ALVIN® Professional Acrylic Triangles

Will not discolor or warp with age and handling. The machined finish and hand polished edges of the C Series (clear) and F Series (fluorescent) meet or exceed government specifications. The F Series is extremely popular because the refracted light has an illuminating effect on the drawing by accentuating the triangle’s edge. All models feature a double-taper cutout center for quick, easy lifting from any angle.
