SandwichBase, from the brand YY Vertical, is the clever support for installing a training beam without drilling into walls.
Its wood and steel system uses buttressing : once tightened in your door frame, the hold is stable and secure, including for dynamic pull-ups.
Its removable installation in 30 s (no tools required) and its compatibility make it an ideal tool in apartments, shared housing, rentals, and tight spaces.
Compact and stored flat, it disappears when the session is over. Adjust the horizontality if your door isn't perfectly straight and enjoy a 90 cm surface with a ratio designed for standard doors.
A simple and effective support, designed to let you train wherever you want, without any DIY work.
