I moved into another home & the patio door lock is broken. What is broken is the small spring that operates the hook latch to secure the door.
The sticker on the door has the following information: MFG Code PHP-28 Series 870 SGD and below that is SGD-R20 96x96
I cannot find out any information on where to purchase a replacement locking mechanism.
I would appreciate any information you may supply.
thank you
John
