Unfortunately with some older versions of this operator, the covers were not meant to be removed. Note too that when the cover breaks on these, it might be a sign that the operator is wearing down anyway and ought to be replaced. This is our 39-220B. It can work with cover and handle kits like our 39-376 or 39-452. Let me know if you have any further questions. |
