Hollaender 1-1/2″ adjustable elbow Tee-E assembly (No. 17E) that can be used with standard pipe for solar panel ground and roof mounting systems.

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

The Hollaender #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 – 1-1/2” IPS.


Hollaender® fittings, when torqued to the settings indicated have the following support and holding strengths when attached to galvanized steel pipe:

Fitting size Torque (ft lb) Holding and support force w/2 set screws Holding and support force w/1 set screw
1-1/4″ IPS 14 2000 lb 1800 lb
1-1/2″ IPS 17 2350 lb 1850 lb
2” IPS 17 3200 lb 1925 lb
