Key points
- Use hardware with a stated working load limit, not just a breaking strength
- Never improvise overhead anchor points
- Overhead hard points need professional installation into structural beams
- Every setup needs a release that works within seconds
In detail
- The working load limit (WLL) is the load the manufacturer allows in use. Breaking strength is much higher and is not a figure to plan with
- Dynamic loads: struggling, swinging or a sudden drop can briefly put several times body weight on a point. Plan with large margins
- Not anchor points: curtain and shower rods, door frames, light fittings, pipes, sprinklers, banisters and ceiling hooks or eye bolts without a rating
- Overhead hard points: installed by a qualified person into a structural beam, with hardware rated for the load. Drywall and suspended ceilings cannot carry people
- Floor and bed restraint (under-mattress straps, door anchors that only hold limbs, tie points on furniture) carries less risk, because the body is supported
- Crosses, benches and spanking horses: check weight limit, stability and padding. Bolt tall frames to a wall or the floor so nothing tips when someone pulls
- Positions: standing restraint can lead to fainting. Do not keep arms above the head for long, and make sure the person can be lowered quickly
- Suspension is a separate skill. Learn it in person from experienced teachers, not from videos
Warnings
- A failing anchor can cause falls onto the head or neck
- Never leave a restrained person alone, not even briefly
- Retire hardware that has been dropped hard, bent or loaded beyond its rating
- Consult a structural engineer or qualified tradesperson before installing a hard point
