The present invention allows for the connection of multiple sections of drill pipe in a mouse hole by securing a given section of pipe in the hole and delivering a rotational force to secure that pipe section to another section of drill pipe placed above it over the mouse hole. In some embodiments, the rotational force may be provided by the support unit of the present invention. In alternative embodiments, the rotational force may be provided by an outside source such as an iron roughneck, with the support unit of the present invention holding the drill pipe section in a stationary position as such force is delivered. The unit then allows the connected pipe sections to be lowered and secured so the process can be repeated to connect multiple sections of drill pipe together in the mouse hole. The multiple sections of drill pipe may then be retrieved as a unit, and attached to the pipe string already being used to drill the well.
