Restrict your submissive's movements using the Adjustable Expander Metal Spreader Bar with Cuffs which comes in black.

The bar is made of metal and its unique design allows you to adjust the opening 70 - 90cm giving you the ability to choose the width you want.

The cuffs can also be used separately as they are detachable so you can use them without the immobilizer bar and are fully adjustable for a perfect fit.

You can also use the ring on both ends to attach other bondage toys, such as ankle cuffs, to the spreader bar.
