The Xtreme line is our strongest and most durable line of parts. The Xtreme Dual V Wheel Kit Wheel is designed for strength and reliability. These can be used with the OpenRail System and V-slot extrusions. Note that it is a wheel only, not a wheel kit.
With these low-profile self-tapping screws, you can easily build a boxed frame out of V-Slot corner connectors. You'll have your frame built in minutes! No more need for tapping - these screws make it quick and easy.
