This is a "sliding" extension bar, which can be attached on top of the GRD18, to extend the

leverage capabilities of the GRD18, with larger centre-of-gravity (COG) array off-sets.

With the GRD18EXTBR mounted at the front side of the GRD18, the upward array tilt is

extended; With the GRD18EXTBR mounted at the rear side of the GRD18, the downward

array tilt is extended. The front and rear holes measure 14mm/0.55-in to facilitate 1,5T

shackles. Always use both quick release pins for the GRD18/ GRD18EXTBR connection.
