Normally I have made mine between 300 and 450mm deep. Yesterday I was at Direct aluminium looking for some tubing for HD tent poles and they had some offcuts of cool room coving so I bought them.
The short off-cut is the 70mm and just long enough to get a couple of anchors but the larger one is 110mm and 1340 long. I'm wondering if I should make 2 or use my normal length and get 3?
At the moment I am leaning towards making 2 longer ones just in case we get a lot of snow this white season but I can change my mind up until I make that first cut
I'm interested in peoples thoughts
