Twenty-seven years ago, when I was working with a framing crew in South Denver, we would frame walls on the subfloor. Then, to save time, we sheathed them while they still lay on the deck; installed the windows, exterior trim, and siding; applied the soffit "ladder"; and nailed the soffit plywood in place. With all this material, these walls were heavy. So, to lift them into place, we used Proctor Wall Jacks (Proctor Products Co., 210 8th St. South, Kirkland, WA 98083; 206/822-9296). I recently had an opportunity to try Proctor Wall Jacks again with my crew. We used two 16-foot jacks — each rated at 1,000 pounds — to raise walls and lift beams into place.
