Light-Duty Horizontal Extensions

Ergomart's light-duty horizontal extensions can increase the reach of some mounts, providing the attached equipment stays within the acceptable weight range. There are two size offerings, allowing you to add 3.5 or 7 inches of reach to the mounting solution. These can be combined to create additional lengths: 10.5" (3.5" + 7") and 14" (7" + 7") with one more point of articulation. The extensions are available in three colors - black, metallic gray (shown in the images below) and matte white.
