I am assembling some MFI wardrobes. MFI used to supply the back panel in two separate sheets and also gave you a plastic "H" shape strip to join the two panels together. However, now the back panel comes in one piece and it is folded up. The joint is so thin that I split the panel into two separate halves this evening.
Where can I buy the plastic "H" shape strip for joining (or holding) two roughly 5mm thick panels?
Thanks.
