Matthews manufactures a number of stands, both rolling and non-rolling such as the Baby Junior Stand in both double riser and triple riser. Century Stands, Matthews Kit Stands, and Beefy Baby Stands are all manufactured with a Baby Pin at the top. Matthews Combo Stands are now made with a Baby Pop Up Pin for greater flexibility.

Both black and white will give you reduction of light intensity and white will introduce ambient bounce.

Drop Down

The bBaby Drop Down is made with a female 5/8″ receiver at one end and a baby pin at the other. In between is a hinge which when added to the end of a light boom allows the light fixture to stay level regardless of the angle of the boom.

The 45 degree Angle Drop Down mounts on a Combo Stand and allows a reflector to be used at a low angle without the Yoke or Bale creating a shadow.

The term Junior is used when referring to a 2000Watt or 2K light fixture. The standard Junior is made with a 1-1/8″ Pin attached to the Yoke or Bale, and therefore gets mounted into a female receiver on the stand. It is the opposite of the Baby mounting system for safety purposes. Lighting fixtures larger than a 2K also have a Junior Pin.

Meat Axe

Originally designed for use on studio catwalks; it is now commonly used in television studio grids. The attached C-Clamp mounts on the grid or railing of the catwalk, and allows the mounting of a flag or cutter via its 2-1/2″ Grip Head. For safety reasons, neither the arm nor any of the attachments are removable.

Menace Arm

Menace. A noun. 1) Something that threatens to cause evil, harm, injury, etc.; a threat: Air pollution is a menace to health. 2) A person whose actions, attitudes, or ideas are a menace. In movie terms, a menace arm is just what the word describes. A menace. A possible danger; a threat.

Before MAX, 

a Menace Arm was a jury-rigged arm usually built on set and used to place a light or camera in an otherwise difficult position. This was not only very time consuming to build and very dangerous if not constructed or used properly.

Hence the Max Arm designed by Key Grip Richard Mall and built by Matthews is safe and time efficient, capable of lifting and placing a light or camera from a negative six feet to positive 17 ½ feet with a horizontal reach of 17 feet.

Mombo Combo

Redesigned for greater strength and safety the new Mombo Combo is capable of reaching new heights. At its full extension of 27 feet, we strongly recommend the use of the new Guy Rope set that is now available and Anchor Pins if no other safe attachment is available.
