Double Lok Bolts - Minova Global
Minova Double Lok Bolts do not require any special tools or installation techniques. Instead, when used with the proper Minova resin, the expansion shell of the Double Lok Bolt sets the initial anchorage and allows the resin to cure in a state of compression.
Additional anchorage for this system takes place along the interface of the bolt shaft, resin and borehole wall. The “combination anchorage” of the expansion shell and resin has proven very successful for adverse ground conditions.
