Following the correct assembly of the oars, the pin-type oarlocks may be fitted to permanently attached oar lock bases as shown in the illustration:

Fully seat the oarlock into the sleeve portion of the base by aligning the flat portion of the oarlock pin, and the fixed pin within the sleeve of the base. When fully seated in the base, rotate the oar assembly 180 degrees to lock the oar into position. After correct assembly, the oar and pin-type oarlock will not pull out of the oarlock base. Disassembly of the oars and oarlocks is performed in the reversed order.
