EC36-DUSTCAP is a part of the Caplugs line of dust caps, plugs, and caps. It is a high-density polyethylene (HDPE) dust cap that is designed to keep dust, dirt, and other particulate matter out of electrical enclosures, such as a control panel or other tight spaces. It fits into a 3/6-inch hole, and due to its tight-fitting design, it is able to prevent the ingress of dirt, moisture, and water vapor. This dust cap has a smooth outer surface, so it is easy to clean and resistant to corrosion. It also features a self-cleaning membrane which is designed to keep the inside of the cap clear of dust and dirt.
