What is the Diameter of the Inner Tube and is it Hollow on Rhino-Rack Ladder Roller RR1375
Question:
From the diagrams it appears the ladder roller rack attachment has either built in bearings in the ends of the tube or a sleeve that fits over the mounting unit/bearings. In either case the roller tube has a hole in each end. 2 questions: 1. what is the internal diameter of the hole in the tube? 2. Is the tube hollow all the way through? Thanks

I went out to the warehouse and pulled a Rhino-Rack ladder roller, # RR1375, to take the measurements for you. The internal diameter of the steel piece is 1.4 inches. The outer diameter of that same piece is 1.7 inches.
The outer tube is 1.75 inches inner and 1.95 inches outer. They are both hollow all the way through.
