Avoid third party products. The U brackets that are supposed to slide into the channel didn't fit and needed to be hammered in. You shouldn't need to use a hammer on an engineered, metal product. That was the least of the problems. The U brackets is thick metal plate that is bent at a 90 degree angle. It has three holes with welded nuts to accept mounting bolts. As an engineer, I can see how the designers did not properly account for the bending radius which has the effect of shortening the leg of the piece in which the holes are drilled. The holes were likely drilled before bending. The end result is that when the bracket is finally banged into the channel, the holes to do not align with the slot in the rail assembly. Some do, some don't. Hence, you can not get all six mounting bolts to properly seat without grinding the assembly. Again, this shouldn't happen on an $800 engineered product. Very disappointing
