Figure 4. Configuration for 6” bolts.
3. Mount adjustable pulley brackets. When shipped, the adjustable pulley brackets
look like the ones shown in Figure 5. The bolts need to be removed and the bracket
needs to be positioned so that the top of the bracket is in the top hole as shown by
the arrow in Figure 5. Use a 3” bolt with flat washers, end cap washers and end caps.
When you remove the bolts, leave the pulley bolt and pulley out since you will need to
thread the cable with the pulley removed.
