Suspension rig

A suspension rig is the physical infrastructure that makes suspension bondage possible. It includes whatever is used to anchor the lines that bear the suspended person’s weight: a free-standing A-frame or H-frame of steel or hardwood, a purpose-built ceiling mount with load-rated hardware, or structural anchors in a rigging-equipped dungeon or studio space. The rig does not include the rope or the person — it is the load-bearing environment within which the scene takes place.

This entry addresses what a rig is and what it requires. Suspension technique itself falls under the activity pages for suspension bondage and related entries.

Why the structure matters

Suspension puts the full body weight of a person onto a set of load-bearing points — both on the rig and on the body. A 70-kg person suspended from a single overhead point is loading that point with 70 kg at rest. Dynamic forces during position changes, struggling, or swinging can briefly multiply that load by a factor of two to four. Hardware, anchor points, and the structure itself must be rated to handle these forces with significant margin.

This is not theoretical. Rigs constructed from inappropriate materials — closet poles, drywall anchors, plumbing pipes, or other household hardware not rated for dynamic load — fail. When they fail with a person suspended, the consequences are falls, acute injury, and potentially worse.

A purpose-built suspension rig uses materials and hardware with known load ratings, adequate for the expected dynamic forces with safety margin. Common materials for standing rigs include steel tube, heavy hardwood, or engineered lumber. Hardware — shackles, carabiners, swivel mounts — should be rated for climbing or rigging rather than repurposed household or decorative items.

Types of rigging structures

Free-standing frames — A-frame, H-frame, or X-frame designs that stand independently and are loaded from above. The most common setup for people who practice at home. Must be stable under dynamic load — cross-bracing and wide footprints matter.

Ceiling mounts — hardware secured to structural joists (not drywall or decorative beams). Load-rated eyebolts, ring mounts, or purpose-built suspension points. Requires understanding of where structural support runs in a ceiling and the use of hardware actually rated for the intended load.

Dedicated dungeon/studio infrastructure — rigging-specific steel bars, I-beam drops, or purpose-built overhead grids found in kink venues and professional studios. The most reliable option for those without the knowledge to assess structural loads themselves.

EMT shears are mandatory equipment

Every suspension scene must have EMT shears (safety scissors with a blunted lower blade) immediately accessible — within arm’s reach of the rigger, not across the room. If a suspended person’s circulation is cut off, they lose consciousness, their safeword becomes unavailable, and their weight on the lines becomes dead weight creating more compression. The only safe exit in an emergency is cutting free quickly.

This is not a suggestion for advanced practitioners. It is a baseline condition for any suspension scene at any skill level.

Why suspension is not for beginners

Suspension is one of the activities most consistently categorized as edge play — meaning it carries inherent risks that cannot be eliminated entirely, only managed through knowledge and preparation. The risk is not in the rope; it is in the combination of load forces on joints and nerves, circulation restriction under compression, the time required to safely lower and free a person, and the consequences of structural failure.

Nerve compression during suspension can cause temporary or lasting nerve damage if not identified and responded to quickly. Common danger zones are the brachial plexus (armpit area), the radial nerve (inner upper arm), and any tie that crosses a joint under load. Sensations of tingling, numbness, or weakness in hands during a scene are emergent signals — the position must be changed immediately.

The path to suspension goes through floor rope work, building knowledge of how rope interacts with the body over many sessions, and learning from someone with direct experience — not from reading alone.
