I have a large garden shed which I seemed to dump everything and anything in resulting in me not being able to find anything when I needed it.. After checking for shelving which was robust and easily assembled, I decided Gorilla Racking fitted the bill. Oh and how it fitted the bill. Yes it does suggest two people to assemble but I did it alone and although not easy by the time I assembled number four, it was so simple. I will be ordering another two shelving systems in April ( shed in two parts, one large and one smaller part).. Fantastic service and an excellent product... If you are thinking of buying, this product does what it says on the tin...
