There isn't a way to get the Slide topper without the rail, so you would need to get the full kit:
- Solera RV Slide-Out Awning - 13'1" Wide # LCV000168109
This will fit slides that have a flange-to-flange measurement of 152" to 157" wide. I did want to mention, just to cover all the bases, that if you were referring to your trailer coming with the Solera pre-installed brackets, and not the rail, you would still need the full awning kit, but you would also need the Solera Slide Topper... view full answer...
