The cap is the part of the leveling system you touch on every single tile, so it has to be fast and consistent. Spin Doctor Caps use a patented free-spin design that tightens down by hand in seconds — no pliers, no tools, no fighting lippage. Each cap delivers controlled, even tension that pulls adjacent tiles into plane, and because they're reusable you recover them after the pour and run them again on the next job.
You get 100 reusable caps per box. Pair them with Spin Doctor threaded bases (available in 1/32", 1/16", 1/8", and 3/16" joints), add anti-friction shields for polished tile, or grab the complete Pro Kit to start from scratch.
Pro tip: Spin down until the tiles just pull level — the free-spin design gives you feel, so let it stop you rather than cranking. Rinse the caps at the end of the day so cured mortar doesn't gum up the threads before their next use.
