Another possibility is to use the standardized terminals from Keystone that you can buy from Mouser.
see 534-1502-1 (solid) and 534-1540-2 (hollow).
Essentially you build your own terminal strip which allows you to place the turrets where you want them. I usually cut off a strip of polycarbonate the size I need, drill the holes where I want them and then put in the turrets with the staking tool (and a hammer).
The turrets are not that expensive, but you do need to buy the staking tools 534-tl-2 or 534-tl-5
