True Latch brace is designed best for tension.  It technically would work nicely in a compression application also.  You would start the top bracket at the base of the threads and the direction of the brace placement on the gate itself would need to be reversed.  So, the bottom of the brace would attach at the bottom of the hinge side.  And the top of the brace would need to attach at the top of the latch side. However, it is still necessary to do a PRE-LIFT routine with the gate as per the instructions for the best outcome.
