FAQ+

What’s the difference between Z and telescoping brackets? Z-brackets are close-wall indoor mounts with pivot-ball aiming behind the mirror. Telescoping brackets adjust from 14.5″ to 21.5″ and are the right choice for outdoor, pole, and larger-mirror installs.

Does acrylic yellow in the sun? Our acrylic is UV-stabilized. Unlike low-grade imported mirrors, it will not haze or yellow over normal outdoor life.

Can I get a custom SKU? Yes — if your size, backing, or bracket is not listed, contact us for a custom quote.

What is a convex mirror and how does it work?

A convex mirror is a curved mirror that bulges outward, away from the observer. Unlike a flat mirror, which reflects light in a straight line, a convex mirror reflects light outwards. This causes the image formed by a convex mirror to be virtual, smaller, and upright compared to the actual object.

The way a convex mirror works is through a phenomenon called "divergence." When light rays hit the surface of a convex mirror, they spread out or diverge. This divergence creates the illusion of an image being formed behind the mirror. The further you are from the convex mirror, the larger convex mirror is a curved mirror that bulges outward. It works by reflecting light outwards, causing the image to appear smaller and wider than it is. This type of mirror is commonly used for surveillance purposes as it provides a wide field of view.

An indoor convex mirror with an acrylic lens and hardboard backing is a valuable tool for enhancing security and safety in various indoor settings. Available in different sizes, these round convex mirrors are designed to offer a wider field of view when your visibility is limited or obstructed.

The acrylic reflective surface of the mirror ensures clear and distortion-free images, making it an effective solution for covering blind spots, and intersections, or enhancing store security in shops and retail stores. The hardboard backing adds durability and protection to the acrylic lens, ensuring its longevity even in high-traffic areas.

So how exactly does a convex mirror work indoor convex mirror has a hardboard backing not suitable for outdoor use. Click here to see our outdoor convex mirrors, for parking lots, parking garages, and as traffic mirrors for traffic safety the outdoor convex mirror is recommended. The high-density polyethylene backing makes these mirrors heavy-duty outdoor mirrors.

Acrylic Convex Mirror: Perfect Tools for Workplace Safety and Theft Deterrence

The indoor convex mirror with acrylic lens and hardboard backing is the go-to workhorse for indoor security mirrors. The acrylic lens is lighter in weight (when compared to glass) and offers a brighter reflection than glass and polycarbonate. Although it can scratch, there are polishes you can use to buff it out. This polycarbonate convex mirror stands to impacts, practically does not break, has excellent reflection properties and does not scratch easily. A special aluminum profile applied around the mirror offers increased strength and durability. Can be used both indoors and outdoors.

The hardboard backing is excellent for indoor use (not recommended for outdoor use). There are two mounting brackets; a z-bracket and a telescoping bracket. The primary benefit of the hardboard backing in a convex acrylic mirror is to provide the mounting brackets and to protect the mirror lens itself. However, the pressed hardboard backing does not do well in humid, wet weather. If you plan to mount the mirror in a location where humidity, moisture, or extreme temperatures are an issue, we recommend the outdoor convex mirror with heavy-duty plastic backing.

The Larger the Mirror, the More Visibility: Inches Equal Feet of View

When considering purchasing a mirror, it is important to note that they come in various sizes, ranging from 12 inches to 48 inches. As a general rule, for every inch in mirror size, you can expect approximately one foot of viewing distance. This is a conservative number and factors such as overall distance, how fast objects are moving, and if the oncoming intersections provide a straight or curved field of view.

Find the Right Mounting Bracket for Your Indoor Convex Mirror

To ensure the proper installation and stability of your indoor convex mirror, it is crucial to choose the right mounting bracket. We have two mounting options to choose from: the z-bracket and the telescoping bracket.

The z-bracket is a simple yet effective choice for mounting your convex mirror. It consists of two metal brackets shaped like the letter "Z". These brackets can be easily attached to a wall or any other flat surface using screws or adhesive. The mirror is then secured onto the brackets, on a small pivot ball, providing a sturdy and reliable mounting solution.

What are the advantages of using a convex mirror over a flat mirror?

Convex mirrors offer a wider field of view and eliminate blind spots, making them ideal for surveillance in areas with high traffic or security concerns. They also provide a greater depth perception and can reflect light over a larger area, enhancing visibility in dimly lit environments.

On the other hand, if you require more flexibility in adjusting the angle and position of your help with bracket options, smaller mirrors are available with a z-style mounting bracket. In comparison, oversized mirrors are only available in single or double-mounting telescoping bracket arms. Please view this guide for additional information. Mounted on a fully adjustable fixing bracket for wall offering optimum positioning in every installation.

How do acrylic and polycarbonate compare for impact and scratching?

Impact resistance describes resistance to a strike or shattering; it does not describe surface hardness or scratch resistance. NSM uses approximate material comparisons of 15× glass for acrylic and 250× for polycarbonate. Published figures vary by grade, thickness and test: Advanced Plastiform, for example, cites about 10× for acrylic and 250× for polycarbonate. Acrylic is generally more scratch resistant than uncoated polycarbonate, while glass is harder at the surface. These material comparisons are not a model-specific test rating or a bullet-resistance certification.

How should I clean and care for an acrylic mirror?

Use spray wax or plastic polish on the front surface and wipe with a clean, soft cloth. Do not use glass cleaners. Washing with a soft cloth works, but repeated washing can gradually create fine scratches. Read the Acrylic Mirror Care guide for cleaning, drilling, and fastener precautions.
