Fit and Compatibility of Pro Series A-Frame Coupler with Trigger Latch

Question:

Is a 3D solid model available for this component? Designing/modeling a new camper and the PSE338050303 has been identified as a candidate for the hitch. Thanks

The Pro Series A-Frame Trailer Coupler with Trigger Latch - 2" Ball - 5,000 lbs # PSE338050303 does not have a 3D model available. What I can give you is some of the fit descriptions to assist. The coupler will use the trigger style latch that fits a 2 inch diameter hitch ball. The hole for the jack is a standard 2-1/4 inch hole with 3 holes that use 3/8 inch bolts with 16 threads per inch to secure the jack.

The coupler is 14 inches front to back and has a standard angle of 50 degrees on the inside edge. I've attached a photo to assist.

I have a utility trailer with a 2 trigger latch coupler. there is no way to lock it when attached to a ball hitch.... is it possible to get a kit to place the moving parts.

If you need a lock for your trigger latch coupler, the Bulldog # BD580403 should work really well. It's designed to slide through the hole on the trigger assembly and lets you actually lock the coupler onto the ball when attached.
