The tach another member posted it so I figured Id get one,it works like a charm and easy to install.The box I need for work because of the equipment I carry to read water meters.The box hold my equipment just fine and a few bottles of water and my tools. It also had a place for a pad lock which is good for the area I read a lot of gangs.My equipment cost more then my bike so I dont have to worry about my bike lol
