The Curb Box Locking Device from INNER-TITE is designed to prevent unauthorized access to curb boxes. The Curb Box Locking Device does not require any tools to install; simply lower the proper size device into the curb box using the Curb Box Lock Key. Attempts to remove the device will cause the claws to engage the side walls of the curb box, preventing removal. The Curb Box Lock Key for removing the device is sold separately.
