Circular spirit level vials.

There are several ranges of circular spirit level vials available to suit different applications. Most of these vials will require mounting into a case or a bore hole as they are not necessarily level with reference to the bottom or top surfaces. Shown below are the different ranges we offer, please contact us to speak to a sales engineer who can give assistance with product design or selection.
