Notice how the lock is activated by the kingpin hitting the safety trigger. The safety trigger eliminates the possibility of false trailer couplings to prevent dangerous high-hitching.

When the lock is "triggered" the jaw slides behind the kingpin followed by the wedge which takes out the slack. Patented No-Slack II jaw & wedge locking system eliminates slack automatically to save time, cut labor costs and reduce wear.

The pull force required to open the No-Slack II lock is less than any other standard fifth wheel on the market.

For added safety the positive secondary lock can be released by pulling the handle.

Increased surface contact with the trailer plate gives you more stability and durability.

No-Slack II is the lightest standard fifth wheel in the industry (218 lbs) to give you larger payloads for greater freight revenue

The No-Slack II is simple to maintain and can be rebuilt quickly without special tools.
