A rigid tube support having no flexing sections comprised of an elongated rectangular shape having arcuated round ended slots for restraining multiple PEX (crosslinked polyethylene) tubes used in construction for hydronics and plumbing. These slots have openings to allow the tubes to be freely inserted radially into the openings. These slots further have within each of them a single semicylindrical protrusion axially oriented with the tube trapping the tube from sliding out radially once inserted. The protrusion forces the tube to be temporarily deformed during insertion. When in final position the slots are large enough to allow the tubes to freely rotate and slide axially within the support accommodating linear thermal expansion of the tubes. These larger slots also allow for tube rotation for ease of installation. The curved opening enables the support to be used horizontally as well as vertically. The support keeps the multiple tubes spaced apart and offset from the mounting surface to allow for insulation to be later applied to the tubes. Placed perpendicular and in between each of the tube openings are apertures through which fasteners are inserted. Although there are multiple apertures only two fasteners are required.
