NO UPRIGHTS. You are buying a single shelf with two support cross-members only. Uprights are available elsewhere from other suppliers. I can give you the contact details of a local supplier who I have pointed others to in the past. They charge around £100 per upright if it helps. I am only selling multiples of single shelves. They are in very good condition; lightly used. The shelves work alongside APEX UK6 racking system adding expansion and flexibility. The 2 support cross-members are made from galvanised steel. Heavy duty chipboard 2.5cm Thick, 79cm Width, 50cm Depth. BULK BUY OFFER: Buy 10 shelves and you will be supplied with 12 (ideal for three 4 tier bays). Collection only from Greenwich SE8 London
