Abstract
A device and method for use is provided for grippingly engaging a tubular, in particular for gripping a wellbore casing. Drillable bridge plugs may use hardened buttons or other slip arrangements and materials that may be susceptible to damage when the bridge is being run into the wellbore. It may be desirable to protect the slip ring or the hardened buttons by shielding the buttons during run-in or by providing a standoff device so that the buttons may be prevented from contacting the casing until desired.
