Overview of the Three Types of 5th Wheel Hitch Jaw Mechanisms
Updated 04/16/2013 | Published 04/13/2013
Question:
Have you ever heard of a trailer coming loose from slide bar style hitch of any make with the slide bar in its locked position? I read that they are not as safe as a jaw style hitch. What advice can you give me? You sell them. I cant believe you would sell something not safe such as the 16516?

In speaking with Curt, they do not have any statistics regarding slide bar hitch failures. My technical contact at the factory stated that as long as the hitch is used in the manner intended, and the hitch and trailer king pin are properly maintained - that there should not be an issue.
I have compiled a short overview for you describing the three types of hitch jaw mechanisms available; ranking them good, better, best. I used the 16,000 pound base which is the rating of the unit you referenced.
Good: Slide Bar: This model is the nosiest out of the three types and you will definitely know that the trailer is back there, however, it is the least expensive of the options and is very safe. The Curt # 16516 you referenced is an example of a 5th wheel hitch with a slide bar jaw.
Better: Double Jaw: This model is quieter and gives you a more comfortable ride because it holds the king pin more tightly, however, you may still experience some movement with the king pin. This model is the middle of the road cost-wise and is also very safe. The Reese # RP30075 is an example of a double jaw fifth wheel hitch, see attached video.
Best: Single Jaw: This model is the quietest of hitches being that the king pin is completely captured and held by the hitch jaw, and would therefore give you the best ride quality. An example of the the Single Jaw is Husky Silver Series # HT31326-32042. I attached a video reviewing this hitch also.
