replacement patio door handle set
Sure, this is plenty. I recommend our 82-030. The style is a little different but I'm otherwise confident that it will repair your door.
I'm shocked to hear it didn't work for you. The screw holes that mount the handle to the plate is 6-1/8", but looking at your first photo the holes that mount the base to the door look a lot closer together. What is the space between those holes?
If you did want to just return for a refund, you can see our return policy here.
I will need to return first one, also.
We don't carry a handle set with a 3-3/4" hole spacing. I've never seen a handle set with that spacing, unfortunately. I don't think any company makes that size. Please make sure that you're measuring from the center of each hole, not their edges. I think it's more than likely that your old handle has a 3-15/16" hole spacing, which is pretty standard for your door.
The 82-030 that you purchased originally has a hole spacing of 3-15/16" and should work on your door.
