Devices such as disclosed in the subject invention find application in the installation of ceiling tiles and other building materials usually attached to overhead rafters and ceiling beams. Prior art devices have been cumbersome and/or complicated and expensive and most have required at least two operators in order to effectuate a fine adjustment of the holding device. The present invention provides fine adjustment capabilities requiring the attention of only one operator.
