Right, if the
Coin Meters are back to back you use one vault for 2 bays,
The round safe and head are about $530.00 I have 4 for my eight bays. I much prefer the drawer type which I have in the Coleman islands. Much easier to pull and dump even though I have sleeves in the round ones. The square one from KR are $476.00 But I use an added layer of protection for both. I have a collar on the safe heads for the round ones with a hockey puck
lock, and the high security cover with the hockey puck
lock for the Colemans. Ra
Lock offers this.

If you are building new, and in a freezing climate I would try to run a line from the
coin box heater terminals to the vault with another heat strip. . Being out in cold weather with a torch in each hand is not fun.
