Construction:
The clamshell consists of a two part mounting assembly. The
hinge pins on the pole mounted half are stainless steel and
fit into the ears on the signal mounted half.
The pole half of the assembly is designed to fit the
curvature of poles 4"; in diameter and larger.
Mounting:
The clamshell is mechanically designed to allow for various
types of mounting such as banding, thru-bolt or lag screw
mounting. The bolt holes are elongated horizontally to allow
for rotation on the pole.
The closed signal half of the assembly is secured to the pole
half through use of a flathead socket bolt and tightened
using a 3/16"Allen wrench.
