I have used that boom a lot. We set 24 foot LVLs on an 18 foot tall stage and just erected a 165 foot long storage building with 16 bays in it. We fabbed the walls at my shop and set everything with the boom and had the rough framing and trusses done in two days!! Your service and shipping time was top notch. I do not have one complaint about the boom. I am attaching a pictures of the boom in use.
