Foster Supply Fabricates bat gates in house along with providing the HDPE pipe that they are placed in. We sell 36", 42", 48" and any custom modifications you could need. We have become very efficient with the fabrication of these gates and can provide the best prices out there. As long as we are provided a drawing we can make whatever size bat gate is needed to cover the mine entrance. We are also able to divide the gates up into manageable weights in the instance that equipment can't access the site.
