LEGS ON A BASE CABINET
The Akurum black plastic leg bases have pegs/tabs on them that go into the holes in the bottom of the base cabinets.
You can use the leg under the corner of one cabinet or you can have two cabinets share a leg. The leg is just pushed into the leg base.
If the leg goes under one cabinet, you need to use the plate that transfers the weight of the cabinet from the side panel to the leg.
If two cabinets share a leg, the leg base itself supports the side and the additional plate is unnecessary.
The pegs hold the leg plate in place. However if you'll be moving the cabinet much, it's good to screw it in just so it doesn't fall out. The base is 3/4" thick so a 5/8" screw works fine.
LEGS ON A 12"D WALL CABINET (Used as a shallow base)
If you want to put legs on a 12"D wall cabinet to use it as a base, you don't need to drill holes for the pegs, just cut the pegs off.
To figure placement, I measured the distance from the front of the cabinet to the leg plate on a regular base cabinet (2 13/16").
Then screw the leg plate into place. Two screws are required so it doesn't twist around.
Leg on one cab:
Leg shared between two cabs:
I hung the wall-as-base cabs from the suspension rail so I only had the legs in the front to have somewhere to attach the toekick/plinth.
