Glue the corners down with a dab of silicone so that they can't slide.I’m looking for recommendations for tool chest liners. I prefer the mat type vs the “Fench Fit” type for things like combo wrenches, screw drivers, ratchet handles, breaker bars, etc. I’ve got decent socket storage but none of the mats I’ve tried have worked very well: Either the entire mat slid in the drawer or the tools slid on the mats. Suggestions??
