Need a replacement handle and opening mechanism.

Sure! If only the handle is worn, you could consider our 39-226 hex spline replacement handle. If the operator is worn, you may need a new operator entirely. If you're in for a quick fix, you could consider wrapping the hex spline on the old handle with tape to pack it out. I've done this before in the past and it worked surprisingly well.

Gotcha. There are a couple different possibilities. I would start with the 39-329 and 39-330. Carefully compare our pictures and measurements to your own operator to confirm that they match. You would also need a new handle, since these operators use a different style spline. See the 39-205.
