Hon&Guan 100mm Bull Nose External Vent 304 Stainless Steel 4 Inch Extractor Fan Vent Grille with Louvres Flyscreen and Gloves Round Air Vent Covers for Wall

6 inch vent cap in bright stainless steel even comes with gloves to protect it from finger marks.

Nicely made stylish external air vents with integrated rain cowl. No issues with sharp edges (as some reviewers have commented). My only negative is that the insect mesh seems quite widely spaced, tiny insects will most likely get through. However adding an accompanying internal air vent cover with mesh will fix this issue.

Well made, looks really nice and is easy to install

good product especially with the internal angled blades and insect mesh, time will tell with the quality of the stainless steel as we are in an marine environment...

The bull nose chrome vents are good looking/sturdy and do a great job of venting the sheds we use them on.

Compared to the plastic grilles we wanted a vent that would look good from the street. This does the job. Including gloves to save your fingers from sharp edges was a sign the manufacturer understands their product. Worked great for us.

The cowling, the fins and the screw holes are all orientated differently to each other - looks awful. Sent back

Looks good, but there are some sharp edges on it, make sure you wear the supplied gloves when installing the cover
