Abstract
An elongated trough is slidably located on a vertically pivoted trough to carry pipe from a derrick floor to a pipe rack when there is little or no height differential between the derrick floor and the pipe rack. The slidable trough may be removed when the height differential is such that pipe will slide down the vertically pivoted trough by gravity.
