Clip and Wedge vs Spin Cap: Next Level vs Spin Doctor Tile Leveling System
Two ways to keep tile flat while the mortar cures. Here is how the Spin Doctor spin cap and the Next Level clip and wedge differ, with sources for every fact about Spin Doctor.
What is the difference between Spin Doctor and Next Level?
Spin Doctor levels tile with a threaded clip and a cap you spin down onto the tile surface[A]. Next Level uses a break-off clip and a reusable wedge pushed through the clip by hand or with pliers. Both stop lippage; they differ in how you apply pressure, which part you keep and how fast each one sets.
This page compares the two systems on the same criteria. For the method behind Next Level, see how the Next Level clip and wedge system works. For other clip-and-wedge brands, see Next Level vs Raimondi, Rubi and Perfect Level Master.

How does the Spin Doctor tile leveling system work?
Spin Doctor uses a threaded clip under the tiles and a cap you spin down onto the tile surface until the faces are flush[A]. The product listing says no tools are needed and that the system accommodates most tiles up to 3/4″ (20 mm)[A]. After the mortar cures, the cap comes off for reuse and the threaded clip is discarded[B].
How does the Next Level clip and wedge work?
Next Level uses a break-off clip under the tile edges and a wedge pushed through the slot of the clip. The wedge presses both tiles to the same plane; after the thin-set cures, the clip snaps off below the tile surface and the wedges are collected for the next job. More on the reusable tile leveling wedges.
Is a spin cap better than a wedge?
Neither is better for every job. A spin cap lets you dial pressure by turning; a clip and wedge is quicker to set. Bob Vila’s tile leveling roundup notes that winding the spinner takes a little longer than inserting wedges[B]. Pick by your volume of work, the tile you set and how you like to apply pressure.
What sizes does Spin Doctor come in?
Bob Vila lists Spin Doctor spacer thicknesses of 1/8″, 1/16″, 1/32″ and 3/16″[B], and the 1/32″ base is sold as its own product[A]. Next Level makes clips in 1/32″ (1 mm), 1/16″ (1.5 mm) and 1/8″ (3 mm). To match a clip to your tile, use the tile spacer and grout joint size chart.
Where can you buy the Spin Doctor tile leveling system?
Spin Doctor is sold through tile tool distributors; Detroit Diamond Tools, for example, lists the bases and the caps[A]. Next Level sells direct: request a quote with the clip size and quantity, and the order ships to you anywhere in the US.
