Inconvenient feeler gauges, clay, calipers and thumbscrews are no longer necessary to check gaps between the door and door opening flange or deck lid and deck lid opening flange.

To inspect a vehicle, simply place the Hub inside the car, attach the 237W or 238W Seal Gap Gauge(s) to the flange. Then apply the door magnets to “flush” the door or deck lid and sample the readings. Data is stored in a convenient file format for use in your SPC program.
