This section is only needed for 3+ Elevator assemblies.
Before assembling the Extra Stage Horizontal Tube, drill the threaded holes on the Aluminum Tube Plugs marked in green. Both sides must be drilled. Then, assemble the Extra Stage Horizontal Tube as shown in the image below.
The bolt heads for both Pulley Blocks must be facing towards each other.
Assemble the Extra Stage Cross Tube as shown in the image below. Make sure not to crush the tube when tightening the #10-32 x 1-1/4"L bolts.
Bolt the Extra Stage Vertical Tubes to the assembled Extra Stage Horizontal Tube. When assembled, the heads of the #10-32 x 1-1/2"L bolts will sit inside the Elevator Block.
Make sure to install the Bearing Blocks with only one of the 3/4" OD Radial Bearings.
Attach the assembled Extra Stage Cross Tube to the Extra Stage using four #10-32 x 5"L Bolts and 2-1/2"L Spacers. While it can be lower, it is recommended to mount it as high as possible to increase the strength of the Extra Stage.
Mount both Chain Attachment Brackets to the bottom Extra Stage Horizontal Tube in the orientation shown below. The brackets will be installed using six #10-32 x 2-1/2"L bolts and #10-32 nuts.
If you are assembling an elevator with 4 or more stages, these brackets only have to be mounted to the 1st stage after the Elevator Mast.
