Original Makita replacement Box Cover (part number 158378-6) — a complete feed/box cover assembly for Makita autofeed screwdrivers. This part restores the outer feed/guide housing so the feeder and screw track are enclosed and aligned again, and is supplied as the complete cover assembly used on Makita autofeed screwdrivers.
Fits example models such as BFR750 and BFR750Z, and is listed for use on DFR750 and the 6843/6844 / BFR5 series (models often shown together in the DFR/BFR exploded parts lists). If your tool uses the Makita autofeed cassette/box assembly and the outer box cover is cracked or missing, this original Makita replacement will match the factory part.
Simple swap-in replacement: the item is the complete box/cover component shown in the official parts diagrams, so you’ll reinstall it into the same mounting location as the original cover. Makita parts are built to the original fit and function for a clean, reliable repair.
What you get: the original Makita 158378-6 box cover assembly sized to fit the feeder/guide area on the models above — a direct-fit replacement that returns the tool’s feeding system to a protected, serviceable condition.
