150x57mm Oval Metal Cable Grommet

Dear Sirs I would like clarification on a couple of points relating to the 150-57mm oval metal cable grommet you supply please: 1. how large is the aperture for passing a moulded socket through with the grommet cover in the open position? 2. is the brushed stainless steel lid set in a dark grey body as in the photo on the website? 3. is there a lip on the body of the unit as shown on the tech drawing that would cover the edge of a hole cut in the desktop? (I assume it is but this isn't clear in the photograph) Many thanks and please call if any of the questions need explanation. Guy 07918192953

We've just uploaded a new technical drawing we've obtained from the factory, so if you click the Technical Data tab (next to the Description tab), then you should see everything we have available. I've physically checked one of these parts and there is a lip on it to cover the edges of the hole - around 3mm approx. all the way around! I've also added a new image which hopefully shows the finish better, but I can confirm the plastic surround is definitely Black on the sample I've just pulled out on my desk! At the end of the day though, it's a standard stock part - so no problem if you wanted to return it, if it doesn't prove suitable for your application!
