Hello all ROb here with another video on one of my latest projects. I installed a electric gate opener on our 20 foot cantilever sliding gate. I bought the Sliding gate opener SL600AC (L) for under 200 bucks it was a really low cost sliding gate opener and pretty simple to install. This is going to be a 3 part video on installing the SL600AC(L) sliding gate operator. It makes a HUGE difference with the electric gate opener.
Thanks for watching,
