Ouch! Black & White Door Restraint Kit

Setting this up took less than a minute, just slide the acrylic tubes over the door, shut it, and you're good to go. The cuffs hold up way better than I expected once everything's locked in place.

Wasn't sure the tubes would hold steady on our hollow door but they lock in solid once it's closed. The acrylic is thick and smooth, no sharp edges anywhere near the cuffs. Ended up being way more fun than I expected for something that stores flat under the bed.

Set up took about a minute: the acrylic tubes just drop over the door and you close and lock it. They don't budge even when things get rough. Way sturdier than I expected for the price.
