This OtterBox 3600 IR Window Access Plug Kit replaces the standard end plugs on the OtterBox 3600 case with easy access plugs. The scratchproof IR window allows easy IR operation... right through the case! Not only that, but this kit allows access to SD and CF slots on top of PDAs, along with quicker access to the sync/charge connector. Made of durable elastomeric material for long life, this kit helps you to customize the OtterBox 3600 to your specific needs. Please note: These plugs are not completely watertight, but are highly water-resistant.
