Abstract: The existing problem within the construction industry is that with each builder the framework for the project will differ based on the location of the supporting framework at the required distance, sometimes causing huge cost overages or poor quality workmanship. The solution to this problem is to ensure each ensuing supporting frame member (wood or metal 2×4, 2×6) is spaced exactly at the same distance as the previous frame member. This hand portable jig will ensure this occurs by setting the jig to the desired distance, then placing the jig where it straddles the last frame member installed, awaiting the insertion of the next frame member. Each newly installed frame member will be spaced at the same corresponding distance throughout the project. The Speed Stud and joist Setting Jig is my invention; it is unique because once the tool has been set to the desired distance one individual can consistently place wall studs or floor, ceiling joist into position and secure them into position.
