Gamber-Johnson's Mongoose Locking Slide Arm for cradles and docking stations was developed using extensive research from the public safety and Utility/TELCO industry and input from fleet managers and computer end-users. The Mongoose can be mounted on most upper pole assemblies and features an overall length of 9 inches from the center of the pole. The arm extends 4 inches forward for to a total length of 13 inches. "Slam and Lock" technology lets users push the computer back to the retracted position and automatically lock into place, preventing unwanted movement while the vehicle is in motion. Rotation of the locking slide arm can be 360 degrees locking in place at every 15 inches. The computer can be accessed easily from the driver and passenger seat. The Mongoose is made of heavy gauge, black powder-coated steel. The locking slide arm is securely bolted to the upper pole and is strong enough to hold a cradle or docking station while minimizing stress and vibration on the components.
