Hey Scott, thanks for reaching out!
The length of safety chain will kind of depend on the length of your ball mount, but as a general rule of thumb you can use the 60" Curt Safety Chains with Latching Hooks # C19749 with the 10K Demco Cast Head Coupler w/ Jack Hole # DM37ZR.
These chains are rated for up to 5,000 lbs which works out for your trailer since at most it will weigh 3,000 lbs.
Let me know if you have any other questions!
