The LEVEL5 Outside Corner Applicator is a specialized tool for evenly applying compound onto 90 degree outside corners.

Connect to any of your favorite LEVEL5 application tools, such as the MINISHOT™ Gas-Assisted Applicator Tube (#4-772), the Compound Tube (#4-741), or Corner Applicators (4-701 & 4-702), and you will make quick work applying bedding mud to outside corners prior to applying bead.

Manufactured from extruded glass-filled polymer, the LEVEL5 Outside Corner Applicator has channels for efficiency applying even ribbons of joint compound through the attachment onto both sides of the corner simultaneously. The LEVEL5 Outside Corner Applicator is longer than other competing applicator heads, which effectively eliminates ‘head flip’ when varying degrees of pressure are applied to the attachment while on the wall.

For handle attachment, the LEVEL5 Outside Corner Applicator features an integrated universal ball socket manufactured from premium stainless steel. This socket is compatible with ball end adapters from most leading manufacturers.


  • Extruded from durable glass-filled polymer

A Pressure Washer Makes Cleaning Fast

To ensure that your LEVEL5 automatic and semi-automatic tools last longer, it is crucial to clean them thoroughly before storing them between jobs. Although not required, a lightweight and portable pressure washer, commonly used for washing vehicles, can make light work of the cleaning process. There are many cost-effective options available on Amazon with good ratings.

Lubricate After Cleaning

Once your automatic and semi-automatic tools are clean, it is important to lubricate all the moving parts to displace any remaining water and reduce the risk of corrosion. IMPORTANT: avoid using standard WD-40 or similar lubricants as they can be caustic and damage the rubber seals and gaskets, which in turn can affect tool performance. In fact, it's best to steer clear of any spray lubricants unless you are certain of the propellant used. For example, many spray cans use solvents like benzene as a propellant, which is a solvent.

We recommend using simple, low cost 3-in-1 machine oil, available in metal squeeze cans, to lubricate every moving part before and after use. Alternatively, if you prefer to spray the oil onto your tools, you can buy it in a larger format and apply using a hand spray bottle.

  • Outside Corner Applicator

    Nate Albro, May 8, 2023


    Had issues with fitment of original part shipped...talked with Robbie over the phone and we couldn't get it figured out. He had a replacement shipped out same day (within a couple of hours), no questions asked. No issues with the new part, performs (and fits) exactly as it should. Outstanding communication & customer support throughout, thanks! ????
