One-piece reversible flex holder with calibrated retention, for flexible face signs and tarp buildings

A one-piece reversible flex holder for retaining a flexible face material to sign frames and tarp buildings, comprising:

• a latch block;
• a latch blade mounted to said latch block by a hinge;
• said latch blade being configured to bend about said hinge over said flexible face material and to engage said latch blade to said latch block for retaining said flexible material between said latch blade and said latch block;
• said hinge being mounted along a plane of said latch blade;
• said hinge having a bendable segment therein and said bendable segment being calibrated to deform under a pre-determined loading in said flexible face material along said plane of said latch blade, for releasing an engagement of the latch blade and said latch block, and releasing said flexible face material therefrom;
• said hinge comprising a S-shape and said bendable segment being part of said S-shape and forming a diagonal of said S-shape, relative to said plane of said latch blade and wherein said bendable segment is bendable toward a perpendicular position alignment relative to said plane of said latch blade.
