A secondary drain pan sits underneath your indoor evaporator coil or air handler. If your primary condensate drain line ever clogs, this pan catches the overflow and routes it to a secondary drain — preventing water damage to ceilings, floors, and walls. Required by code in most attic and closet installations.
Specs: 35″ x 31″, galvanized steel, drain connection on the 35″ (long) side
Replaces: DP3531
Fits: Universal — sized for 2.5- to 3-ton air handlers and evaporator coils
