Rubi tile Delta Leveling Kit with about 80 1/16 spacers, 100 reusable wedges, and a pair of pliers.
This kit was used once it install large format tiles in my house. I knew the kit contained way more than needed, but I wanted the best after learning that cheaper spacers often broke when clamping and wedging.
Everything is high quality; no spacers ever broke when clamping and wedging.
The kit was $55 new.
