The mounts shown in Figure 1-3, available from Precision Matthews, allow leveling adjustment from above. If installing on the PM1228 stand, 8 leveling mounts are required — 4 for the left hand cabinet, 4 for the right. Because there is insufficient headroom in the stand pockets, the threaded stems need to be shortened by about 1-1/2”. Before installing, oil the threads in each mount then bottom the stem (8 mm wrench) to be sure the pressure plate is able to expand the molded base. If necessary use a strap wrench to stop the cup from rotating. Place the cup under the stand, with washer and locknut above the stand footplate. Because an 8 mm wrench has only a small amount of leverage, it may be more convenient to replace the threaded stems with hex head screws (M12 x 1.75). Screw length should be 50 mm, but 45 mm (even 40 mm) will do if the floor is reasonably level. Adjust using a 19 mm or 3/4” ratcheting wrench.
