This is an exterior door handle from the sliding glass door to an RV. It is plastic with 2 threaded metal inserts. The 5/8" diameter hole is for a lock cylinder. the inserts are spaced 3-15/16"

Hello!
This reminds me of our 82-306 keyed exterior pull but it's not available in white, unfortunately. The next best thing we can offer is our 82-030 handle set where the outside pull can be adapted to use our 82-310 key lock (sold separately). Look these parts over and see what you think.
