Invade Hot Spot 24 Inch Hose Extension Actuator Flexible To Apply Invade Foam

Will use with hot spot to put foam deep into drain to remove mildew and crud buildup in drain.

I don’t see how you could use the spray foam with out it.

I like the length of this tube and it works ok in the bathtub but I need it more down the kitchen sink and it doesn't fit down the drain.

Don't throw away the original top unless you want to be stuck with the long tubing top to store.

Worked well on the drain - did not come with an extender and that I had to be separtely. They could have included even a cheap one.

A little pricey but it did the job.

Expensive

I flipped the top of the part that attaches to the can, put it on the spray button and can't get it to attach. There was foam EVERYWHERE.Just use the straw that comes with the can.
