Helo Brian, thanks for reaching out. If you are looking to get one of the Bulldog Collar Lock Couplers like part # BD028384, we do have a lock made specifically for this coupler, the EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D.

The coupler in the picture your provided is one of the jungle website off-brands that we don't carry. So unfortunately, I would not have a way to know exactly what lock would work with it. The fit may be the same as the Bulldog coupler but I typically recommend staying away from these knock-off brands. You get what you pay for and the customer support at that jungle website is non-existent. Here at etrailer there will always be a real person available to help you find the correct parts.
