the blocks are 4"x5.5" (same as a HD) but only 1/2" thick
barb holes go down each side.. and are connected across by 4 parallel channels.
also note that the pics show barbs soldered in... that is because of the odd way of attaching 1/2" barbs to a 1/2" block =) (need to make a slightly larger hole, then grind down the threads, then solder in the barbs. (i dont do this
)
3/8" barbs attach normally (tapped then twisted in, and teflon sealant)
bring your own mount
