Trend CRB Combination Multi Function Router Base

The Trend CRB Combination Multi Function Router Base is a retro-fit, quick-change router accessory designed to significantly extend the versatility of your existing router without the need for multiple dedicated jigs.

Engineered for professional joiners, carpenters, and serious woodworkers, the CRB performs seven distinct functions from a single base unit. These include an offset baseplate, router compass, adjustable trenching guide, anti-tilt support, mortising guide, false panel groove copier, and compatibility as an anti-tilt device within the Varijig frame system. This breadth of functionality reduces setup time between tasks and eliminates the need to store numerous hand-made jigs.

The compass function covers a radius range of 19mm to 224mm, while the mortising guide accommodates timber widths from 50mm to 200mm. The trenching guide features 40mm of micro-adjustment for precise, repeatable cuts. For larger circle work, optional extension rods (ref. N/COMPASS/AEX) are available to increase the radius further. An accessory edge trimming base (ref. CRB/TB) is also available for trimming lipping up to 16mm wide with a 6mm projection.

The CRB is compatible with most routers fitted with two fence rod holes at centres of 78mm to 130mm, accepting 8mm, 10mm, and 12mm diameter rods. The included bridge shim pack allows fine adjustment to ensure the baseplate sits perfectly flat, improving finish quality and precision on every routing pass.
