This compact miter box includes straight and 45 angles needed by flooring installers, and really saves space in the tool box! The nickel-plated steel guides are highly accurate and case-hardened to resist wear even when used with a hacksaw. The wood base allows clean cuts through aluminum trim materials without dulling the hacksaw blade. Base includes synthetic rubber non-slip pad which helps the tool stay put in use and wont mark when placed on most surfaces.
