Drenky Stainless Steel Deadbolt Security Door Lock with Keys Re-Key Lock Adjustable Backset (60mm - 70mm)

Good value for money and nicely put together. In particular the bolt part is long and strong so offers good security into the door frame. Having said that I can think of a few ways to get through this lock quickly so I'd use it as one layer of a security system rather than relying on it alone. Suitable for use on internal doors. Unlike some lock designs this doesn't require much width of frame to mount. The face plates engage with each other and the bolt mechanism via two long screws making for a solid unit when mounted. No instructions included but it's easy enough to work out. The key opening is offset so can be top or bottom of the housing and the thumbwheel on the back likewise has screw holes offset. The key opening offset should match the thumbwheel offset i.e both top or both bottom. If the lock is stiff or it's proving hard to get the screws through the bolt mechanism then check the offset front and rear match.

Screw not fit, No been picked up. Can I have my money back?
