Adjustable Spreader Bar by Sportsheets Edge

The spreader bar is a must have tool for the journeyman level bondage player.  Once you've mastered basic safety, consent, knot tying, and restraint, you'll want to graduate to open-wide immobilization.  It's beautiful, it's dirty, and for those submissives out there:  it feels so good to struggle.

Goddess and Piggy have a spreader bar, of course, for when he needs encouragement to spread his legs.

The BDSM MacGyvers keep a spreader bar handy because, gosh darnit, to get the position just right, sometimes you just need to apply some leverage.

Remember that the spreader bar can be used on arms, legs, or a mix of both.  Very versatile.

Here's what the manufacturers have to say:

Hoistable anodized aluminum spreader bar features nickel-free metal hardware and includes clips on each end and the middle to be used with edge wrist, arm or ankle cuffs. Expands from 28.5 in. to 37 in. and breaks down for easy travel. Features index lines for easy assembly.
