The CR-3000-UDB Universal Door Bar is an accessory for use with the Workhorse CR-3000 Car Rotator. These guys at Workhorse have thought of everything. Most vehicle bodies and components will be able to easily be mounted to the CR-3000, but for those special situations, you need an adapter. That's where we come in. We've got virtually every accessory or adapter you could possibly need. This universal door bar is compatible with nearly every door on the market and is as durable as the rotator.
