# Cascade Pulley Blocks

{% hint style="info" %}
The Cascade Pulley Block are not needed for the Single Stage Elevator Assembly.
{% endhint %}

The Cascade Pulley Blocks can all be assembled before the rest of the elevator. If you are assembling a 1 Stage Elevator, this section can be omitted. Four Cascade Pulley Blocks are required for all extra stages.

{% hint style="info" %}
Equal amounts of both assembly configurations pictured above are needed. This is to prevent the #10-32 nut from colliding with other parts of the elevator.
{% endhint %}

## Step 1

Assemble the pulley, bushings, and spacer as shown in the image below.

## Step 2

Slide the assembly from step 1 into the Cascade Pulley Block as shown in the image below. When the #10-32 x 1-3/4"L bolt is fully tightened, make sure the Pulley spins freely in the assembly.
