This signal head can be used with any of our Signal Ground Mast Assemblys to create your own unique signal build. The kit consists of pewter, resin and brass parts. See instructions tab for more information. UPDATE: We have updated this signal head by including a small screw (Button head TorX Screw - 000-120 Thread 3/32" Long) that will secure the head to the bracket. This will make this connection more secure. You will need a IP1 Torx Plus Driver. We sell these drivers on our website under the Paint/Tools drop down menu.
