Through passage forming members for wiring and piping materials

Abstract

This product relates to a through passage forming member for wiring and piping materials, which is used when wiring materials such as cables and piping materials such as electric wires and drain pipes are laid through wall materials, etc. Referring to a front view of the product in a sloped state, a reference exploded perspective view, and reference views 1 and 2 of the product in a used state, this product is composed of a flange portion and a sleeve portion swingably assembled to the flange portion, and a drainage pipe or the like can be laid inside this product by inserting the sleeve portion into the back of the wall through a through hole formed in the wall material. When the sleeve portion is swung obliquely relative to the flange portion to obtain a drainage slope, the cutting length of the sleeve portion can be determined by the slope cutting groove out of the slope cutting groove and horizontal cutting groove formed on the outer periphery of the sleeve portion, thereby allowing the protruding length of this product behind the wall in the sloped state to be accurately grasped and cut.
