Taken from the Jegs website.
Used primarily for drag racing to provide positive locking action to the front wheels of race cars, reducing the chance of ''Rolling the Lights'' and producing more effective burn outs for heating up the tires. Rigorous testing has proved a 1/100,000 of a second release time and vibration tests have seen up to 30 G's applied without mechanical failure. On the street or off-road, and as a temporary ''Hill Holder'', roll control (line lock) finds use when both the clutch and brake are needed at the same time. With the on/off button at the control of the driver's fingertip, release of the locked wheels is easy.

This product is also referred to as: Stage Control, Line Lock, Line Loc, Launch Control, Anti-Roll, Brake Control and Roll Stop. These are essential race car parts.

Basically it's a solenoid valve and a switch to activate the valve. It goes into the brake line feeding the front brakes. You step hard on the brakes, activate the switch, then take your foot off the brakesw which releases rear brakes, but holds the front brakes until the switch is released.
You can see the soleniod below the master cylinder on my gasser here:
