If your DeWalt DWS779 or DWS780 miter saw has a broken or missing lower blade guard, this replacement part (N027988) is exactly what you need.
It's made to OEM specs, so it fits perfectly and functions just like the original – no modifications or guesswork.
The lower guard is a critical safety feature that covers the blade when it's not cutting, and retracts smoothly during operation to expose just what's needed.

This replacement restores that protection, so you can get back to cutting safely.
Construction is durable plastic that can take the occasional bump and kickback common on job sites.


Whether you're a contractor, framer, or DIY woodworker, having a working blade guard is non-negotiable for safety.
Don't risk using a saw without it.
