B&B Controls installs and maintains security gates for airports, military bases, banks, and other large institutions. On average, a gate can operate for 82 days before needing routine maintenance. B&B Controls institutes a new design in its gates that is intended to increase the average number of days that a gate will operate before needing maintenance.
