Thank you for your detailed review!
We're glad to hear you found the crossbar sturdy, well made, and securely packaged, and that you're happy with the overall quality and fit.
We also appreciate your constructive feedback regarding the rubber T-track strips and installation instructions. Your comments about clarity in the manual and the additional adjustment components are very helpful, and we'll pass this along to our product and documentation teams for improvement. We’ll also note your suggestion regarding offering black clamp pieces for a more uniform look.
