Why do you need box link?
ATV is inconvenient for shipment? The motorcycle can't be fixed? The lawn mower is easy to move?
If you haul any kind of cargo, you will have to secure it with some kind of tie-downs - either straps, nets, tarps, or chains. And you will have to attach your tie-downs to anchor points on your truck or trailer. If you have no anchor points or lack convenient places to attach tie-downs, you can add these anchor points.
The tie down anchors compatible with multiple aftermarket accessories such as cargo dividers, tie-down cleats, bed extenders, stowable loading ramps and more!

How to install it?
1.Find the 4 tie down locations in the bed of the truck. (2 on each side)
2.Take your BoxLink cleat, unlock it, and line it up with the insert.
3.Pull out on the bottom of the cleat, and slide the top insert up into place.
4.Once in the desired position, use the special keys to lock the cleat into place.
