Why does the cover get stuck when sliding all the way out?

     Recently, we wanted to secure manual retractable tonneau covers' locks due to our carrier's mishandling during the shipping process, so we added protection to the locks. These lock protectors need to be appropriately removed before you start assembling the rails to the canister. Therefore, please make sure you remove the lock protectors first, otherwise, you will have a hard time putting assembling everything together, and will also get stuck when you sliding all the way out.  

     (This may apply to SyneTrac & SyneTrac-PRO)

     Besides lock protectors, another thing worth mention is about the placement of the keys. As part of the assembly process in the factory, the straps are wrapped around the keys to eliminate mistakes such as putting wrong keys with the wrong locks.
