Great for. Recommend swapping set screws out for longer ones.
Works great and fits like a glove. Would recommend providing install instructions for less mechanically inclined individuals and definitely switching to MUCH longer set screws.

Heavy duty, super stretchy, and keeps everything secure!
I am impressed with this truck bed cargo net. It stretches incredibly well to cover full loads, but snaps back into shape perfectly without sagging. The elastic mesh is thick and feels very durable.
The included hooks are sturdy and make it super easy to anchor down to the truck bed tie-downs in just a few seconds. I’ve used it for groceries, camping gear, and loose boxes on the highway, and absolutely nothing shifts or flies out. If you want peace of mind while driving your truck, this organizer is a must-have. Highly recommended!
