Atrium Vinyl Sliding Door Mortise Lock

Hi,

I need a replacement mortise lock for an Atrium Vinyl Sliding Door.

The part number is PM520A.

I have attached some photos of the part with some approximate measurements.

Would Part 82-239 be a suitable replacement?

Would you be able to source or sell the exact same replacement part?

I live in Canberra Australia. Can you post this part to me?

The door was manufactured in the USA but I can't get any replacement hardware in Australia.

Thanks for your help and advice.

Regards

Brandon
