sill cap

Thank you for reaching out to us! We're not familiar with what a sill cap is in this instance but I see that you were looking at the 80-102. This is a track cover for patio glass doors. Is that what you're looking for? If not, can you show us a photo of the hardware in question?

Please note, we aren't able to ship anything as long as 102". 

The 80-102 is the only track cover we sell. What you could do is purchase two, butt them together, and then cut off the excess to match the needed length.
