Quality built product The switch came with a mounting bracket (to attach the switch to a pump) and mounting clamp (to attach the switch to the mounting bracket) but the clamp for mounting the bracket to a pump was not included but that's expected as there are hundreds and hundreds pumps and it is impossible to include a clamp for all of them.

This switch is 3/4" differential meaning that there has to be at least 3/4" inch of water from the bottom of the switch

Anyway, I was pairing this switch with a Rule 10, 2000 GPM pump and purchased a size 48 clamp which fit perfectly. Once all mounting clamps are tightened, the attachment between the switch and the pump felt very solid. Additionally, my install was for a secondary pump and I ran all new plumbing for it as joining to existing plumbing would sacrifice the whole purpose of the secondary pump and redundancy. I got Attwood Stainless Steel Barbed Short Length Straight Thru-Hull, 1 1/8-Inch, M3 4200 adhesive, and size 12 hose lamps for the hose. I bought the hose at West Marine as finding smooth-walled hose wasnt as easy as I thought - everyone sold corrugated hoses and those reduce the flow by as much as 30%.

Installation took me couple of hours stretched between 2 days to allow the adhesive to cure properly.

Kicks on and works hard when needed. Well worth the $$$

Excellent
