The RTC Spin Doctor Tile Leveling System uses three main pieces to assist tile installers in achieving a flat, lippage free tile installation:
Spin Doctor Free Spin Caps which is made of high quality durable plastic that ensures it can be re-used for multiple jobs. The window openings on the cap allow the user to see the grout joints for accuracy when installing, a trait that is lacking in many other leveling systems.
Color Coded Spin Doctor Threaded Spacer Post Bases which allow users to combine the utility of tile leveling along with the utility of tile spacing. The white spacer posts come in 1/16″ (1.5 mm) spacing, the black come in 1/8″ (3 mm) spacing, and the grey are 3/16″ spacing (5mm)
Spin Doctor Clear View Shields (optional) that take all friction off the surface of the tile, keeping joints in place while tensioning the cap and distributing vertical pressure more evenly. The clear view shield is highly recommended for natural stone to protect the delicate surface.
