NOTE: Due to the weight of this product, expect higher than normal shipping costs. 

GF 21424 F Gray iron frames provide an ideal design option for poured trench drain systems by providing a preformed ledge for grates to sit on. The 2.63″H x 48″L frame holds a 2″ thick grate (grates not included). Built-in anchor holes help lock the frames securely into concrete during installation. (Rails are sold individually)

Purchase grates separately.

All raw gray iron grates begin to naturally rust with exposure to any form of moisture and will appear bright orange before settling to brown.
