I didn't weigh it but I would guess around a gram or two. The AT cartridge started off light at 6.5 grams, so the extra weight was a non-issue.
My best guess is that it tamed the resonating frequency and created a better bond between the cartridge shell and the arm. Without running test it is hard to actually say why it improved the sound but it did. Also, it didn't cost more than a dime to install since I already had some along with a heat gun. If I didn't like the results I could just remove it.
I would caution others to beware of the high temperature of the heat gun. You don't want to transmit the heat to you cartridge or directly heat other parts that could be damaged.
I wish that I had a Grado Platinum to see how much better the table would sound with an even better cartridge than the cheap AT. Before the wrap I put the Glider on the table and noticed an improvement so I would assume that the wrap would even allow better performance now. Maybe I can try it out with the Glider/wrap before sending it out. If only the clips on the WTRP were less fragile so I didn't have to worry about breaking and resoldering them.
