Camera Lens Boards
If you need to replace or find a new lens board, doing a quick search of camera lens boards will give you plenty of options. To get the right product for you, it's easiest to look at your options by the now universally accepted copal number, giving you standard sizes to work from.
Brands like Sinar, MPP, Linhof and Arca-Swiss are popular, but you can also find plenty of unbranded products. You can also shop new or used to suit your particular needs and budget.
