The Nite Ize Steelie Universal Adhesive Replacement Kit contains spare 3M VHB adhesive pads for the Steelie magnetic phone mounting system. Use it when you get a new phone or case, move a dash mount to another vehicle, or need to replace a worn pad. 3M VHB is a very strong foam tape that bonds securely to a car dashboard, a phone or a phone case. The kit holds six pads in total: two for the Steelie Dash Mount, two for the Steelie Magnetic Phone Socket and two for the Magnetic Phone Socket Plus, so you are covered for several phones, cases and cars. Clean and dry the surface before fitting a new pad for the best bond.
