Sub Fence Construction & Attachment

Sub fence dimensions diagram — 34.25mm and 13.00mm hole spacing, M6 nut location, max thickness 20mm

If needed, users can make and utilize sub-fences for additional support. You can secure the sub-fence onto the aluminum fence body of the MG-36/MG-36PRO by using a countersunk head screw and rectangular nut. We recommend using at least 6 sets of screws and nuts for securing the sub-fence.

Hole spacing: 34.25 mm / 13.00 mm

Fastener: M6 Nut

Max sub-fence thickness: 20 mm

The hardware required for sub-fence attachment can be sourced from the McMaster-Carr links above, or purchased from any compatible supplier. See the M6 hardware reference links at the top of this article.

Adjusting the Flip Stop Height
