How To (?) : Mounting Multiboard on Elfa Vertical Hang Standards

UPDATE: Solved!
UPDATE2: Revised to use 1/2” threaded rod instead of 1/4”. Tried also 3/8.. but decided the rigidity of 1/2” would pay off (3/8 has about 1/5 the deflection of 1/4… and ½ has about 1/3 the deflection of 3/8”)

Still working through this… not seen another solution yet… curious about community thoughts…

I already have Elfa vertical standards throughout my garage… mostly w/ shelving, but some blank spots. Looking to do some tool storage. Had the idea of mounting threaded rod between standards.. then hanging the multiboard on the rods… I made a clip to affix the rod to the standards.. now thinking about how I might mount the board to the rod… I thought perhaps a bolt w/ a hole in it to pass the rod through?  But that would require the board to be assembled when it’s hung.

any ideas? As I’m writing this…  another thought.. perhaps a mod to the snaps…
