All Rocklock Couplers were designed with one very important feature in mind. All Rockland Rocklock couplers and attachments for machines of the same general weight and horsepower are interchangeable. With a Rocklock system, when you trade your loader you don’t have to trade attachments! Many people have purchased coupler systems expecting interchangeability only to be severely (and expensively) disappointed. Don’t let this happen to you. Specify the Rocklock Coupler System—the coupler designed with the customer in mind.


  • The best connection for loader versatility!
  • Built to interchange with major coupler systems! We can design your new coupler and attachments to work with existing equipment!
  • Attach forks, rakes, blades, booms, and buckets to your loader with the flick of a switch.
  • Available as hydraulic.
  • Mounts with standard factory pins.
  • Comes complete with all hoses, valves, and fittings required for operation.


Rockland Rocklock® Couplers are guaranteed against failure due to defective design, materials, or workmanship for a period of two years or 4,000 hours.
