Get more clearance from your 1A Raingutter Towers for any domed roof, sun roof, or pop-up camper roof.
Yakima 1A HiRise Spacers convert your 1A Raingutter Towers into 1A HiRise Towers, creating an additional 3.5 inches of roof clearance. These spacers are perfect for domed roofs like those found on VW buses and converted vans with rain gutters where you need extra clearance for your roof rack.
3 1/2" spacer converts standard 1A Towers to 1A HiRise Towers for more clearance
I also used these on my vanagon to get some space under the crossbars. They work perfectly. Only gripe is that you need boltcutters / hacksaw to get them installed on the normal mounts. Little bit of a PITA.
