Review on 🔒 COOLOGIN Adjustable Self Lock with 2000Lbs Capacity: Ultimate Versatility and Security by Mike Newbill

I use a pair of these to take up the sag on the double doors in my 35 year old warehouse which are constructed of rough sawn lumber and are quite heavy. I installed toggle clips between the 4X6 door frame header and the top edge of each door (near the door joint) to lift and align the doors so I can snap them back together. Works perfectly.
