<div style="margin: 0in 0in 0pt">HL metal and plastic tracks disassemble the same way. I'm assuming yours has pins, correct?I push the pins out with one straightened end of a paper clip. You have to press on the pin end that faces outside when installed on the tank because the inside end is where the knurled retention nub will be which keeps the pin in the track. Some pins are stubborn tho, and when you find one that is, just move on to the next one. Most push out fairly easily. HTH. </div>
