Built with 40% thicker walls, smooth seam welds and a double-reinforced floor pan for long term durability, make these the tool boxes industrial professionals prefer. Seal-Tite Tool Boxes feature twin heavy-duty gas struts that lift the lid automatically for easy, one-handed use. Seal-Tite boxes are also equipped with a weather-sealed dome lid and triple O-ringed push-button sealed locks, for weatherproof security. Heavy duty mounting clamps offer easy, no drill installation on most models.
