Model #4 + PUCK: Adjustable Height 2 3/4" to 3 1/8".
All the PUCKS (SOLID ROUND BASE) sure do add some weight to the TRU-LIFT sleeves.
*Please note that these are only recommendations according height requirement provided the turntable is @ original factory settings without any upgrade.
How to determine which TruLift you need:
Measure from the plinth to the UNDERSIDE of the tonearm with the needle sitting on the record near the run out groove / label
