Door and window openings in masonry construction need to stay straight through the pour — and without soldiers, the opening shifts as the masonry settles and cures, costing you callbacks and expensive remediation work. Dura-Taf Soldiers are the full-height PVC profiles that hold the opening geometry through the entire masonry cycle. 18.5-in length covers the full height of most standard door and window openings in new masonry. Rigid PVC profile will not rot, rust, or warp like wood — and the full-length geometry maintains the opening straight through the pour and cure cycle without deformation. The same soldiers stocked at Crofton Lumber that masonry crews across northeast Nebraska and northwest Iowa have made standard practice on brick ledge flashing jobs.
