3pc Portable Base Assembly (Applies to both base sizes)
Please see Table 2 in Appendix A for 3pc Portable Base compatibility.
The davit base legs are shipped in a different orientation to optimize packaging and storage when not in use, Figure 15. To assemble, the
legs must be rotated from the packed position to the proper orientation for use. On both legs, remove the detent pins as shown in
Figure 16. Rotate the round tube of the leg to the use position, as shown in Figure 17. Align the holes of the round tubes and reinsert
the detent pins, as shown in Figure 18.

Before inserting the legs into the base center section, refer to the table in Figure 19 to match the Base Position with the Pin Position of
the Davit Arm. To install the Davit Base Legs, ensure the red thumb screws are loosened (turn counter-clockwise). Insert the legs into the
base center section and determine the offset your application requires; align the holes and insert the detent pins, Figure 20. Tighten the
red thumb screws (clockwise) to ensure they are locked in place as shown in Figure 21.
