Sundance Hot Tub Plug

thingiverse

Sundance brand hot tubs usually feature two holes, one on each side, for wiring purposes. The unused hole typically comes with a flimsy plug installed. To prevent pests from entering, replace this weak plug with a more secure option. This new plug stays in place effectively; however, applying a small amount of clear caulk ensures it is extremely snug. I used this on my Sundance 780 series hot tub, but it should work on most models since the conduit size is standard.
