Optional Grounding Cord (826SGC1000) Not Included. Diamond Stat is a dissipative/anti-static mat designed to absorb static electricity. The mat drains static electricity from the worker keeping sensitive circuitry from being damaged. The durable vinyl diamond-plate design provides non-directional traction, and is easy to clean. The top surface is combined with a dense closed cell foam base utilizing Notrax exclusive UniFusion technology virtually eliminating the possibility of de-lamination. Like all NoTrax laminate floor mats, Diamond Stat utilizes RedStop non-slip backing technology which keeps the mat from moving on smooth surface flooring
