How is it easier to fit than a normal bolt fixing??
You still have to mark and drill four holes, then fill it whatever you decide.
Yep, drill four holes, but if your out with the bolt fixings & you come to fit the gun cabinet, it can be a bit awkward lining the holes up. But with the chemical resin you just put your cabinet against the wall, mark the holes, drill them, put the cabinet back on the wall/lined up with the holes, squeeze the resin in, push the threaded bar into the holes, let it set, then tight the nuts to keep the cabinet onto the wall,
