These Greasable Bearing Protectors by Fulton offer you a hassle-free way to grease up your Boat Trailer Bearings before your next outing. The 2.441" fits industry standard 5,200lb - 6000lb 6 Lug Trailer Hubs. These Boat Trailer Greasable Dust Caps are Chrome Plated to make sure they stand up to the marine environment, and they will work well in Freshwater or Saltwater Environments. If you're typically going to saltwater though, you may want to consider the Stainless Steel Bearing Buddies (sold individually) we have on our site here.
The included Rubber Dust Covers are a great way to keep water from getting inside your trailer hubs, and will help to protect the Chrome surface of the Bearing Protectors.
