#genuinevblocks are machined from 6061 aluminum with a type II anodize. The gold version are for tables with 5/8" holes.
They utilize a 1/2'-13 set screw and feature approximately 1.125" of overall adjustment. The lower peg has a threaded through hole so there is zero table interference. Swap the set screw for whatever length you need at any time.
The v-block can be used with or without the lower peg. It has the same 5/8" diamter shoulder for a secure fit.
