SKU: R1174 Optima Dual Battery Box, Lengthwise
We are very particular about how these go together because we see so many broken and cracked weld battery hold downs, and most of the broken ones weren't cheap either. The real problem we have found with the easily broken ones was multiple welds on too thin material, some are only 20 gauge, and they simply can't take the vibration.
Each battery has a hold down in the shape of the newer battery top (if you have an older Optimas they will still fit). We do not pre-drill any holes for mounting because you will want to mount them for YOUR vehicle and not have to work around someone else's idea of what is right. They can be bolted or welded in but remember that batteries are heavy.The dimensions of this box are 20" X 7 1/8".
