Trailer Lock for Specific 2 5/16-Inch Cast Steel Couplers with Safety Chain Storage, Model 2516-B2

This trailer lock secures specific 2 5/16-inch cast steel couplers and allows the trailer's safety chains to be secured inside the lock. Model 2516-B2 from Proven Industries is intended for the matching coupler style commonly found on equipment and dump trailers, making coupler shape an essential part of choosing the right lock.

Select a blue or black billet 6061 aluminum puck lock, or a solid 303 stainless steel puck lock, then choose keyed differently or keyed alike. Confirm that your coupler matches the 2516-B2 fit before ordering; the coupler size alone does not establish compatibility.

Frequently Asked Questions

Will Model 2516-B2 fit any 2 5/16-inch trailer coupler?

No. Model 2516-B2 fits specific cast steel coupler shapes, so a 2 5/16-inch size designation alone is not enough. Compare your coupler with the model's fit reference before ordering.

Can I secure my trailer's safety chains inside this lock?

Yes. Model 2516-B2 allows safety chains to be secured inside the lock when used with the matching coupler style.

What material is used for each puck lock selection?

The blue and black puck locks use billet 6061 aluminum. The stainless selection uses solid 303 stainless steel; these material descriptions apply to the selected puck lock.

What does the keyed alike selection mean?

The keyed alike selection specifies that all locks in the same shopping cart use the same key. Choose keyed differently when you want separately keyed locks.
