Can I weld this coupler instead of using bolts? Absolutely. While many users prefer bolting for easy replacement, the heavy-duty steel construction is suitable for welding to provide a more permanent and rigid connection to your trailer tongue.

Is the zinc plating sufficient for use on a boat trailer in salt water? Yes, the zinc finish is designed to provide excellent corrosion resistance. However, for maximum longevity in saltwater environments, we recommend rinsing the coupler with fresh water after each use. Is the zinc plating sufficient for use on a boat trailer in salt water?

Review: If your existing trailer ball hitch receiver is janky, replace it with this. - On our small 5x8 trailer the receiver ball hitch was rusted and we had to hit it with a hammer to get it to lock. We got tired of this and started doing research expecting to pay an arm and a leg to replace it. We were pleasantly surprised at the price, the ease of installation, the quality compared to the ancient one we were removing. This item locks like butter.. no hammer needed! The alignment was perfect and no additional holes had to be drilled. One suggestion would be is to make sure you have grade 8 bolts/nuts or higher. Also, thread lock (red color) is highly suggested so no bolts back out while towing. Review: Works great - Very new heavy duty coupler well worth the price ## Features - 3,500 LBS HEAVY-DUTY RATING Rated for a gross trailer weight (GTW) of 3,500 lbs, this 2" coupler is engineered for heavier loads.
