	530 SUPER SPHERE BENEFITS
	*Spherical Arch* Utilizes a "flowing arch" design which provides more movement in comparison to narrow or filled arch/spool-type joints. The "flowing arch" is also self-cleaning, which makes it a perfect choice for slurries and turbulence reduction. It also eliminates the requirement for specifying a "filled arch".
	*Increased Flexibility* • 30% increased compression movement • 15% reduction in spring rates compared to standard expansion joints. • An alternative to multiple arch designs.
	*Improved Sealing* A full-faced rubber flange reinforced with fabric provides optimum sealing. Other competitive products are molded and sometimes only have a small lip/bead area for sealing.
	*Less Weight* Weighs up to 50% less - for ease of handling and reduced freight!
	*Less Cost* Exclusive synthetic, high tensile radial cord matrix is used in manufacturing the 530 SUPER SPHERE . Our proprietary construction eliminates the need for internal metal body rings while still providing adequate pressure and vacuum ratings.
	*Customer Service* The Holz Expansion Joint experts are at your service 24 hours a day, nights, weekends and holidays.
	*We're on-line all the time - to help you with your requirements.*
