kahlaan04 -> Suspension How To? (9/7/2008 7:47:46 AM)

I am looking for a guide if anyone knows of one on how to attach a suspension bar to the celing. I would like it to be able to support about 150 lbs. I have seen the bars on sale on many websites, but I am just not sure what else is needed to properly mount it. Thanks for any help.

If you want to do suspension, you're going to need it to support at least 10x that - there's static forces, and there's dynamic forces.

Static forces are the actual weight being held - in this case, 150 lbs. Dynamic forces are what happens when that weight bounces around, moves, or gets hoisted up or down. In the moments the weight is moving, sometimes it's pulling less than 150 lbs on the suspension rig, and sometimes it's pulling far, far more.

That being said, my preference has always been to build a frame from scratch. If you have 8 foot 4 inch ceilings (and most of us do), you can build and assemble an incredibly sturdy frame that will fit around your bed out of 4x4 wood posts. Even better, if you varnish it and decorate it a little with lace, it disguises perfectly as a canopy bed frame!

To truly attach to ceiling you need to anchor into the joists , the solid boards that run behind the roof material.
For proper anchoring you must allow for each anchor point to take the full weight
While you could use large enough screw eyes or eye bolts through the ceiling into the joists and it will take the weight it would be preferred to add additional bracing between joists to spread the load. This will allow for any over strain or defects in the joists.
I have used a single anchor (1/2in screw eye) into a open joist in my garage and lifted my 250 lb frame with out issues.

My preference is go into attic above room and drill through joist for eye bolt and us a large fender washer on top. While up there I will nail/bolt/screw a second 2x4 about 5-6 foot long parallel to the joist board for double strength as well as add several board between adjacent joists for side flex. Over kill but I do weigh 250+ and swinging motion adds to that.

One other option that is very nice is to buy a couple of pipe hanger channel (2in) or I-beam about 2in. 6-8 foot long each and then run across the ceiling anchoring to 5 or 6 of the ceiling joist with lag screws of adaquate size.

This will allow a variety of clamp on hangers (industrial) that will handle the weight and they can be moved or placed in a variety of locations to meet various positions of suspension.

Of course to blend all can be painted to match ceiling or black for accent.


industry has been hanging and suspending very heavy items for years. If you can visit a meat locker or packing shed and see how they are set up it is a fabulous method for suspension. I sadly missed a chance to buy a complete stainless tracking system from a local locker closure.

I am with Focus here, and I would add that if you can get an eyebold thru the joist, insure you add a second nut to jam it.  wouldn't want all that good work going to waste for lack of a nut.

That is a good starting guide.  A couple of corrections/additions I will add.  If the celling joists are part of your roof truss's they will probably be on a 24" center, not 16".  Another reason to go into your attic and measure.  I also recomend getting a 4x6" instead of a 4x4" because 4x6"s are cut to be beams, and 4x4"s are usually cut to be posts, the way the handle a load is very diffrient.

Dont use open eyebolts, welded or not.  Its not that hard to find a forged eye bolt, this is the only type you should use, end of story.  Open eye bolts are a piece of bent low grade steel, that isnt rated.  The piece of steel will try and revert back to its original form under stress.

You can probably complete this entire project for about 30-40 dollars, is it worth someones life to try and do it for less?

If you're not planing on suspending your sub... you don't have to worry quite so much.  I need some suspention bars just for balance when trampling.  But... I'll probably do as suggested above because, heck!  Why not get more than one use?

I guess I should have looked at it from a different angle. My husband is in the military, so not only are we moving every few years, but we live in on-post housing so we cannot really make many modifications to the house (such as drilling holes into the ceiling). Are there any free standing type alternatives that would not have to support 100% of the weight, but be used to simply hold a suspension bar elevated to lock wrist cuffs onto the ends while someone was standing and supporting their own weight?



FRSguy -> RE: Suspension How To? (9/11/2008 12:30:14 PM)

Yes, and you can make your own.
Some people build square or pyramid wooden frames that can support the weight. If you have an empty room that can be used as a dungeon for a few hours then its one of those things where you spend the morning or afternoon setting up your dungeon for the weekend.
Once your weekend of fun is over it gets torn down and converted back into a normal room. The problem is having an extra room...lol
I also rent, so I modify the rental property and cover it up with spakeling before moving.

There are lots of good portable rigs, and designs out there.  Remember when someone is "attached" to something, the device/furniture isnt always holding all the weigh, but it has to be able to.  Someone could trip and fall, pass out durring play, or something else.  Jay wiseman says that the highest percentage of bondage accidents are due to falls.  Just make sure your rig can support the weight incase something goes wrong.

There are many designs out there. As an example, you might want to take a look at this one -- very portable and incredibly strong.
