The UJK Technology mitre slot bar is a solid aluminium section designed to fit the standard 19mm mitre slot in your machine table. Overall dimensions are 457 x 9.5 x 19mm wide. There are four grub screws spaced equally along the length of the bar to fine tune the sliding fit of the bar in your machine table slot. Three M6 x 1.0 threaded holes are spaced equidistant along the length to accommodate any jigs and fixtures that you wish to attach. A very useful accessory for either saw tables or router tables where jigs for repeated operations help to speed up the production of machined components. N.B. M6 x 1.0 bolts will need to be sourced separately.
