Topic tags/keywords: heavy bag basement i-joists rafters heavy bag hanger rafter hanger floor joists question

Hello there,

I am trying to figure out how to hang my heavy bag on my finished basement ceiling. I just bought the house and there are some unfinished parts of the basement and I can see that it has I-joists with the web made of OSB. I was wondering how to go about this the safest way in that I don’t wreck the house.

I already read this thread:

..but I am not a construction guy and a lot of the terms are flying over my head. Also, the very last post by Nbeener doesn’t show the pics.

I was going to use this:

But since I have I joists, I am not sure if this will be feasible.

1. Is the OSB and the I-joist type of beam, in general, strong enough to hang a heavy bag on. My bag is approximately 100 lbs.

2. The pic shows regular beams and since the joists are I-joists, this would mean that there would be more distance from web to web, so I might have to reinforce it with some plywood, maybe? To cover the distance?

I’ve researched a few other methods as well such as the other one proposed by Nbeener where one could:

“use 2×6’s (or whatever), and build a platform across two of the joists, using long, beefy lag screws, and then hang the “standard” hanger from there.”



My worries with the plank across methods is that one would have to screw the plank onto the lower flanges of the I-joist vertically and I’m concerned if this would be secure enough.

I would appreciate any help. Thanks!


p.s. I’m sorry I couldn’t figure out how to link links and pictures. I tried a few times with no success.

The “trick” to introducing loads into a thin web is to add a member running from the top flange to the lower flange. This can be glued to each side of the OSB web and need not be directly attached to the upper and lower flanges. The technical answer is that the OSB web is carrying the load in shear and one needs to introduce the loads into the OSB web as a shear load. Look at where the joists are supported, there should be blocking running from the upper flange to the lower flange. Just try to duplicate this and you should be fine.

Have your say...
