Bsc Preferred 176-132 12 Inch Poly Miter Box

Product Description

The BSC PREFERRED 176-132 is a 12-inch polystyrene miter box designed for making accurate, repeatable crosscuts and angled cuts in wood trim, molding, and similar stock. Built from high-impact polystyrene, the box maintains its shape under repeated saw strokes without flexing or shifting. Three fixed cutting slots guide a handsaw at 45, 90, and 135 degrees, eliminating the need for a protractor or layout tools on straightforward cuts. An integrated ruler scale runs along the base for quick length measurement without repositioning the workpiece. This tool is a standard shop and jobsite aid used by carpenters, trim installers, and general tradespeople.

The 176-132 fits residential and light commercial trim work, staging, and temporary framing tasks where a power miter saw is unavailable or impractical. It is suited for cutting door casing, baseboard, chair rail, PVC trim, and similar profiles. The 12-inch capacity accommodates standard trim widths, and the fixed-angle slots are adequate for the most common cut angles encountered in finish work and rough carpentry alike.

Installation Notes

No power source or fasteners are required for setup. Secure the miter box to a stable work surface or clamp it to a sawhorse to prevent movement during cuts. Keep fingers clear of the saw slot openings at all times. Select a saw blade appropriate for the material being cut to maintain clean edges and extend the life of the box slots.
