Automatically calculate header sizes, prop counts, couplers, and rental durations. Built specifically for masonry subcontractors.
Enter your opening width and height and the system determines header lengths, prop spacing, coupler counts, and rental timelines based on real jobsite rules.
This tool is based on the same logic we use in the field: spacing props every 6 feet, combining headers into 12-foot sections, and matching rental durations to total span.
Generate clean PDFs for rentals, pick lists, or foreman handoff. Everything is designed to save time at the yard and on the job.
