When doing construction it’s important to have proper dimensions for every segment of your project. Even minor mistakes in picking sizes can cause problems or result in a fully dysfunctional project. The same applies to rubber grommets, which is why picking out correctly sized ones is extremely important.

We aim to provide rubber grommet dimensions that accommodate your every need. These wiring accessories can be very important to the health of your home or provide the final element to some home DIY projects. For the sake of a faster shopping trip for you, we always have several options for rubber grommets when it comes to dimensions. There are four distinct styles of rubber grommets and they all vary in terms of inside diameter, outside diameter, groove diameter, groove width, and overall thickness. 

The inside diameter of a rubber grommet is a measurement of the distance between the two parallel points of the inner wall of the grommet. This is usually a dimension that’s most important when determining whether the wires you plan to plug through it will be snuggly accommodated or be accommodated at all. 

The outside diameter of these accessories determines the actual size between the outside edges of the item. You’ll usually measure it by simply putting a measuring stick across the hole you wish to utilize the grommet with and writing the result down. 

Groove diameter and groove depth determine the distance between grooves, small dents within the rubber grommet that aid its inside gripping strength, are important for determining the smoothness of your accessory. The utility of these dimensions is something you’ll have to decide for yourself, depending on your needs they may be completely unnecessary or very useful. Inform yourself before picking between them out for the sake of a better experience.

The last item of note is the thickness of these grommets, which impacts the ability of the grommet to provide isolation depending on its girth.

Whenever you are on the hunt for new grommets make sure to measure the objects you will use them on before making a purchase. These grommet dimensions are always key items to look out for during the purchase, even more so than the style of the grommet.
