A gas utility service saddle U-bolt installation holder comprises an elongated handle having a substantially L-shaped lower end and a clamp adapter attached to said L-shaped lower end for holding a U-bolt at a location substantially midway along its lengths with the U-bolt legs projecting upwardly so as to straddle a gas main from the underside of the main, the U-bolt clamp being channel-shaped to receive the U-bolt therein, and a thumb screw being provided through one of the upstanding legs of the channel shape to clamp the U-bolt against the opposite channel leg. Preferably, the U-bolt clamp is a separate clamp adapter having a pair of vertically spaced apart support arms by which it is mounted on conventional "lower tape holder" tool, using a second thumb screw to make such attachment. The method of using such a tool is described, involving positioning of the U-bolt beneath the gas main located within a deep, small-area excavation, with the legs of the U-bolt upright to receive a conventional crown saddle thereon.
