Neenah Foundries Co. Type S Frame SystemNeenah’s R-4996 Self-Forming Trench Pan combines the endurance of Neenah Foundry grates with a modular trench drain.

The 8" and 10" wide R-4996 Systems offer a 30" long cast iron channel, which becomes the trench lining after installation.  The 12" wide R-4996-C and aircraft rated R-4996-CA feature 36" long lengths, meaning fewer parts for a faster installation.

Choose from among end outlets, bottom outlets and side outlets to fit 4", 6" or 8" pipe.
