Parallel Through:
This joint can connect to any straight vertical bar on the wheelchair. Zip tie it to the bar with the 3 premade trenches. Then a 3/4" PVC pipe can slide all the way through on the other side. This allows for additional support in locking down the frame of the costume to the frame of the wheelchair. 

Parallel Through Capped:
This joint can connect to any straight vertical bar on the wheelchair. Zip tie it to the bar with the 3 premade trenches. Then slide a 3/4" PVC pipe in front down to the capped off bottom of the joint.   

Parallel Capped:
Similar to the "Parallel Through Capped" joint, this is used in the same manner, but doesn't surround the PVC pipe and instead lets it sit on a shelf. The PVC pipe can still be secured with zip ties. 

Long Tee Joint:
This joint can serve as a pivot point by attaching onto a PVC pipe side. The two trenches are for zip ties to secure it down and not slide off the joint. Then slide a PVC pipe into the top and use the tiny holes to screw into the pipe and lock it in place. 

Caster Wheel Attachment Joint:
While this is most commonly used for caster wheel attachments, it could be used for other things too. This is if you need to attach the end of a PVC pipe to a flat surface such as a piece of wood. It has four screw holes for base and two screw holes to secure the PVC pipe into it. 

Wheel Caps for Small Stroller Type Wheelchair:
These wheel caps allow for a wheelcover to go over the back wheels of a stroller type wheelchair with mag wheels. The graphics for those wheels can then stay upright at all times by using ballbearings and weights at the bottom of the design.
