The IFCW™ at Louisville Slugger Field has a length of over 770' and can be installed by a crew of 8 in less than 12 hours to a height varying from 5' to 8'. When the IFCW™ is needed, due to flood threat, it is erected....when things are normal, the invisible wall is stored away in the vault ready for future mobilization, and baseball fans are free to enjoy the grounds, have a hotdog and view the beautiful old railway station.
