Rubber made plastic box re-enforcement.

[mr_modify1]

I have used these plastic boxes for 15 years and every year I throw at least one away. I don't think they were designed to take the punishment I give them. They have to take lots of weight and stand up to the cold weather. The problem is too much bending that causes cracking usually on the top rail and at the corners. I want to share the solution with you as it has made a fantastic difference to the situation. Adding the pool noodle just makes them easy to carry.
