Abstract
Abstract 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
221 words
A device for firmly supporting a length of tube in predetermined spaced relationship from a surface, which comprises a hollow normally vertical cylindrical body the upper end of which is arcuately shaped to provide a bed for a tube, and the lower end of which is shaped to provide members adapted to support said device on a surface and channels adapted to permit cement to flow into and fill the interior of said body when flowed thereon; circumferential, uniformly spaced guide scoring on said support members adapted to guide cuts to shorten said members by a predetermined amount; a center apertured lug on each of said support members spaced from said lower end, said lug being adapted to permit said device to be nailed or bolted to a surface, and openable locking means adapted to secure a length of tubing in said bed, a plurality of fin pairs under said lug, each fin pair extending horizontally from each score in said guide scoring, the fins of said fin pairs being spaced horizontally apart by a distance about equal to the bore of said lug, the spaces thus formed being in vertical register with the bore of said lug; said fin pairs being adapted to provide support for said device when said support members are shortened by cuts through said guide scoring.
