215" x 94" Swim Spa Cover for H2X Trainer 18 and MP Signature
This 215" x 94" Master Spas OEM replacement cover is built for H2X Trainer 18 and MP Signature swim spas, offering superior insulation and durability.
This 215" x 94" Master Spa Factory OEM swim spa replacement cover is made of energy-efficient six-inch foam insulation that tapers down to four inches along the sides, and features a 1.5 lb. foam density — all of which helps prevent significant heat loss from your swim spa! It’s crafted from high-end marine-grade vinyl that helps resist mildew, UV damage, and more.
Additional replacement cover highlights include:
- EPS Foam Cores With Taper – As noted above, this 18' x 8' replacement swim spa cover features 6" foam insulation that tapers to 4", along with a 1.5 lb. foam density to help prevent moisture from seeping into the cover over time.
- Full Length Heat Seal – The full-length heat seal helps lock in your swim spa’s heat by minimizing escape points. A 12 oz. chemically resistant vinyl scrim adds extra durability to the outer edge.
- Three Panel Skirt Design – This design improves heat retention and also helps block outside debris, dirt, and weather from getting into your swim spa.
- Two Upgraded Rubber Grip Handles – These easy-to-grab rubber handles make it easier to lift and reposition your swim spa cover without slipping — a helpful upgrade over standard handles.
- Four Release/Lock Hardware Connections – Built-in locking straps help keep your cover secure in windy conditions or when your spa is not in use.
- Galvanized Steel Brackets – Reinforced steel brackets provide added structural strength and reliability to the cover’s core.
- Bottom Vinyl – The underside of the replacement cover features an 11 oz. reinforced weft, mildew-treated bottom vinyl that adds durability and protection against spa moisture.
- Double-Stitched Reinforcement – With 27 key points of reinforcement, the double stitching helps provide long-lasting structural support and resistance to wear and tear.
- ASTM Certified for Safety – This cover meets ASTM safety standards when properly installed with a locking system.
- 18 Color Options – Available in 18 colors, which can be previewed in the swatch images above.
