One of my torsion springs broke and after several calls, no one was willing to manufacture me a new one and allow me to install it. Every company told me that they were very dangerous and their service technician needed to come out. One company even told me that by law, he is not allowed to sell the springs to the public. Spoke with Mark and another gentleman working there and by the end of the next day my spring was ready along with advice on how to install. Job took 30 mins.
