Those are the Locking Bike Trac from Saris. The loop for a U-lock makes them a special-order, commercial parking garage thing. I have to special order them at the LBS (about $80 each, +shipping, and boy are they heavy) and wait a couple of months for them to come in. But, I won't leave an unlocked bike home alone in my apartment. The only bike I ever had stolen was stolen from my locked storage bin in the locked basement at my old apartment. That won't happen to me again.

Less paranoid people will do just fine with the plain old ordinary Bike Trac from Saris. They're half the price and your LBS can order it from QBP.

I prefer the trac style to plain hooks because they keep wet tires off the wall.
