What sets it apart from the rest
This tool combines practical on-board features with a thoughtful material choice. The lightweight composite body keeps you in control without sacrificing strength, while the integrated puncture tool and spout cutter streamline your workflow.

The ladder hanger is a small but meaningful enhancement for overhead projects, helping you stay organized and productive from start to finish.
Tips for best results
- Prime the gun with a steady trigger pull to maintain a consistent bead width, especially on thicker sealants.
- Use the built-in spout cutter to trim the nozzle at the desired angle for clean, directional flow.
- Keep the cartridge upright during application to prevent air pockets that can affect bead consistency.
- When working overhead, position the gun on the ladder hanger for quick access and steady control.
