Hello there, based on that code and the style of the arm, I think you have an operator like our 39-171 or 39-172, but without a clearer picture of the entire mechanism I can't be entirely sure. View the picture below to confirm, let me know if anything differs. If the rivet or other specific parts of the arm or mechanism body break down, I am afraid the entire operator must be replaced. Let me know if you have further questions. 
Dimensions for 39-171

That's perfect, thanks. This does indeed look like the 39-171; so long as the dimensions I posted previously match, I think this can work for you. Just let me know if anything differs. For a new handle to go with this operator, see our 39-114L. If your old stud bracket that the operator arm attaches to is undamaged, you can just reuse it; otherwise, see our 39-516. |
