Quarter Dome Acrylic Mirrors

Quarter Dome Mirrors are a great choice for the intersection of two interior walls. Typically mounted at the intersection where the two walls and ceiling meet, the quarter dome mirror offers views of blind spots that often lead to accidents in the workplace. The images below show the most common way to mount quarter dome acrylic mirrors using the pre-drilled holes in the outer flange of the mirror.

Backing for Quarter Dome Mirrors

The quarter dome mirrors offered here are available with an acrylic lens with two different backing choices; hardboard backing, heavy-duty plastic, and no backing. Unless you have a specific need for backing, there’s really no reason to pay the extra money for backing for your quarter dome mirror.

• No Backing – only use for indoor locations.
• Hardboard Backing – Indoor use only.
• Heavy Duty Plastic – The heavy-duty plastic backing offered is high-density polyethylene, 1/8” product. HDPE is tough and rugged and virtually indestructible. When mounting an acrylic mirror outdoors, heavy-duty plastic backing (HDPE) is the recommended backing type. This is an excellent choice for garages, parking garages, etc.

Acrylic Quarter Dome Mirrors

Acrylic is the standard for indoor dome mirrors. Tough and bright, acrylic will withstand impacts (17 times stronger than glass), and if scratched, will polish out.

How Quater Dome Mirrors are Mounted

If you choose the quarter dome mirror with a hardboard back or plastic back, it is mounted using the d-rings on the backing. If the mirror has no backing, there are pre-drilled holes around the flange of the mirror for mounting. For additional information and instructions, please see this page: Dome Mirror Mounting.
