Hit the brakes or take a tight corner and – whump! – whatever’s in your trunk or cargo bay goes flying, leaving spills and wreckage in its wake. Here’s the simple solution. The WeatherTech® CargoTech containment system consists of 4 strong plastic corners that corral most any load – from groceries and plants to tool boxes and coolers. And they work in virtually any trunk or SUV cargo area, thanks to the corners’ super-grippy underside that hangs on tight to carpet, rubber, vinyl or metal with no tie-downs needed.
