No, it will not Glenn. The ICON Trailer Coupler Lock for Flat Lip 2-5/16" Ball Coupler item # AL63DQ requires a flat lip around and behind the receiver like our product pictures show. It looks like your trailer's coupler is similar to the item # CA-5400-B where the lip drops off right below the latch.
I recommend the BulletProof Hitches Extreme Duty Coupler Lock item # BPH96VR. This lock is built with a hardened solid steel bar to resist cutting and tampering, which also doubles as a visual deterrent. The lock mechanism is shielded by a rubber cap to prevent dirt and moisture buildup.
What kind of coupler do you have? I wasn't able to read the model information off of the picture you provided.

Jarred H I have a 2025 Mission MOCH8X16 16-foot aluminum trailer. Mission is an Alcom LLC brand. I believe the coupler to be a RAM CA-5400SH-Z 14,000 lb capacity 2-5/16? ball size durable zinc finish (include mounting holes for bolt on application).
