I need to replace my skimmer lid on my older hot tub. Which is the correct one?

We have two skimmer lids available. For hot tubs 2002 to present the correct skimmer is # 3002708. For hot tubs prior to 2002 the correct skimmer is # 3002704. If you have any doubts which one you need, reply here with your hot tub serial number so we can confirm the year of your hot tub and to verify the part you need.
