McNICHOLS® Trench Drain - POLYCAST® Frames

McNICHOLS stocks optional Frames and additional Installation Alignment Chairs for our Trench Drain System. For extra durability, Series 700 Hardnose Channel Frames (Kit A) can be inlaid on top of the Series 600 channel sections and fitted with cast iron grates (not included in Kit A). This additional frame adds more strength to the drain channel, helps protect the edges, supports the grates and is intended for heavier loading and traffic requirements. Additional Installation Alignment Chairs are also available.


McNICHOLS POLYCAST® Presloped Trench Drain Systems are designed for indoor and outdoor residential, commerical and industrial applications. POLYCAST® Trench Drain channels are made of a stronger-than-concrete precast polyester polymer concrete composite and are set in place prior to a slab pour. Our Systems are easy to install, durable, resistant to many chemiacals, and ideal for environments with extreme temperatures. The system is capped off with a removable slotted surface grate.
