Roll Up Door Header plate
Note- This headers plate is only necessary on a 7' wide roll-up door. If you're taking off the cargo doors and putting in a 7' roll-up door, you will definitely need this.
Header plates, sometimes referred to as "top end rails", are plates that protect the roll up door barrel and cap everything off to prevent weather from getting into your container. You will weld this to the top and side of your container.
A must-have for a 7' wide Shipping Container Roll Up Door
