Pro and EDR?

Can a high strength vex pro locking collar be used in EDR competitions?

According to the VEX Pro home page ( ), it states that the products are for FRC. This means that the VEX Pro Locking Collar would not be considered legal for use in VRC, unless you are in VEXU, which the VEXU Appendix specifically states that VEX Pro Products are legal.

So, how would a high strength collar get locked into place?

On the page here: under “High Strength Shaft Hardware,” you can see “High Strength Clamping Shaft Collar (10-Pack).”
