Ceiling – Hang a 100lb heavy bag from ceiling

ceiling

I'm trying to figure out the safest way to hang a 100lb heavy bag from the ceiling in my garage.

The pictured part is under a bedroom, and the continuous line, if it's like the part that is under the attic has a 1.5inch wide piece of wood. The other half of the garage does not have any of the perpendicular beams.

From what I've read, I can't just hang it with a single eye bolt, and I don't have access to the other side because of the room above. I found this TuffRail system, but I'm not convinced that it would be structurally sound. I also found this SpiderMount, but the spacing of the larger beams doesn't match.

Is it possible to safely hang the bag?

So a 100lb bag getting rocked by punches may be disturbing to whoever is upstairs it's not all that heavy for the structure. A single drywall sheet is around 50 pounds or so(not going to google exact weight). So the issue is fastening to the ceiling. I like the second one you posted because of the springs. I would fasten some light duty metal square tubing across the span of the joists in such a way that I could bolt the spider mount to the metal.

With this method you can run the tubing across several joists spreading the load so over time they won't sag.

I think your joists run this way and in the method outlined above the metal tube would run perpendicular to the joists spanning 3 joists for redundancy. enter image description here
