Cleaner Inside Corners.
Less Rework.
A shaped finishing trowel designed to follow 90° inside corners so both adjoining surfaces can be worked with a more centered, controlled motion.

Guide the Tool Through the Corner Instead of Fighting Both Sides Separately.
The working head is shaped for inside corners, helping keep the pass centered while smoothing material along both sides of the joint.
90° Guided Fit
The shaped head follows the inside corner during the finishing pass.
Both Sides Together
The supplier positions the tool for working both adjoining surfaces during the same pass.
Controlled Grip
A non-slip handle is intended to help maintain steadier pressure during repair work.
A Simple Process for Common Inside-Corner Work.
Apply suitable finishing material, align the shaped head inside the 90° joint, then move steadily along the corner using controlled pressure. Use only with materials and surfaces appropriate for the tool.

Drywall Corners, Wall-to-Ceiling Joints and Plaster Repairs.
The supplied product copy positions the tool for drywall finishing, plaster repair and other inside-corner renovation tasks.
