Model 2517-D1

Awesome security solution for Demko Cast Coupler

Model 2517-D1 is an awesome product for slowing down or stopping theft, especially if parked near your residence! Quality construction and great service with fast communication after sale. I’m getting the AC-100 channel lock too!

Fit perfectly

The customer service at Proven Locks was great. I sent them a picture of my coupler and they told me the model I needed. If fits perfectly.

Worth the investment

Proven Locks are built like a tank. Heavy-duty, solid, and clearly made with security in mind. You can immediately feel the quality when you handle one. Definitely a worthwhile investment for protecting valuable equipment.
