ATTACH 111931 CASTORS TO 30R1904D RAFTER PIPES
Basic Assembly Notes to Attach Castors to Rafter Pipes:
One way to prevent misalignment of the castors and roller track is to attach the castors to the 30R1904D rafter pipes then
slide the rafter pipe into the ends of each assembled rafter during frame assembly. Preview the frame assembly steps for
additional information.
Gather the parts:
• Rafter Segments – #30R1904D
• Metal Castors — 111931
• Wrenches to tighten castor mounting bolt.
Complete these steps to attach the castors to the 30R1904D rafter sections:
1. Take one castor and remove the bolt, nut, washer, and angled safety guard.
2. Slide the mounting bolt of the castor through the mounting hole of the rafter segment as shown and add the metal
castor. Verify that you have positioned the castor on the correct side to the rafter segment. See next page diagrams.
3. Reinstall the safety guard, lock washer, and nut.
