Each order of 1 (one) is for 1 (one) Kit 

What's in the box:
2 poles
2 u-bars
1 piston 

This is truly a conversion kit... so you need to have a Cover Caddy in stock to be able to convert it. Also, keep in mind that most swim spas require two cover lifters, so you'd need 2 - Cover Caddy lifters and 2 swim spa conversion kits.

No Lifter is included with this item: Please see: Cover Valet - Cover Caddy Premium Hot Tub Cover Lifter

Here is how it works:

Swim spas tend to be too high for the Cover Caddy to reach the top of the acrylic using the stock parts that come with a standard Cover Caddy. So the swim spa conversion kit contains an extra long set of legs, an extra long set of arms to stow the cover, and a stronger shock to accommodate the extra weight/leverage of such a large tub. So after a conversion, you will be left with a few extra regular Cover Caddy parts (2 legs, 2 arms, and a shock) that have been replaced by their swim spa counterparts.

Swim Spa Conversion Kit available for spas 41 inches to 60 inches tall
