Top 4 Questions:
When do you need an arm support?  
Boom Tip Support or Bolt Down Cradle is needed for arms over 18 ft long.
What length arm should I order for a 18 ft plus barrier gate that requires a fixed cradle?
When figuring your arm length, measure the “dirt to dirt ” distance from edge of asphalt of the roadway or back of curb(s) and add 1.5 ft or 18 inches to that dimension for the total arm length to order, but if using a tip support arm length isn’t critical.
How is the arm distance measured?
The arm length measurement starts even with the arm side of the base plate edge that runs parallel to and is closest to the street.
Can the barrier gate arm be locked?
The arm can be locked in up or down position with a simple medium size padlock.

General Information

Manual Barrier Gate Base:                                                                  
The MB832 is available in sizes from 8 to 32 ft. The arm is completely self-supporting up to 18 ft and a cradle or tip support is required over 18 ft. The Barrier base construction is made out of heavy structural steel with a heavy base plate that can be bolted to concrete or any solid base. The MB832 can also be bolted to a movable concrete or heavy steel base to allow it to be portable. The base unit is finished with orange power coating.
Multiple steel counterweights of two different sizes are used to counterbalance the arm for easy operation, but it is recommended that barrier gates used many times a day be limited to a 24 ft arm length for continuous operator ease of use.
The pivot assembly requires no maintenance and is constructed of stainless steel hardware and high density plastic bushings.

Manual Barrier Gate Arm:
The arm can be locked in up or down position with a simple padlock.
The steel counterweights can be easily field adjusted to make the aluminum arm default to the up or down positions. Also the counterweight adjustment can control how fast or slow the aluminum arm rises or falls.
The aluminum barrier arm is heavy extruded aluminum with a white powder-coating, it comes supplied with DOT reflective tape as pictured. The arm allen bolts and washers are also stainless steel.
