LDB-BAN-R2 double adjustable channel brace feature two holes
in each of the two articulated legs and two holes in the base channel.
The legs are bolted to the base channel to allow a smooth
adjustment of the angle between the channel struts and the base channel.
The double adjustable channel brace comes handy whenever there are
inclination differences between the support points, or whenever
you need to set a channel strut at a non-standard angle.
