What is a Corner Guard?

Whether you’re managing a large-scale construction project or simply protecting your home from everyday wear and tear, corner guards are a must-have for maintaining clean, damage-free walls. A corner guard is a surface protector molded to a 90-degree angle, designed to shield corners from scrapes, dents, and other damage.

From drywall corner protectors to countertop corner protectors, these versatile tools come in a variety of materials and sizes to suit any environment – residential, commercial, or industrial.

FOUR CORNER GUARDS FROM TRIMACO

Trimaco offers a wide range of wall and corner protection solutions to meet the demands of any job site or space. Our lineup includes:

1. NEW Stainless Steel Corner Guards

Trimaco’s Stainless Steel Corner Guards are built for high-traffic environments like hospitals, warehouses, and commercial kitchens. These construction corner protectors are crafted from high-quality stainless steel and feature a precise 90-degree angle for a snug, secure fit.

• Easy Installation: Pre-applied release tape makes installation quick—just peel and press.
• Durable Protection: Prevents dents, scrapes, and damage in busy areas.
• Sizes: Available in three widths and two height options.

2. NEW Peel-and-Stick PVC Corner Guards

Looking for a fast, no-fuss solution? Trimaco’s PVC Corner Guards are perfect for quick installs and long-lasting protection.

• Peel-and-Stick Application: Clean the surface, peel the liner, and press firmly from bottom to top.
• Versatile Sizing: Available in multiple widths and in both 4-foot and 8-foot heights.
• Ideal for Residential and Light Commercial Use: These counter corner protectors are a great choice for protecting drywall, painted surfaces, and more.

3. Clear Plastic Corner Guards

• Self Stick Corner Guards: Trimaco’s Self Stick Corner Guards are designed with clear, hard plastic. The material has been molded to a 90-degree angle for easy installation. Self Stick corner guards feature a release paper which can easily be removed, relieving the sticky adhesive. Available in 4-foot and 8-foot options.
• Nail on Corner Guards: Looking for something a bit more permanent? Although designed with the same hard plastic material, Trimaco’s Nail on Corner Guards come with specially designed screw/nails, which can be easily drilled into the plastic protector. Nail-on corner guards are ideal for commercial projects. Also available in 4-foot and 8-foot options.

4. Flexible corner guards

The newest addition to the wall corner guard family. Trimaco’s New Flexible corner Guards are durable, long lasting and provide the ultimate impact protection. The versatile material can be used not only on corners, but round surfaces and furniture as well. Rubber corner guards are clear in color and measure 8-feet in height.

How to Install Corner Guards

1. Clean your surface: First and foremost, if you are applying a corner guard that features an adhesive backing, clean your surface. The adhesive will not stick properly if dust or dirt is present.
2. How high should you install your corner guard? Depending on your job type will ultimately determine how high or low you want to install your corner guard. If you plan on moving low standing furniture or equipment, lower is better to reduce the risk of damages. If high traffic is a risk, ensuring the corner guard is installed at shoulder height should be considered.
3. Install:
   • Self-Stick Corner Guards: Trimaco’s Self-Stick Corner Guards and Flexible Corner Guards are quick and easy to install. After cleaning your surface, remove the release paper from the plastic. Slowly adhere the wall corner guard to your desired height and press firmly into place.
   • Nail-on Corner Guards: Nail-On Corner Guards should be installed with a hammer. To install, hold the corner guard in place, and nail in the screw/nails to secure. We recommend spacing out the nails roughly one foot from each other, alternating between the sides of the corner guard.

How to cut plastic corner guards

Although Trimaco offers the hard plastic corner guards in 4-foot and 8-foot options, sometimes a more specific height may be needed. To cut the hard plastic, we recommend using a sharp knife or saw. Flexible, plastic corner guards can simply be cut with a pair of scissors.
