Endless Pools E Series CoverCradle Spacers

The CoverCradle is a recommended, high-end, hydraulic lift accessory for Endless Pools E-Series Swim Spas, designed to make opening and closing the cover easier. 

Based on typical installation requirements for this type of spa lifter, here is the information regarding spacers and fit:

Necessity for Spacers: Because Endless Pools E-Series swim spas often have specific cabinet depths, corner radii, or, in some cases, partially recessed installations, spacers may be required to ensure the bracket mounts properly and clears the cabinet structure.
Availability: Spacers are generally provided within the CoverCradle installation kit (specifically designed for Hot Spring/Endless Pools models) or are available through authorized Endless Pools dealers.
Function: They ensure the hydraulic arms are correctly aligned for the "ultra-smooth gliding action" the CoverCradle provides.
