Legance Handle Set Replacement?

A contractor from Maryland says:
The lock part of the handle will not stay open making it difficult to close the door. I can not find anything that looks close to this style handle. The original installer noted the brand of the door as legance brand. Installed in 1992.

Thanks for posting. Measure the hole spacing, or the distance between the center of each mounting hole on the handle set. If the hole spacing is 4-15/16", see our 82-009A. This has a similar clamping mechanism to your old handle set. Take a look and see what you think.
