Product Catalog

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 and work well in weak strata conditions.

T-Channels, Roof/ Rib Safety Channels, Roof and Mini Monster Mats

All systems are configured with high strength bar: - (Grade 55 (55,000 psi minimum yield) - (Grade 75 (75,000 psi minimum yield)

The Fast Anchor 3 is a double corrosion-resistant steel bolt for strata control that provides quick assembly and secure installation due to its expansion shell that provides immediate anchorage and generates superior grip upon application.

The JENNMAR FRICTION-LOK Stabilizer System is a strata control system designed to firmly control hard or soft rock. As lateral ground movement increases, the system increases its superior holding power.

Forged Head Rebar and J-BAR

The J-LOK resin in the cartridge is used to anchor bolts to the surrounding strata. This unification of the resin, bolt, and strata layers provides the necessary strength and rigidity to prevent sag by acting as a reinforcement that anchors the individual stratified layers of rock into a single high strength beam.

Wide range of applications including rock bolts, rock dowels, rock spiles, soil nails, micro piles, etc.

M3 expandable rock bolts offer superior quality that responds to the most demanding roof support applications. Its high load capacity and excellent elongation properties ensure safer working conditions and faster excavation cycles.

Available in hydraulic or electric pumps.

Jennmar plate products feature high strength, lightweight, and a low profile, effectively distributing roof bolt load evenly in all directions. Manufactured under rigid quality - control conditions in accordance with ASTM F432, plate ratings range from 20,000 to 60,000 lbs. Customized sizes and coatings are available.
