The red wall plugs are mainly used in the light and medium duty building substrate and designed with two way expanding function having high pull loading strength and designed protruding side fins on the plug to prevent rotation and falling out from the drilled hole and the protruding head lip design can firmly hold the drilled hole to avoid sliding to ensure the anchorage and fixing strength.That realizes a fast and safe installation purpose in the concrete,masonry, or brick place for the user.
They are made from the high class PE plastic materials in red conforming to RoHS certificate. It is not shrink or rot and bears high and low temperatures and damp environments. Because of self lubricating feature, to avoid bonding the screw and the plug together.
The size of red wall plug is φ 5.5 mm X 32 mm Length, To drill a exact hole according to the diameter of the plug and the substrate materials and to insert the plug into the hole and to fasten the self-drilling screw or wood screw with the screwdriver during installation. In most cases, Red wall plugs are the main wall plug used by electricians in the cable wire installation field. There are many kinds of wall plug, but the most general working principle is to use a plastic conical plastic plug to insert the pre-drilled hole and tightened the screw into the center of wall plug and let the plug expand conforming tightly to the wall substrate material.
