The hidden bracket is
the standard connection for Version 1 RK FRAMEWORKS®
beams. The hidden bracket can be detached and reused. The steel
insert fits in the hollow beam sections and forms a secure grip
for the hidden bracket. This design uses material only where
needed for less weight. Surface contacts are moved from the center
to peripheral areas to increase mechanical strength.

The special RK tapered
screw supplied with the dynamic hidden bracket connector provides
clearance gap where it screws into the end of the beam to allow
flexible movement of the joint. This design reverses dynamic
stresses due to temperature and vibration as the joint does not
tear the aluminum beam apart during movement. |

Large contact area for
automatic alignment of both beams. |

Hidden bracket design
provides a strong invisible connection. |
