Cross Bracing Solutions



As solar installers try to minimize the number of penetrations on rooftops, and therefore increase the span distances between vertical supports, the issue of cross bracing becomes exceedingly important.

Solar Cross Bracing Solutions

Hollaender has a series of fittings that can be used to attach cross bracing sections in a pipe rack.


The #17 Adjustable Elbow is a 2-piece fitting that is adjustable across a broad range of angles. The male (M) part typically attaches to the vertical post and the female (F) part attaches to the cross brace member. Until now, these have only been available in the same size for both parts, i.e. 2” IPS - 2” IPS, or 1-1/2” IPS – 1-½” IPS.


We have now developed reducing fittings, so that one can attach a 2” IPS vertical to one or even two sizes smaller.


The following chart shows the list of these fittings available:
