Prototype Couplers Die Cast Lower Shelf E Couplers with compatible shank (1968-current) 6 Pack

Our die cast couplers utilize the exact same tooling Sergent Enginnering used for decades. This means that our die cast couplers are 100% identical to a Sergent die cast coupler. You will notice that the castings are very consistant and uniform with little clean up required by the end user for a perfect fit. These couplers also have the same short comings as a original Sergent coupler, notably the alignment pin goes through the shank and can be seen from the top of the coupler. Our investment cast couplers remedy this.
