ALZO Wall Mount Background Support Assembly and Installation guide

The ALZO Wall Mount Background Support System consists of parts as shown here:

1. (2 or 4) 3 position Wall Mount Support Brackets Hooks
   
2. (3, 4, 5 or 6) Sets of plastic pole ends
3. (3, 4, 5 or 6) Sets of adjustable chains
4. (3, 4, 5 or 6) Sets of 2 section aluminum poles

The installation of this system requires a minimum of 2 individuals and a licensed construction professional is recommended.

IMPORTANT NOTICE: Proper Friction Adjust is required to prevent background roll-out. Over tightening the friction adjust will cause problems and will DAMAGE the chain drive.  We will not be responsible for damaged chain drives resulting from improperly adjusted Friction Adjust.

The bracket mounting hole spacing

• For 10 foot wide = 123 +/- 1 inch
  
• For 6 foot wide = 75 +/- 1 inch

As the weight supported by this system is heavy, it is recommended to either BOLT into framing or fasten into a solid wall structure like a concrete block wall.

When attempting to mount on drywall or wallboard, please contact a hardware vendor or licensed contractor to procure appropriate fasteners for very heavy loads.

You will be installing 4 of the 3 position hook sets with 4, 5 and 6 poll background support systems.

Step 2: Join the horizontal poles

The pole junction needs to be re- positioned to join the poles. The junction is located in the end of one of the 2 poles.  Insert the L-HEX KEY (Allen wrench) into the hole where the junction is located and loosen the set screw to reposition the junction so that 50% of the junction is exposed and the pole hole aligns with the set screw. Now with the L-KEY remaining in the junction set screw to prevent movement of the junction, join the 2 poles together.  Align the holes in the pole junction and the poles and use the L-KEY to tighten the 2 set screws as shown below. Tighten the set screws in alternating small tightening steps (1-2, 1-2, 1-2, ...) until both set screws are very tight.

Step 3: Assemble the Roller Ends into the poles and mount poles

There are 2 different plastic ends that fit into the poles and then fit into the bracket hooks. Shown here is the chain drive end. The other end is the Friction Adjust end.

Insert the white plastic expansion clamp into the pole end as shown here and tighten the clamp by turning the knob clockwise while holding the chain guard.

Proper use of the FRICTION ADJUST

IMPORTANT NOTICE: Proper Friction Adjust is required to prevent background roll-out. Over tightening the friction adjust will cause problems and will DAMAGE the chain drive.  We will not be responsible for damaged chain drives resulting from improperly adjusted Friction Adjust.

When background paper is installed on the pole it is important to rotate the wing nut on the friction adjust end to prevent paper roll out when lowering the paper. This is accomplished by adjusting the friction adjust while rolling out the paper to the floor.  Set the friction adjust so that the when the paper is near the floor the roller is stationary. Tightening the wing screw on the friction control will add resistance to the rotation of the roll.

The plastic ends can be installed on either end of the pole. Once both ends are installed on the pole, the background paper or fabric can be installed by removing the friction adjust end, sliding the background over the pole and then re-installing the friction adjust end

After the paper is on the pole, the pole is lifted into position and inserted in the hooks on the brackets. This operation requires 2 persons, and is nearly impossible for an individual to accomplish.

The pole will now be tightened on the plastic ends by holding the pole with one hand, and then tighten the 2 knobs on each end until the ends are locked onto the pole.

Step 4: Adjust friction

Proper Friction Adjust is required to prevent background roll-out. Over tightening the friction adjust will cause problems and will damage the chain drive  Tighten the wing screw on the friction control to add resistance to the rotation of the roll. Roll out the background until it is near the floor. Now loosen the friction adjust until the background starts to un-roll. Stop the unrolling of the background and tighten the friction adjust so that the background rolls easily with the chain and does not auto unroll when rolling out.

Do not tighten the friction adjust to lock the rotation.
Do not loosen the friction adjust to allow background roll-out.

Step 5: Install wedges

Insert a plastic wedge into the space between the paper center tube and the pole on both ends of the roll. Push in wedge until firm. These wedges are required to lock the paper to the pole and to prevent paper roll out.

2 wedges per roll are provided and you can insert 1 on each end of the roll.

Step 6: Install chain

Insert the plastic chain through the sprocket end and adjust the length of the chain, as desired, by removing and adding links. Chain links are separated by holding 2 links in a V form and sliding them sideways.

Note the horizontal orientation of the gates around the sprocket. There are 2 mounting options for the chain drive end fitting into the bracket hook. Select the mounting option that positions the gate around the sprocket horizontally.

Step 7: Install chain weights

Add the chain weights as shown to the hanging end of the chain. Chain links are separated by holding 2 links in a V form and sliding them sideways.

At this time you may want to re-adjust the friction control to provide a smooth rolling action and prevent background roll out.

Installing fabric backgrounds requires using 2 inch wide gaffers tape on the ends of the fabric securing the fabric to the poll.
