as the lever only has a limited amount of travel on the wheel you are using, if it won't stay tight enough in the locked position, you just screw the bottom "wheel" in a touch, then re-attach the lever with the three screws shown in three other holes that align with the adjuster slot in the steering wheel. there are 6, threaded holes in the wheel below on some columns, and on others, there are slots on the adjuster lever "hat" [as shown in the lead in picture], that can be realigned with the holes in the lower wheel after it is slightly tightened. the slots will be in a different position then, allowing you to position the locking lever at the unlock position, and still move it to "lock", with more clamping force on the locking rod, keeping the wheel where you need it to be, while still allowing the rod to be loose enough the spring under the outer can on the upper column [under the steering wheel, usually stainless, although i have come upon painted ones before] easily helps the steering wheel extend to the desired height. i know this sounds more complicated than it actually is, but if one tears into a tilt/telescope column, it quickly becomes apparent how these things work.
