Review on 🚣 High-Quality 2 Pairs Kayak Rack J-Bar Car Roof Rack with Tie-Down Straps for Canoe, SUP, and Surfboard Mounting on Car, SUV, and Truck Crossbar by Paul Barnes

Significantly cheaper than comparable J Hooks. Easy enough to assemble. My crossbars are actually ladder racks so I had to buy 8 longer stainless steel carriage bolts and 16 stainless steel nuts, but my bars are a legal 2" and that's not normal usage. When the yaks are on, they stay put. They want to rotate when empty, regardless of bolt torque. (The bars are also perfectly round). I can drill holes through the J hook plates and the bars putting rubber underneath doesn't make them any sturdier. But generally the racks are on the trailer and most of the time they have yaks on them and they're fine.
