Pushing Vinyl Bu;b weatherstrip

Is your 58-173 Pushin Vinyl Bulb weatherstrip available in 94 inch lengths for taller doors? If not can it be spliced effectively or can you recommend another source. I can not determine door manufacturer, 11 years old, but your 58-173 has identical cross section dimensions to vertical seals in our french door.PS after searching the web, I was impressed with your product line!
