I need a replacent door handle assembly in white. This is a Larson lock about 10 yrs old. Thanks

Hey Frank. This looks like the Larson 40-168, but please compare and let me know what you think. 

Great! All orders can be placed directly on our site at your convenience. I've linked to the product in question in my previous response.

Awesome! Thanks so much for the business, it means a lot! Please don't hesitate to reach out if we can be of any further assistance.

Hello again! This looks like a more typical storm door handle, though we unfortunately don't sell an identical replacement. I think the best option in our inventory is going to be the 40-049, but there are a couple things to keep in mind.

First, you should review the dimensions (shared below) to ensure that everything lines up. I'm chiefly concerned with installation hole spacing and the backset of the mortise (which is 7/8" on ours).

Another thing to keep in mind is the shape of the key lock. Yours appears to be round, whereas ours is more of an oval. I'm worried that the hole in your door isn't large enough to accept it. That's something you should check on, as well; we unfortunately don't sell anything with a round key lock like this.
