Hoiked this in to the boot with the aid of a passing stranger and my O/H at one end.
We collected a 2 column one approx 1m x 800 a year or so ago which, being much taller, allowed for a little purchase so I could squat down, tilt it to one side and hug/lift it on to the boot on my own.
But this one being three columns, so short and much wider was near on impossible. I'm not weak either but functional strength pls respond.
The builders can get it out tomorrow
MDF/wood to slide and then ratchet straps to secure it down for the journey home.
