ROERSTOETTE.

摘要

A device for positioning and firmly supporting a length of tubing or pipe parallel to but spaced from a foundation, wall or other surface is provided by a hollow cylindrical body (preferably of plastic) the top end of which is arcuately shaped to provided a bed for said tube and the bottom end of which is shaped so as to provide members or legs and flow channels suitable for admission of cement into the inner part of the cylindrical body. The supporting members carry regularly spaced circumferential scoring or notches as guides to permit either or both members to be cut perpendicularly to the main axis of the cylindrical body by a predetermined amount, and they carry lugs (preferably of a length equal to the length of the scoring) to permit the device to be nailed or bolted to a surface. The top optionally carries a strap for securing the tubing to the bed.
