Purchasing DIN Rail Parts
 

To save weight, my team has decided to only put as many of the red/black blocks as we need on the DIN rail and cut the yellow center jumpers that connect the blocks, but the cutting isn't exactly reversable. While we don't expect to need any more of the red/black blocks, it would be nice to know where we can buy new center jumpers in case of a design change. So, does anyone know a good place?
