still function by enclosing the exterior surface of the mail box in a novel cage constructed of impact resistant material and adapted to be fastened to the mail box standard in such manner that any impact force applied to the cage is primarily transmitted from the cage to the mail box standard. The cage is further characterized by a flexural strength adequate to prevent it upon being subjected to an impact force from indenting or otherwise deforming the mail box surface to an extent preventing satisfactory opening and closing of the mail box door by U.S. Post Office personnel.
