Don't be caught without a versatile 5-Way Trim Guide in your tool box. These tools measure 10" wide and can be used to give you an ideal trim guide for flat glass applications leaving a perfect 1/16'-1/8" micro-edge. You can also wrap the edge in a paper towel and use this tool to "bump" the edges of the installed film to get that last bit of mounting solution out. Finally, this handy tool features a variety of angles and shapes that can be used as a template for cutting.
