With the reliable 3/4" Twist Lock Plunger from B/A Products Co., you get a much easier and more reliable option to use than the old style locking pins. The design of this plunger effectively allows for one hand operation to open the assembly and then easily put it into the automatic locking position for a reliable hold. The pin has been designed to engage fully once the holes in your bar line up. Offering a durable hold, this twist lock plunger can be used on sling arms, stabilizer legs, wheel lift forks, and more.
