Lobo Tools Adjustable Drywall Inside Corner Trowel – 3" x 5"

When inside corners don’t stay at 90°, you need a trowel that can adapt on the fly. The Lobo Tools Adjustable Drywall Inside Corner Trowel is built for professional finishers who work a mix of standard corners, vaulted ceilings, and off-angle layouts—without stopping to swap tools.

This adjustable drywall inside corner trowel covers a wide range of inside angles, letting you fine-tune the blade to match the corner before you pull. From tight 90° corners to wide angles up to 150°, you get clean, even compound distribution with consistent pressure on both sides of the corner.

Built for Daily Jobsite Use

The 3" x 5" blade is formed from durable stainless steel that resists rust and wears evenly over time. The blade maintains proper flex for smooth compound control, helping reduce edge chatter and excess cleanup. A simple wing-nut adjustment system allows you to dial in the angle quickly and break the trowel down in seconds for fast cleaning at the end of the day.

Adjustable Performance Where Fixed Trowels Fall Short

Fixed-angle tools work until the layout changes. This adjustable drywall corner trowel eliminates the need to carry multiple corner tools by handling a wide range of inside angles with one setup. It’s especially useful on custom builds, remodels, and vaulted ceiling work where corners rarely stay uniform.
