Place your ladder on the roof rack and align a ladder rung with a front or rear rack.

Place The Ladder Locker's L-shaped feet over the ladder rung with and feed the stainless-steel embedded strap under the rack and around the ladder rung.

Feed the strap into the easy glide cam below the lock and then push the strap into the sleave all the way through and pull it tight.

Depress the rapid tension lever, which both tightens and locks the strap, firmly securing the ladder. 

Push the button lock to secure your ladder.

To remove the Ladder Locker, release the rapid tension lever and use the key to unlock it. Depress and hold the release button on top of the hood with one hand and pull the strap with the other to remove it.
