LDB-U U-brackets are designed for fastening of intersecting channels.
Depending on their size, saddle brackets can be used for joining
LDBST 21 and 41 channel struts; LDB-U-82-3 and LDB-U-41-6 U-brackets
are suitable for 2 x 41 channel struts. The bolting on both sides of
the intersecting channels allows fabrication of joints rated at higher loads.
This solution comes very handy for building H-frames or racks
based on roof feet and supports.
