Product Overview

The CoverMate III DeckMount (CMIII‑DM) by Leisure Concepts is a premium hydraulic cover lifter designed for fully recessed or sunken spas surrounded by decking. It's specifically engineered to mount directly to the spa deck instead of the cabinet, making it ideal for flush-inset installations where traditional lifters won't fit.

It requires only 6 inches of rear clearance and 5 inches on each side, making it suitable for tight spaces and narrow deck environments. Integrated dual hydraulic gas shocks make lifting and lowering the spa cover effortless and safe for one person, and it's constructed with powder-coated aluminum and non-corrosive composite mounting brackets for long-term durability in outdoor conditions. It includes the TowelMate accessory for hanging towels or robes and features WindLock technology to prevent cover slam in windy conditions, and fits square and rectangular spas up to 96″ wide with a maximum corner radius of 12″.

  • Confirm that your spa is fully sunken or flush with a surrounding deck and does not have an exposed cabinet for side mounting.

    Measure and mark bracket locations approximately 6 inches from the back edge of the spa and centered vertically against the deck frame.

    Secure the mounting brackets directly to the deck surface using lag screws or bolts appropriate for your deck material (wood or composite).

    Assemble and attach the lifter arms, center coupler, and hydraulic shocks according to the instruction diagram—ensuring the gas shocks are oriented with the cylinder (body) on top.

    Attach the cover lifter bar and ensure alignment with the spa cover’s fold seam.

    Install the WindLock safety system and optional TowelMate towel hanger.

    Test the lifting motion, adjust tension and bracket position if necessary, and tighten all hardware fully.
