Original DeWalt lower guard assembly N378852 — a replacement lower blade guard made from durable metal (aluminum-style) designed for DeWalt 184 mm circular saws.

This original DeWalt part restores proper blade coverage and the guard pivot/contact area so your saw’s kickback and debris protection work as intended; it replaces the older N152743 reference used on earlier runs.

Example compatible models include DWE575, DWE575SB, DWE574, DCS570 (and DCS570P1/P2 variants), and DCS574 series saws — suitable for the 184 mm class of DeWalt circular saws.

Physical Size: 196 × 137 × 42 mm (length × width × depth) — sold as the single lower guard assembly and ready to bolt into the original mounting points to get your saw back in service.

If you need a reliable, original DeWalt replacement to finish a repair, this N378852 lower guard is a direct-fit option from the parts for power tools lineup made for those DeWalt circular saw models.
