Tolerances/Allowable Deviations from Assigned Dimensions - All silicone, thin silicone and polycarbonate products are subject to our standard manufacturing practices which generally carry expected tolerances in the finished product. An acceptable tolerance of deviation from engineered values should be considered as follows; Platinum Silicone +/-2.5% of assigned dimensions. Injection Molded/Thin Silicone +/- 2.5% of assigned dimensions. Polycarbonate Plastic +/- 2.5% of assigned dimensions. Bold Maker will endeavor to manufacture products based on assigned dimensions, subject to the aforementioned tolerances above.
