Eclipse Bolting System

The Eclipse System was developed by Minova USA Inc. formerly Fosroc Inc. to improve the performance of 5/8-inch deformed rebar fully grouted into a one inch borehole. An 1/8-inch offset bolt head combined with specially formulated Eclipse Lokset resin cartridge results in reduced gloving and increased mixing efficiency. The benefits of the Eclipse System have been demonstrated, under the supervision of MSHA, in Kentucky, West Virginia and Illinois coal mines in partnership with Excel Mining Systems, a leading roof bolt manufacturer. Over 100,000 units have been installed to date. Eclipse system bolts exposed during overcast construction at the Panther Mine of Cumberland Resources displayed an extremely well mixed, uniform resin anchorage over the entire bolt length.
