5.
Wrap a piece of electrical tape around the drill bit, spaced 1-1/4” from the drill bit tip. This will act as a hole depth
indicator when you drill each pilot hole. Pilot holes should be drilled at least 1-1/4” deep. A little bit deeper is acceptable
but do not drill less than the required 1-1/4” depth.
6.
Drill 3/32 X 1-1/4” pilot holes through the lower holes in the U-channel’s sides, on both visible and not visible sides. Only
use the lower holes to anchor the floor 4x4s to the U-channels.
7.
Drive one ¼” X 1-1/4” lag screw through the pilot holes you drilled.
8.
Repeate steps 6 and 7 for the other side of both U-channels.
