For new push-on pipe bell installations

The rings, wedges, and actuating bolts are made of high strength ductile iron in accordance with ASTM A536 Grade 65-45-12 requirements.

The modified PVC Stargrip® has a larger bolt circle diameter to increase clearance.

The product uses larger diameter rods so fewer rods are needed to achieve its pressure rating. Fewer rods mean less hardware to assemble. The safety factor is twice (2:1) the product pressure rating.
