4.Mark screw positions for front and rear connectors and
tape ¼" from drill tip to set drilling depth. Use care not to drill through tabletop.
5.Fasten front connectors to front edge of board as shown in Figure 2 using ¾" screws. Fasten screws half way. Do not fully tighten.
6.Assemble right rear connector as shown in Figure 3 and fasten to board. Select screw length based upon board thickness.* Fasten screws securely.
*For board thicknesses of 5/8" or less:
If your board is 5⁄8" thick or less please use the
5⁄8" screws in place of the ¾" screws as shown in Figures 3 and 4. Do not use ¾" screws included with hardware kit since they might break through bottom of board.
7.Assemble left rear connector as shown in Figure 4 and fasten to board. Fasten screws securely. Pulleys are designed to be tight fitting and do not spin freely.
