Abstract: A paint spray gun is locked into a receptacle at the free end of a tubular arm pivoted at one end of an elongated tubular stock. The spray gun trigger is engaged by an operating finger, spring-biased toward the `off` position, which is operated by means of a sheathed, flexible cable through an operating lever mounted at the end of the stock farthest from spray gun receptacle. The relative angular position of the receptacle-bearing arm and the stock is adjustable. A quick-release receptacle is provided to permit the removal and reassembly of the spray gun to the extension arm with facility.
