Alpha Tetreabond is the culmination of “frameless” stencil development; an elegantly simple system designed to enhance the rigidity of the foil, making safe mounting and demounting an easier proposition. Innovatively encompassed in a thin, one piece aluminum extrusion, Alpha Tetreabond stencil foils are designed for use with Tetra and VectorGuard foil tensioning frames and are backward compatible with the majority of frames currently in the market. They are available with all Alpha stencil technologies (Alpha Cut, Alpha Nickel-Cut and Alpha Form) to suit the majority of printer size requirements.
