What is the process for filing a warranty claim on my Alu-Cab truck cap?

Send us photos of the issue, then provide the following so we can open a claim with Alu-Cab: the serial number (on a stamped tag above the driver's side door), where and when it was purchased, who installed it, and a copy of your invoice. Once Alu-Cab reviews the claim, we'll follow up with next steps.
