L Anchor 
 L-type resin without longitudinal ribs bolt steel bolt, high strength, reasonable structure, preload force, able to automatically adjust the direction of the force, increasing the binding of the rock, to achieve rapid mechanized installation. May end anchor, anchor bolt and all extended, mainly for large deformation high pressure mine roadway support high-intensity, but also can be used for railway, hydropower and other projects of high strength, permanent roadway.
