Bail Shells
Jennmar's conventional bolts consist of a shell anchor headed smooth bar with a consistent threaded end. A bearing plate is also used to provide increased strata control. Jennmar offers several types of shell anchorage systems. Our bail anchors have full shell-length contact (less contact pressure) and work well in weak strata conditions. Like all of our products, each system is inspected upon arrival from the mill and then re-inspected upon shipment from our manufacturing facilities.
All systems are configured with high strength bar:
- Grade 55 (55,000 psi minimum yield)
- Grade 75 (75,000 psi minimum yield)
