As of March 2020, we are sold out of door anchors and the MB2 does NOT ship with a door anchor until noted on our product page. So you either need a hardware mount to a joist or stud (like a large bolted O ring) or an overhead setup like a beam, branch, pullup bar. We do expect to have more anchors in stock at some point in April and it should be noted on our site.
MB2-normal can be used indoors as long as you have the door anchor. Our initial incarnation included a case that doubled as a door anchor. As we've received input, that vision has evolved and we now use a different style door anchor with a new case coming soon after! The new door anchor now automatically ships with any purchase of any regular MB2 set, nothing is needed on the monkii end, the warehouse simply adds it to each order! It is designed similar to the pocket monkii anchor but has a sweet monkii carabiner to clip the MB2 straps into.
The tactical MB2 DOES NOT include a door anchor. As specified on the order page, it is for outdoor and/or gym station use and designed to utilize the tactical workouts, which are very challenging and require and overhead setup for the pullups and dips and other moves you cannot do on a door.
Handy monkiis can also use O rings and wall anchors from home improvement stores as long as they go into joists or studs.
If you have questions on the differences, or using MB2 indoors, please shoot us an email or webstore message.
