There are a number of ways to make a secure mounting point for your sex swing. Listed below are some of most common methods. For more approaches I recommend visiting Abby Woods on YouTube and her sex swing channel.
The most important thing is to make sure you have secure mounting points. If you are unsure how to do this, you can hire an contractor to help.
Eye hooks can be purchased locally to match your installation requirements. The most important thing to remember if you choose to use eye hooks for your installation points, you must make sure you screw straight into the center of the ceiling joist. By putting a screw in off center or not straight may result in splitting the ceiling joist and make the hold much weaker without you being able to see it.
Additionally if you select an eye hook mount screwed into your ceiling joist, you can not remove and re-install the hook in the same hole because it will weaken the hold.
Sex Swing Stand
The Sex swing stand is is a great option that requires no technical skills but does require the purchase of a stand.
Beam or Branch Installation
A popular way to install swings is to use an exposed beam in your house or even a branch on a tree outside. For each mounting point just hang a rope over the beam and mount the swing to that.
