This is a clip system that allows you to mount to the front edge of the Rockpoint tables from this Amazon listing, I used it on the 60" long variant.
I specifically used it to mount the Brewhardware RIMS tube to the front. The mounting system uses M8 Bolts, the M8 head sinks into the backside of the Male clips and sticks forward. This can be used with anything that uses standard M8 Bolts.
Happy Printing
