Progress Profiles - Proleveling System Rotating Knob Cap (50 Pack)

The Proleveling system is a revolutionary and innovative leveling system for laying medium and large materials with a thickness between 3 and 40 mm. The patented system consists of two components: - A leveling base (1-2-3-5 mm format) with spaced notches that allow you to space/separate/join floors of any type and material in a linear, crisscross, or semi-crisscross manner, with joints of 1 mm, 2 mm, 3 mm, and 5 mm. - The threaded rod is fixed perpendicular to the base, allowing for easy adjustment by rotating the cap during installation. Removal of the cap and rod after the materials have set is facilitated by strategically placed break points that are released by kicking or tapping the cap in the direction of the joint. A single plug fits all threaded rods and can be reused countless times, resulting in significant cost savings. The new PPLS system (patented) helps reduce or eliminate lippage when installing various types of mortared floor or wall materials, including: Large format tiles, natural stone, low profile tiles, and many others.
