DRILL A 5/16th HOLE AND FIT THE SMALL SECONDARY LOCKING BOLT. (IMPORTANT NOTE: DRILLING THE HOLE ACCURATELY IS THE ONLY CRITICAL PART OF FITTING A BIGVEE, SO TAKE YOUR TIME AND BE PRECISE WITH THE LOCATION OF THE HOLE BEING DRILLED).
The secondary locking bolt goes through the BIGVEE™ flange and through the hole you drill in your trailers metal bow stopper support arm. Only one of the four pre-drilled holes in the flange will be used. Choose the most suitable hole for the bolt to locate within. The hole you choose will be the one most centrally located on your trailers bow stopper metal support arm.
Fit the small locking bolt from the inside with the nut on the outside.
