Top 4 Questions:
When do you need an arm support?  
A tip support or cradle is needed for arms over 18ft 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 str
eet .
Can the barrier gate arm be locked?
The arm can be locked in up or down position with a simple medium size padlock.

The Manual Barrier MB832 is designed for outdoor use when a heavy duty dependable maintenance free solution is required.
It can be use for guards to control traffic at an entry point or it can be used occasionally for blocking of roadways and parking lots up to 32 ft in length.
Two MB832s can be used at opposite sides of the roadway to cover a maximum of 64 ft. If the arm is damaged it can be easily replaced without special tools.
All MB832s are fully assembled at our factory and balanced for the arm used. All that is required is the bolting in of the arm at the jobsite.

General Information:

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 after 18 ft.   tip support or cradle
Barrier base construction is made out of heavy structural steel with a very 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.

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.
