Perfect fit

I found this to be a perfect replacement for my swim step compartment / built in cooler drain on my 2009 Tahoe Q5i.

Live well overflow

Using the 1 1/8 fitting with matching overflow drain tube in kayak live bait well. Can be cut down easily to fit thin polyethylene and fiberglass structures. Nicely paired products.
