HST cover for Bullfrog A7 / R7 / X7 – 88 x 88 in, 2013–2022

This 88 x 88 in black Pro-Tex HST replacement cover is offered for compatible 2013 to 2022 Bullfrog A7, R7, and X7 spas. Its 5 to 3 in slope, full thermal seal, and welded 6 mil vapor barrier help preserve heat when the spa is closed. Its two rubber handles make it easier to grip when handling.

Choose the right cover for your A7, R7, or X7

This 88 x 88 in square configuration is intended for the compatible models and generations indicated. Successful replacement also depends on the corner shape, skirt length, and fold direction. Do not extend the stated application to a model from another generation without verification. If you use a lifter, also compare its attachment points with the new cover.

A 5 to 3 in slope and a full thermal seal

The profile, measuring 5 in at the center and 3 in at the edge, promotes water runoff. The full thermal seal and overlapping skirt help limit openings around the perimeter and at the center. The welded 6 mil vapor barrier protects the interior against moisture transfer. Fit and maintenance affect heat retention; no quantified energy savings are claimed.

Black Pro-Tex: an outdoor fabric

HST describes Pro-Tex as solution-dyed polyester with a polyurethane coating for surface protection against water. The materials are treated against UV rays and resistant to mildew. Pro-Tex fabric is advertised as 25% lighter than vinyl; this applies to the covering and not the total weight of the cover.

Confirm the corner radius and skirt length

This configuration has corners with an 8.5 in radius and a 7 in skirt with overlap. Compare these measurements with the current cover, then check the fold direction and fasteners. Provide the exact spa model and year to confirm the fit, particularly if the cover has already been replaced.

Installation, handling, and maintenance

Place the cover evenly on the spa and check the support and alignment of the fasteners. Gently release the seal before lifting with the handles; the skirt is not a handle. Clean with a soft cloth, water, and mild soap. Carefully remove snow buildup with a broom, not a shovel, and drain standing water to preserve the cover’s shape.
