Frequently asked questions

What are isolation grommets used for?

They isolate the fastening points. Placed between the bolt and the equipment, they prevent vibration from bypassing the isolators through the hardware.

When should grommets be used?

Whenever isolated equipment has to be bolted to its base. Without isolation grommets, the rigid fastening cancels part of the effect of the pads or isolators.

Are they sold individually or in lots?

They are available in various quantities, depending on the project. Give the number of fastening points in your quote request.

What materials are available?

The grommets are made of elastomer. Dimensions are given in the PDF technical sheet.
