SolarMount Top Mounting—Faster Than Ever With T-Bolts

UniRac introduces T-bolt to further speed installation using its top mounting SolarMount system for racking photovoltaic arrays.

The fastest, easiest way to install a PV array is getting faster and easier. In June, UniRac will begin shipping T-bolts with our top mounting SolarMount systems.


T-bolts replace 1/4-inch hexhead bolts used with top mounting clamps to secure PV modules to the rails. They drop into the module mounting slot—anywhere along the length of the rail. The bolts capture with less than a quarter turn.

For example, rails that hold four 150-watt modules are typically 15 feet long. Instead of sliding in a hexhead bolt from the end of the rail, an installer can quickly drop in a T-bolt wherever it's needed.

The rail and T-bolt combination has undergone destructive laboratory testing at the University of New Mexico's Department of Civil Engineering. It remains UBC compliant when installed in accordance to UniRac's code-compliance documentation.

As with many recent UniRac innovations, this upgrade takes place with no price increase or model number change. All CT Series top mounting clamp sets will include T-bolts within two to three weeks.
