Review on 🔧 Super Lube Marine Dust Cap with Grommet by Tie Down Engineering – 81168 by Justin Bishop

Exactly what I needed at an affordable price. They come in pairs and are just a dust cap with a rubber cap that gives you access to your trailer's spindle oiler (it's not one of those caps that has an oiler attached). It's a tight and secure fit so I had to apply decent force with a hammer, but I also used a 2x4 piece of wood between the cap and the hammer to avoid damaging the cap and hit it from all sides. at the same time, so he went straight. They are definitely tighter than my previous baseball caps and I don't see them falling out on their own at all.
