I purchased these to protect my RV shore power cable and fresh water hose while my RV is parked and powered up in my driveway. These offer the protection I was looking for. A contractor has been working in my driveway and has the need for driving a small tractor up and down the drive. These covers easliy handle the tractor weight, even when the bucket is filled with stone for a retaining wall. I would recommend these to anyone with the need for protecting cables/hoses from vehicle traffic.
