Pittsburgh – – September 18, 2026 -- A California-based inventor has developed a patent-pending tool called the V-SQUARE designed to help builders square vertical members quickly and accurately when framing openings for doors and windows.
Tool measures two distances simultaneously to speed up framing work
The adjustable device allows users to measure two distances at once, cutting the time needed to create consistent square openings for vertical members. The inventor, from La Mirada, Calif., said the design targets builders who need a fast and accurate way to install vertical members where a uniform square opening or space is required.
