FAQ

What is the difference between full dome, half dome, and quarter dome mirrors?

Full domes provide near 360-degree overhead visibility and are used above open areas or four-way intersections. Half domes are useful at T-intersections or wall-adjacent areas. Quarter domes fit corners and L-shaped corridor intersections.

How are half dome and quarter dome mirrors mounted?

Half dome and quarter dome mirrors usually mount to walls, ceilings, or corners through pre-drilled rim holes or d-loop rings on backed versions. Install them into solid material or appropriate anchors at a height that gives pedestrians and equipment operators a clear view.

When should I use a full dome mirror instead of a convex mirror?

Use a full dome when people, carts, forklifts, or customers approach from multiple directions and overhead panoramic visibility is needed. Use a wall-mounted convex mirror when the primary need is one or two approach directions around a corner or obstruction.

Why does my quarter dome mirror look smaller than the size I ordered?

A quarter dome uses the radius of the original full dome as its straight-edge measurement. For example, a 32 inch quarter dome will have straight edges of about 16 inches because it is one quarter of a 32 inch full dome.
