They are made from high-class PP, PE plastic materials to ensure the enough bearing capacity forces for the installation. It is widely used in the cable wire industry for installation, maintenance,services field when the cable line along baseboard, wall, and other places.
Being available in black, in white ,in clear or other colour. Single feed through bushing allow single cable wire go through the hole in the bushing. the dual feed through bushing can be gone through the dual cable wire when usage. The internal diameter of the hole in the bushings are designed according to the external diameter of the cable.
The internal hole dia. of 5.2 mm, 7.0 mm, 8.0 mm and 8.5 mm are available for the single cable line usage. The good design of four groups of inverted teeth on the plug rod body is to make the bushings not loose and slide in the drilled hole in the wall when it is installed and used, so as to strengthen the friction and firmness. These are often used for telephone cable wire, telecommunication and data system cables, and low voltage power cables. During the installation, to apply the silicone glue onto the back of the bushing near the wall and the drilled hole through the cable to prevent the moisture and dust from entering and penetration into the hole of the bushing and the drilled hole in the wall.
