Ceiling Mounts

tarthrin · Jul 8, 2011

So I was thinking of adding some ceiling mounted hooks above the "play area" aka the bed. The idea is just a slight twist on the normal spread eagle tie, with arms/legs pulled more upwards.

*** I am not planning for this to be suspension play, I will never be suspending my partner via whatever I come up with.

However, I still want it to be fairly sturdy, there will be plenty of jostling and such on the hooks. I can find all sorts of decent anchors that go through drywall or go into brick with load ratings. I can't find anything that looks like it will anchor well into just a wooden ceiling joist.

What would be even better would be to have a threaded insert into the ceiling, so that the hook can be removed and replaced for a move discrete bedroom fixture.

Perhaps something like this, but for wood.

I do not have access to the attic, as we live in an apartment. Otherwise I would have a lot more options.

Has anyone done anything like this before?

You need something that can go directly into the joist. The little drywall anchors will not be enough. With all the pulling and weight that will be on the eye bolt you will need something into the wood. Drill a hole into the joist a little smaller than the eye bolt and screw the eye bolt into the hole. Test the eye bolt by stringing some weight onto it before using it on your subject. If all holds up have fun!

Check out what I found!

They are threaded inserts with a wood screw anchor. I may try one of these.

The other option I came up with today was epoxy with a regular threaded insert. They have anchoring specific epoxy:

I am leaning towards the Sammys Wood Anchors.

I thought about just getting a regular screw in eyebolt, but wanted to do more research to see if I could find something easily removed/covered up.

If I go with these Sammy anchors or epoxying an insert, the only thing left to find is something that can discreetly cover them when not in use.

What you're looking for is has wood threads on the outside and machine threads on the inside. I've seen something like that somewhere, but damfino where, or what they were called, though "anchor" or "insert" is probably in the name somewhere.

If you have a Fastenal store nearby you might drop by and enquire. Tell them you have some fairly heavy hanging planters and you want something discreet so you can just unscrew the eyebolts when you move out.

You're probably going to be going into a 2x joist, which is 1-1/2" wide. You don't want anything with an outside diameter much over 1/2". The threads for the eyebolts can be 1/4" or 5/16". You'll need to drill a pilot hole to take the insert, so you'll need the right size drill bit. If the pilot hole is too small the insert will just split the ceiling joist.

Top just did this last week as a surprise to me while I was on vacation. I'll ask him to take some pics and explain how he did it tonight when he gets home. I really enjoy them!
