To determine the proper grip rivet to use, measure the material thickness with a 269C3 grip gauge as shown below. Insert the grip gauge into the prepared hole, draw gauge back until lip contacts back side of structure and read where front side of structure coincides with number and lines on gauge. Always read the next height number (if reading is directly on a line you may use either that grip or the next higher one).
