About this ARRI Quick Guide
This Quick Guide (order number K5.44285.0) provides a short introduction to the ARRI MB-20 Compact Matte
Box. It is essential that you acquaint yourself with this guide before operating the equipment.
Even though all efforts have been made to ensure this guide’s accuracy, changes and upgrades to the
products described can result in different hardware or behaviour. Technical data are subject to change
without notice.
This document can be downloaded from www.arri.com in Acrobat pdf format. The Acrobat Reader can be
downloaded free from the Adobe web site at www.adobe.com. A PostScript printer gives best printing results.
Tools
Anyone operating the ARRI MB-20 system should have a 3 mm metric hex wrench which is used to fine tune
the vertical orientation of the MB-20 with the Swing-away Module fitted.
Safety Specifications
• Assembly and initial operation should be carried out only by persons who are familiar with the equipment.
• Repairs should be carried out only by authorised ARRI service centres.
• Use only original ARRI replacement parts and accessories!
• Do not remove any screws which are secured with paint.
MB-20 System
The ARRI MB-20 Compact Matte Box is a versatile, modular matte box designed primarily for the high
definition video market, but can equally well be used with 16 or 35 format film cameras. Interchangeable
modules allow for either rod mounted, swing-away operation or for clamping directly onto the lens.
The heart of the matte box is the Basic Module, in front of which can be fitted the removable Sunshade and
Top, Bottom and Side Flags. Interchangeable Hard Mattes can be snapped into the front of the Sunshade.
The back of the Basic Module accepts a 2 or 3 Filter Stage – all filters are individually rotatable.
The right-hand edge of the Basic Module mates with one of 2 support systems:
• Check recent price lists and Configuration Overviews for new parts not yet in the MB-20 program at the
time of printing of this Quick Guide.
The Clamp-on Adapter
In this mode the matte box clamps directly to the front of the lens. The Clamp-on Adapter used alone fits
lenses with a front diameter of 130mm. A range of Adapter Rings reduces the basic 130mm diameter down to
as little as 80mm to work with a wide variety of lenses.
The Swing Away Module
The Swing Away Module offers all the features of a production matte box, where the matte box is mounted on
support rods and the entire front section swings forward to facilitate lens changes. To the Swing Away Module
is fitted either the Console for Lightweight Support or the Console for 235 Side Bracket. The Console for
Lightweight Support mounts directly on 15mm Lightweight Support Rods or, with the addition of an adapter,
onto 15mm or 19mm studio support rods. The Console for 235 Side Bracket allows the matte box to be used
with an ARRIFLEX 235 fitted with Side Bars.
In Swing Away mode the rear of the filter stage is fitted with the Back 138mm Bellows Adapter. This accepts
a selection of 138mm and 4 ½” Filter Rings, which offers the addition of a further, round, rotatable filter. The
filter rings combine with Connection or Adapter Rings to work with lenses of different front diameters. (See the
Configuration Overview on pages 2 & 3 of this guide for details).

The Basic Module
The Basic Module is the core plate of the Matte Box in front of which the sunshade and flags are mounted.
Behind it is fitted either a two or three stage filter holder. One edge has two mounting holes which allow either
the Clamp-on Adapter or Swing Away Module to be fitted.
The Filter Stage
Basic Operation
Fit the cut-outs on the front of the Filter Stage over the corresponding tabs on the back of the Basic Module in
the position shown, and then slide it into the central position until it locks in place (1). To remove it again, pull
the filter release lever forward (2) and reverse the procedure.

Combo Filter Trays
In addition to conventional 4” x 5.65” filter trays in both horizontal and vertical orientation, the MB-20 offers two
Combo Filter Trays. These are designed so filters of more than one size and shape can be used.
Combo 2
Holds 5.65” x 5.65” square filters or 5” x 6” filters.
Combo 1
Holds 4” x 5.65” filters horizontally or vertically or 5” x 5”
square filters.
The Clamp-on Adapter
To fit the Clamp-on Adapter to the Basic Module, ensure the slide lock lever is unlocked, and slide the Clamp-on
plate back fully on the rods (1). Engage the two mounting pins into the holes on the Basic Module. Press fully
home (2) and tighten the two blue clamp knobs (3). Now slide the Clamp-on Plate forward and secure it to the
back of the filter stage with the locking screw (4). Finally tighten the slide lock lever (5).

The Swing Away Module
Engage the two mounting pins of the Swing Away Module into the corresponding holes in the Basic Module, press
fully home and tighten the two blue clamp knobs. To remove the Swing Away Module, loosen the blue clamp knobs
and it is then necessary to pull the black horizontal adjuster out of engagement with the mounting pins before they
can be withdrawn from the Basic Module.
Back 138mm Bellows Adapter
Fit the Back 138mm Bellows Adapter over the two locating pins and secure with the two blue lock screws.
The red rotation lock either releases or locks the rotation of the complete bellows adapter along with any filter
mounted in the bellows filter holder.

Console for Lightweight Support
The Console for Lightweight Support attaches to the Swing Away Module and allows the matte box to be
mounted on 15mm lightweight support rods. When the correct distance from the camera has been set tighten
the lock screws to lock the console to the rods.
Adapter for 19mm or 15mm Rods
To use the MB-20 with a bridge plate and either 19mm or 15mm heavy duty support rods, an adapter needs
to be fitted to the bottom of the Console for Lightweight Support as shown above.

Vertical Adjustment
The Swing-away Module is attached to either the Console for Lightweight Support or the Console for 235 Side
Bracket by two M4 screws. Between these is an adjuster for the vertical alignment of the matte box. To operate
this adjuster, use a 3mm hex wrench to loosen the two M4 screws slightly before using it to rotate the adjuster.
Once the desired alignment is achieved, tighten the two M4 screws.
Horizontal Adjustment
Before tightening the blue clamp knobs, the horizontal position of the matte box can be fine tuned by rotating
the two black horizontal adjusters (top one only shown). Once the desired alignment is achieved, lock the two
blue clamp knobs.

Top Flag
The Top Flag is held onto the Basic Module by two lock wheels, as shown above. It can be adjusted and fixed
in position by tightening the lock-off knob at one end. If desired, the Top Flag can be attached underneath the
matte box to form a bottom flag.
Side Flags
The two side flags are identical. They attach to a single lug on either side of the Basic Module. The top and
bottom edges are adjustable.
