Top Cap

Our heavy duty cast aluminum IronRidge Top Caps secure quickly and easily to galvanized schedule 40 pipe (ASTM A53 Grade B) or mechanical tubing (i.e. Allied Flo-Coat, Gatorshield, Gatorshield-Plus) piers with 2 set screws.

Available in sizes that fit either 2” or 3” steel pipe and mechanical tubing, the top cap supports cross pipes with U-bolt hardware.

The top caps are manufactured using cast aluminum ALMAG 535 and come with a mill finish. As a reminder, the substructure pipe and mechanical tubing are not included.


All IronRidge Systems have been listed to UL 2703, the standard for evaluating solar mounting systems. This ensures they maintain strong electrical and mechanical connections over an extended period of time in extreme outdoor environments.


IronRidge products come with a 25-year warranty, guaranteeing they will be free of defects in materials and manufacturing which materially impair the use of the products for the purposes for which they were designed.
