The RLO-22x fits the yellow top Westeel (both the 14' diameter and the 19' diameter) and the orange top Butler. All of the hardware is on the outside of the lid to provide more room for the auger.
The lid slides down a rail instead of hinges and operates with a long lasting steel cable, with a short chain to lock the lid open. It lays down to prevent auger contact. These Remote Lid Openers can usually be installed in under an hour.
All of our openers work with your existing lid, making them a cost effective option if your current lid still fits well. Westeel replacement lids (22") are available here, and Butler replacement lids (24") are here.
