Ergonomic router assembly
View Patent ↗An ergonomically designed router assembly includes a base assembly coupled with a motor casing including a grip assembly which provides an overall narrower profile to the router assembly. The grip assembly may relieves stress on the muscles and allows the operator to more securely grasp the router with one hand thus decreasing fatigue levels as compared to those routers which require both hands of the operator to be engaged for control over the router.
