The Security Cap is an excellent tool for containing snakes. It fits on any 5-gallon bucket. The Security Cap has a clear lockable door for added security. Curious onlookers may see the snakes and the key may be removed and placed in a secure location to deter accidental removal of snakes. The Security Cap is not designed to be a permanent snake habitat. It is designed for temporary snake containment. The lid has a collar that fits on a 5-gallon bucket. Once the collar is properly seated the lid screws onto the collar. The Security Cap has a clear door with a locking mechanism and several small holes for ventilation.
