There are the sizes of the oval inner hole 6.5 X 14 mm X Cap dia. 43 mm X Length 35 mm for the dual coaxial cable line,the special hole dia.13 mm X Cap dia.33.5 mm X Length 33.5 mm and the special hole dia. 16.8 mm X Cap dia. 44 mm X Length 33.5 mm for the multi coaxial cables. A good design of 4 row pawl on the bushing foot 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.
They are made from high plastic materials conforming to RoHS standard with UV proof 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 is along the baseboard, wall, and other places.
They are available in black, in white ,in clear or other colour. Dual coaxial cable feed through bushing allow the dual cable line go through the hole in the bushing.
