The STANLEY 20-800 is an adjustable angle clamping miter box designed for precise crosscuts and angle cuts in trim, molding, and similar materials. At 22 inches in length and weighing 8 pounds, it provides a stable, rigid platform for guided hand-saw cuts. The adjustable angle feature allows the user to set a range of cutting angles beyond a fixed 45- or 90-degree stop, making it a practical shop or job-site tool for carpenters, finish tradespeople, and skilled DIYers who need repeatable cut angles without a power miter saw.
This miter box is suited for residential and light commercial finish work, including door and window casing, base molding, chair rail, and similar trim applications. The integrated clamping mechanism holds workpieces securely during the cut, reducing drift and improving cut quality. It is intended for use with a compatible hand saw and does not require a power source, making it portable and code-compliant in any work environment.
Designed for use with standard hand saws compatible with guided miter box applications; verify saw kerf width and spine depth against the box guide slots before use.
Secure the miter box to a workbench or stable surface before cutting to prevent movement. Always clamp the workpiece using the integrated clamp before beginning a cut — never freehand guide a saw through the slots. Keep hands clear of the saw path at all times. No electrical shutoff or permits are required for hand-tool operation.
