346357-8 supersedes older part numbers: 346006-7
Genuine Makita under-driver guide — part 346357-8 — a direct-fit replacement for the driver assembly on Makita GN900-series gas framing nailers (GN900, GN900S / GN900SE).
Precision-formed to locate the driver/barrel correctly, this guide restores straight nail seating and smooth driving action when the original guide is worn, cracked, or bent. It installs into the existing mounting points of the GN900 and is supplied as the single guide piece you need to bring the driver back into spec.
Ideal for repairs and maintenance, this genuine Makita part is a small but critical component that prevents misfeeds and premature wear elsewhere in the driver assembly — a smart choice if you want to keep your framing nailer performing to factory tolerances. Makita parts like this one are built to the same fit and finish as the original tool components.
