Master Series Dominion Bar

Spreader Bar, Collar & Locking Wrist Restraints

The Master Series Dominion Bar is a complete spreader bar restraint system for BDSM bondage scenes, built for dominant/submissive partnerships and couples who want real, inescapable control.

It pairs an adjustable stainless steel spreader bar with a lockable vegan leather collar and matching lockable wrist cuffs, all connected by heavy-duty carabiners and secured with real padlocks and keys. This is the kit you reach for when you want to take every last option away from your submissive and mean it.

Key Benefits

• Clip the bar across the front of the collar for a face-to-face power display, or lock it behind the neck to pin their arms back and leave their entire body open and exposed
• Real padlocks on every connection point mean nobody gets free until the dominant turns a key -- no wiggling, no slipping, no negotiating with a buckle
• Three independent lock points give the dominant layered control: hold all three keys or scatter them across the room
• Adjustable bar, collar, and cuffs accommodate a wide range of body sizes, from petite to large frames, with no makeshift modifications
• Nickel-free hardware keeps skin reactions out of the scene so nothing interrupts the moment
• Vegan leather construction looks and feels premium without using animal materials
• Two bar positions (front chest or behind the neck) create meaningfully different levels of vulnerability and exposure in a single piece of equipment

Safety & Care

Bondage Safety: Always negotiate the scene, establish a safeword or safe signal, and agree on limits before applying any restraints. Check in with your partner throughout the scene. Never leave a restrained person unattended.

Keep safety scissors or a key within easy reach at all times in case the scene needs to end quickly. Check regularly that cuffs and the collar are snug but not cutting off circulation. You should be able to slide one or two fingers under any restraint point. If fingertips tingle, color changes, or the restrained person reports numbness, release the restraint immediately.

Do not apply pressure to the front of the throat. The collar is designed for positional control and aesthetic restraint, not tracheal compression. Avoid any position that places body weight on the collar or bar in a way that could restrict breathing or blood flow.

Cleaning: Wipe all components down with a damp cloth after each use. Do not submerge the vegan leather, bar, or hardware in water. Allow everything to air dry completely before storing. For the metal bar and hardware, dry thoroughly to prevent oxidation.

Storage: Store in a cool, dry location away from direct sunlight. Keep padlocks with their corresponding keys together and stored with the kit so nothing goes missing between scenes. A dedicated toy bag or storage box keeps the full set organized.

Warnings: Do not use on anyone with circulatory conditions, neck injuries, or prior shoulder injuries without consulting a medical professional first. This product is designed for consensual adult play only. Inspect all hardware, carabiners, and lock mechanisms before each use and discontinue use if any component shows signs of wear, bending, or failure.

Discreet Packaging: Adult Toy Box ships all orders in plain, unmarked packaging with no product-identifying information on the outside.

Who It's For

The Dominion Bar is built for dominant/submissive partnerships and couples who want a restraint system that commits fully to the scene. If you have been using soft ties or basic cuffs and you want to step into something with real weight and genuine inescapability, this is the next level.

It works for people of all genders and body types. The fully adjustable bar, collar, and cuffs are sized to fit a genuinely wide range of bodies without any modification needed. It suits couples exploring structured bondage for the first time who want a complete system rather than piecing together individual components, and it is equally at home in the kit of an experienced dominant who wants a high-quality, versatile bar rig.

The two bar positions (front and rear) let you build meaningfully different scenes from the same equipment, making it a practical choice for anyone who wants variety without buying multiple pieces of gear.

FAQ

Q: What is the Master Series Dominion Bar and what does it do?

A: The Dominion Bar is a complete bondage restraint set that connects lockable wrist cuffs to an adjustable spreader bar, which then attaches to a matching lockable collar. The result is a full upper-body restraint rig that keeps the submissive's hands positioned at a fixed distance from their neck -- arms out to the sides or pinned behind the neck -- until the dominant unlocks them.

Q: Can the Dominion Bar fit people with larger necks or wrists?

A: Yes. The collar adjusts from 12" to 17.9" in circumference, the wrist cuffs fit from 5.25" to 9.6", and the bar extends from 25.1" to 33.25". The set is built to fit a wide range of body sizes without modification.

Q: How does the front vs. rear bar position work on the Master Series Dominion Bar?

A: In the front position, the bar clips across the submissive's chest with arms extended out to either side and the collar attachment at the center -- the dominant and submissive face each other. In the rear position, the bar locks behind the neck, pulling the wrists back and leaving the submissive's entire front body open and exposed. Both positions use the same hardware; you just reposition the bar and reattach the carabiners.

Q: Are the locks on the Dominion Bar real? Can the submissive get out without the key?

A: The padlocks are real, functional locks. Each cuff and the collar attachment locks independently with its own padlock. The submissive cannot remove the restraints without the key -- there is no backup release built into the cuffs.

Q: Is the Master Series Dominion Bar safe for someone new to collar and spreader bar play?

A: It can be, with preparation. Agree on a safeword before the scene, keep a key within easy reach, and check regularly that no restraint is cutting off circulation. Start with shorter scenes while you and your partner learn how the positions feel. 

Q: What is the Dominion Bar made of? Is the leather real?

 A: The cuffs and collar are made from vegan leather -- no animal materials are used. The spreader bar is stainless steel, and all hardware is nickel-free metal, which reduces the risk of skin reactions during extended wear.
