I'm working with 1 & 5/8" unistrut and trying to make a connection into a vertical fence post (essetially trying to make a frame). Is there an endcap or another solution to make a good tight fit. thanks
I'm planning a build a racking system (basically a fence for solar) similar to pictures below. For the vertical posts into the ground, i'm looking at a couple options:
1) u-channel galvanized post (this is 2 lb/foot, but could jump to 3 lb/foot if recommended)
2) square sign post
I'm using Unistrut/Superstrut and need to double up. I plan on joining the backs to create the rails on both sides. What is the best bolt size to join the two together? Should I use the 1/2 or 3/8 bolts? Do I use regular washers or the special square ones? How long should they be?
