Progress Profiles Proleveling System Linear Bases — Level and Space in One Move, No Tool Required Most leveling systems make you carry two things and buy a third: spacers for the joint, clips for the lippage, and a tensioning tool to pull it all tight. The Proleveling System collapses that. Each linear base is notched to set the joint like a spacer and carries a threaded stem that a cap hand-tightens onto — pulling adjoining tiles perfectly flush with nothing but your hands. No pliers. No gun. No third product. Slide the base under two adjoining tiles, thread on a tensioning cap, and turn it down until the surfaces sit in plane. The system levels material from 2 mm (3/32") all the way up to 40 mm (1-5/8"), so it handles thin-profile porcelain and thick stone alike, and the bases come in four joint sizes — 1, 2, 3, and 5 mm — to match the grout line you're after. Once the thinset has set, kick or tap the cap in the direction of the joint and the stem releases at its engineered snap-off point, leaving the base buried and your surface flat. Setting delicate marble, polished porcelain, or natural stone? Add a Red Protection Cup under each cap so the rotating action never touches the finish. Why Tile Pros Choose It Spacer and leveler in one: The notched base sets the joint — no separate spacers No tensioning tool: Caps hand-tighten; leave the pliers in the truck Kills lippage: Pulls adjoining tiles into plane and holds them while the thinset cures Huge thickness range: 2 mm (3/32") to 40 mm (1-5/8") material Four joint sizes: 1, 2, 3, and 5 mm for the grout line you want Clean break: Engineered snap-off points release with a kick or a tap Floors and walls: Interior and exterior, large-format to thin-profile One less thing to lose on the jobsite: The tensioning tool you don't own can't go missing Pro tip: Match the base size to your grout joint and set the base before you place the second tile so it seats fully under both edges. Wait for a proper set before breaking the stems — and always kick or tap in the direction of the joint, never across it, so the break stays clean.
