The CRB7 Edging Trim Kit is designed to work with the MPower CRB7 Multi-Function Router Base
(45924, sold separately). Together, they give you the ability to trim solid wood edging or edging tape without having to balance your router on the narrow edge of the material. Instead, the edging trim kit includes a bearing guide that runs against the narrow edge, while the router bit is moved up and down to adjust the depth of cut, according to how close you would like to trim. This allows extremely close trimming of edging, which means minimal sanding.
