Asec Euro or Oval Cylinder Nightlatch Case (76mm) Review

This lock works as I needed it to - as a nightlatch for an outward opening door and an alternative to a rim cylinder.

The case is pretty good, and the latch operation works smoothly.

I won't know about the security until somebody tries to force it...

The plastic anti-thrust bit is apparently not as secure as a metal one, so an added anti thrust plate is recommended.

The strike casing isn't very impressive, as the coating is coming off and the metal is rusting, where the latch hits it.

But the above points are a result of it being a lower range unit, probably.

There are some other general issues with this type of lock that I was aware of before purchasing: it should be possible to blank off the outside face of the spindle hole, to avoid it being force that way. Also this product, along with most of the similar products out there, didn't have bolt through holes for the handle or the lock hole.

The question of it being easy to fit doesn't really apply I think: this depends on the fitter's own skills and tools. The size is pretty close to standard though, so if swapping out another lock there's only a bit of trimming and adjusting needed.
