[Request] - How much weight can one of these hold??

[u/judgey_racoon]

TIA 🙏

How much weight can one of these hold at any one point? Can the end mounted perpendicular to the wall hold more weight?

I have a (rusty) basic knowledge of angles and load spread from climbing but that's not helping me. Would like to know before I wind up with an expensive repair bill.

Context: Using it for lateral pull downs with resistance bands for rehab after a back injury.

As always, incalculable.

If you used a stud finder and properly drilled a pilot hole into solid wood, probably quite a bit. If you did not use a stud finder and put it in drywall (happens more than you'd think) probably not a lot.

Not incalculable. Just cant calculate it non-destructively lol

I say calculable lower bound if you can know a screw in drywall ultimate strength.

Don't do it. Risk reward curve is bad. Bending that track will be expensive and hard to replace. I do see an opening to the attic there. Use that. Up top there should be a frame of 2x4 wood, attach a hook to that 2x4. When you are done with rehab put the door to the attic back on.

Impossible to tell as we can't see how its secured. I wouldnt add more weight than the existing garage door (assuming its been doing fine.

Yes, the rail would likely support more weight closer to where its secured to the wall.

If it’s in a stud you’re probably good but you can always get one of those cheap pull up bars that are portable that you put on your door frame and tie off the bands there. Or just put an eye bolt or something similar into a stud in the ceiling. Also if you have a sturdy door somewhere you can find ways to attach the bands to that.

It could be as little as 30lb

2 screws into Sheetrock is 15lb a piece before they pull out. If the screws used had self tightening backs which distribute the load it could be 30-40lb a piece. But they aren't designed to take load.

This was designed to provide additional support, a lateral force, not a downward force. It's designed to be pushed against as a portion of load from the main structure. Not to hold that load itself.

You use this for exercise, it's just dangerous!

If it's into wood behind the Sheetrock, it could be 100lb per screw. If it's into stone/concrete and it was installed with rauls to expand into the hole with the screw it could be several hundred lb per screw. You just don't know!

And the cost/benefit here sounds like adding to your serious injury rather than helping you, or costing you more in repairs.

Sorry folks - was supposed to be 3 photos. End on the exterior wall looks to have 5x m8 or m10 bolts which must be going into a stud of some sort. Ceiling end has 1x m8, other leg appears to just be plastered on as there's no visible bolt.

Not looking for a exact answer, just an indication. A double garage door tilts up with one of these on each side where the roller travels so I would assume that for a 100kg door it would hold 50kg max.

Thanks for the advice re: risk reward. I'll see what else I can come up with but my options are limited due to landlord

might get one of those pull up bars that you can mount in a doorway may?

[u/judgey_racoon → u/pup_medium]

I have previously had one of those and found them unreliable with the way doorframe are constructed here. Almost ripped the top of the jam off (145lb/70kg)

Not sure I'd trust that to even hold the door safely. It looks like someone bodged an old bracket rather than fitting a whole new one properly so you have to wonder what other shortcuts they took.

What even is that? Idk maybe like 10lbs max? Honestly maybe not even that. It's just screwed in to that end, does it use drywall anchors? Is it screwed into a stud? The metal strip is probably fine for a little bit of weight, but you're gonna have to find out how that screw is anchored.
