Saddle bands mount copper tube directly to a surface; and pipe rings, in conjunction with single or two-piece spacing clips, can be used where tubing needs to be mounted away from a surface. Brackets, two-part pipe joint clips and stems provide the installer with additional options for a variety of other installations.
