Usually a sliding door, be it wooden or aluminium (steel sliding is rare), will need 4 items to work:
- A hook lock mortise
- A Key Cylinder
- An escutcheon (or common people call, key cylinder cover)
- A door pull
But there are some other alternatives like the above photo. The all-in-one sliding hook lockset.
There are many China brand, they break easily.
But there are also good one, although not easy to find. Still using Zinc Alloy material, but is thick and heavy, and good mortise mechanism.
If you have budget, however, should just stick with the 4-piece hook lock. Priced higher, but so long lasting and so reliable. Stronger, piece of mind, and made of stainless steel material.
