A locking latch assembly for a twistlock assembly that is adjustable over a range of heights of a load level of the twistlock assembly relative to a deck level includes a base bracket configured to be secured to a housing of the twistlock assembly, and a swing latch having a central slot. An axle passes through the base bracket, the swing latch being secured around the axle to allow the swing latch to swing relative to the base bracket. At least one pin is secured on the base bracket, the at least one pin engaging a first surface of the swing latch when the swing latch is in a substantially vertical locked position in which the swing latch is at a first angular position relative to the base bracket, and engaging a second surface of the swing latch when the swing latch is in an unlocked position in which the swing latch is at a second angular position relative to the base bracket. The at least one pin is configured to be disengaged from the swing latch to allow the swing latch to swing relative to the base bracket. The slot of the swing latch has a width sized to allow a T-handle attached to a T-shaped locking pin of the twistlock assembly to pass therethrough and to be substantially restricted from rotational movement while the swing latch is in the substantially vertical locked position, and has a length sized to allow the T-handle of the twistlock assembly to pass therethrough throughout all of the range of heights of the twistlock assembly.
