How do you measure for a cord grommet when you're ordering one?

Topic tags/keywords: question

This is a minor deal, but here it is: I needed a couple of cord grommets so I combined them in an Amazon order.

60mm grommets = 2 3/8”

They came from OTW in Fort Wayne, Indiana, and they are in sealed Rockler bags and labeled “grommet 2 3/8”” which is exactly what they are…if you measure the extreme diameter of the flange. They fit in a 2” hole.

I’ve always ordered and received grommets specced by the hole in which they fit. You need a 60mm hole for computer cables.

Did something change in the grommet universe while I was having a prolonged senior moment?

Kindly,

Lee

I’ve never ordered a grommet, Lee, but I sure like my Hartley-Swartley hole saw. :-)

You got the hole saw? Mine is just a half!

Wait a second! You must have bought the Aston-Flegler Semicircle Doubler Attachment with the high-temperature-resistant hermetically sealed sawdust ejection chute!

With a tool like that, I bet you can make perfect miters in a weekend!

Kinda enviously,

Lee

I thought Grommet was a British cartoon character. I don’t know anything about Hartley-Swartley hole saw, but I recently tried Renaissance Wax and its great!

I would be all sorts of annoyed by that. At least through Hillman grommets are measured by the hole size…

What sorts of computer cables are you running that are 60mm? that sounds like ancient parallel port stuff. Might be time to upgrade technology and put that old Dot Matrix printer to pasture…

dbhost, I dismantled a castoff printer years ago, big ol’ thang, and still use this lovely long magnet to hold my nail sets. Still serving!

But you ask an interesting question. What is the minimum size required these days to accommodate typical cabling? 60mm was a kneejerk determination on my part, and I may indeed be stuck in the Pleistocene.

Kindly,

Lee

Can be real uncomfortable being stuck in Plasticine.

I guess I come from the same alternate universe as you. I haven’t ordered grommets for many years, but when I
have, in the past, I always ordered from Hafele America. Their grommets are listed same size as install hole: ie: 40mm grommet fits a 40mm hole (1 9/16”) with an outside dia of 46mm and a 63mm grommet fits a 63mm hole (2 1/2”) with an outside dia of 76mm.
