Steelworx SWE1000 180° Fire Rated Door Viewer - Door Thickness 35-55mm - Satin Stainless Steel

Almost perfect

As one of the few satin chrome door viewers on the market I had little to choose from. However this was pretty much the most 'expensive' of the bunch out there. While The finish is great, Id say its nearer to just normal stainless than actual satin. Also a bit annoying is that the rivet holding the cover on the back hasn't been rivited on squarely. It onset line up with the slotted tightening keyway, so when you tighten the thing up on your door the poorly positioned rivet means the cover is on the pi** when in the closed position. Annoying.

Good kit

Bought it to replace existing, this one is much better.
