lower right window crank and lower right hinge

This window operator appears to be a match for the 39-031 EntryGard Dual Arm Operator. To confirm that this operator is the correct replacement, carefully look over the dimensions below.

The opposite version of the operator can be found tagged below, along with the other compatible hardware and accessories.

Dimensions for 39-031

I suggest taking a look a the 36-048 and 36-004-10 (stainless steel) 2-Bar Hinge Sets. To determine which of these is the best option for your window, carefully review and compare the specifications on the website.

You will need to use one set to repair both the top and bottom hinges, for one side of the window. This will ensure they'll be a match. Both sets can be used in right and left handed applications.
