All StreetBarbell devices are safe to handle, defy all weather conditions and are virtually indestructible. To keep the devices in place, the feet are fixed to the ground with 4 M16 x 125 anchor bolts each. Rubber protectors ensure that no one stumbles over it. Made for everyday use outdoors, the devices can be mounted under the same safety aspect indoors even with an optimum ceiling height of 280cm easily. Thanks to the unique weight system, the discs always remain on the device, which minimizes the risk of injury and ensures order in the field.
