Some routers can be difficult to match up with suitable guide bushes and a universal sub-base can be the only solution. A round base can be preferable in many circumstances too. The UJK Technology sub-base is precision machined from aluminium and fitted with a low friction surface for ease of use. It is designed to accept standard UJK Technology guide bushes and holes for these are drilled with an M4 thread. It is also designed for mounting to a very wide range of different routers including Bosch, Makita, Elu, Dewalt, Festool, Trend, Ryobi and Hitachi models to name a few. 176mm diameter x 7mm thickness. Requires the addition of the fixing kit (508626).-bg
