Inertia Components - Ram ProMaster Van Roof Vent Adapter for 14x14 Opening

Stop wrestling with a curved roof and a flat vent. The Inertia Components - Ram ProMaster Van Roof Vent Adapter for 14x14 Opening is CNC-machined to match the exact OEM contour of ProMaster roofs, giving your fan a perfectly flat, stable mounting surface — no sheet metal distortion, no bent flanges, no improvising.

Features

• Fits 2014+ Ram ProMaster 136, 159, and 159 Extended models.
• Contoured-to-fit design – Engineered specifically for Ram ProMaster roof geometry. Whether you're mounting on a 136", 159", or 159" Extended wheelbase, our adapter eliminates shimming and guesswork.
  
• Prevents roof distortion – Distributes clamping load evenly across the adapter surface so your sheet metal and vent flange stay straight during and after installation.
