This listing is for a 12" wide trowel.

Pour thin-set mortar into the bay and pull the trowel along the work surface to quickly and evenly apply the mortar. Perfect for large flooring jobs! Hooks in the back can be used to attach a tool to pull the trowel. Photos show a paint roller used for this purpose, but it is NOT INCLUDED.

The depth of the trowel is adjustable from 1/4" to 3/8" to 1/2" for your specific needs. Adjustments are made by screwing the trowel face in a different position and holds firm once installed.
