Abstract: Due to the inherent design characteristics of a portable gas cylinder, such as narrow base and high center of gravity, complicated by the environment in which they are most commonly found makes them particularly susceptible to being knocked over or dropped. This occurrence usually precludes regulator and gauge damage, resulting in time consuming and costly repairs. The present invention provides a novel means of providing protection to a regulator and its gauges in a manner that is not time consuming to attach, cumbersome to handle, nor obstructs or restricts the operation of the regulator and its gauges.As an added benefit, the regulator guard provides by virtue of its design a convenient and safe handle by which to carry the cylinder.
