An adjustable support tool for either vertical or horizontal mounting. The adjustable support tool comprises a rod slidably received by a tube. The rod has depressions formed thereon. A threaded portion is coupled to the tube and a hand grip tightener is turnable engaged to the threaded portion for adjusting their overall length. A ratchet housing is resiliently engaged to the hand grip tightener. The ratchet housing has a ratchet for securerly engaging to one of the depressions, a wheel spring for rollably engaging to another one of the depressions, a safety lock pivotally engaged to the ratchet housing for prevent access to the ratchet when locked. When the rod is slided, the wheel spring pushes up the ratchet from its underside to loosen its engagement. The loosened ratchet allows the rod to slide more smoothly, while protecting the painted surface on the rod. Both the ratchet and threaded portion provide adjustment to the overall length of the support tool. |
