Signal standard with mounted APC heads for our signal bridges.  All of our basic bridges come with two stud mounts per track, one for each direction.  These heads mount on those studs, you just slip the pole over the mounting stud and apply adhesive to fix the head in place.  The bridges also have conduit mounted across the top of the bridge and on one side, you route the signal head wiring through these conduits.

Signal head materials are brass and steel and the head electronics include our super bright LEDs and Aspect Priority Control (APC) built in electronics.  All heads are weather sealed and suitable for continuous outdoor operation in any weather.  Multiple head configurations have a ladder mounted on the back.  The signal standard is made of brass tube and has a ferrel (witch hat) on top.
