All Alpha Stencils are available as frameless foils for mounting in Alpha Tetra and VectorGuard foil frames. Alpha are now taking this technology to a new level with the launch of ALPHA® Tetreabond™. ALPHA Tetrabond™ 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 Tetrabond™ 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.
