See how our outside corner baseboard molding adds a durable, professional finish. This video shows installation tips for commercial and residential spaces.

How do you cut this molding for an outside corner?
For a standard 90-degree corner, set your miter saw to a 45-degree angle. Place the molding on the saw (typically bottom face against the fence) and make your cut. Cut the adjoining piece at the opposite 45-degree angle. Always use a blade designed for non-ferrous metals.
How does the adhesive triangle tab work?
The integrated triangle tab sits behind the molding, providing a large, flat surface area for the construction adhesive (sold separately) to bond to the wall. This creates a very strong bond without any visible screws, resulting in a clean, seamless look.
Why do you use 3003 aluminum for this molding?
We use 3003 aluminum alloy because it offers the perfect combination of moderate strength, excellent formability (for the 90-degree bend), and high corrosion resistance. This makes it ideal for a long-lasting, durable finish in high-traffic or damp areas.
Can I install this over my existing baseboards?
This product is designed to be the baseboard corner itself, fitting from the floor up to its 4" or 6" height. It is not typically designed to fit *over* existing wood or MDF baseboards, but rather to meet up with them or be used as the complete baseboard system.
Do you offer bulk pricing for contractors?
Yes, we offer bulk pricing and commercial-grade solutions for contractors, installers, and B2B clients. Please contact our sales team at info@tread-ware.com for a quote on your project.
