ezc – easy centerline layout & joinery check tool

the ezc (easy centerline) layout tool is the first and only tool designed specifically for centerline layout in timber framing.

traditionally, establishing centerlines means repeated measuring, marking, and checking — a process that slows down even experienced framers. the ezc eliminates that hassle. with one simple, precise tool you can:

establish accurate centerlines quickly and repeatably
check tenon width for fit
verify shoulder height for clean seating
confirm squareness of joinery before assembly

by combining layout and joinery checks in one rugged tool, the ezc saves substantial time compared to traditional methodology — and helps prevent costly errors in the shop and on site.
