The FSR FL-GRD2 Pour Pan is the answer to floor box installations that are on grade. If your application is a poured concrete floor, but the box may rest on soil, rock, gravel, etc., you must first install the Pour Pan. The Pour Pan is set into the grade below the floor box and allows concrete to flow around and under the box to prevent the floor box from contacting the grade. The unit comes with extended length leveling feet, and the unique "pan wings" prevent the pan from shifting during the pour.
The FL-GRD2 and FL-GRD4 Pour Pans are two different depths. Select the appropriate model based on the thickness of the pour and the depth of the floor box to be installed.
The FL-GRD200 is a smaller version Pour Pan that has been added to the line to accommodate the new FSR FL-200 floor boxes. Great for installations that are tight on space.
The pan is designed to provide a minimum of approximately 2" of concrete under the box. Select which model pan is used based on structural and site requirements.
A simple formula for selecting the proper Pour Pan:
Depth of Box + 2 minus the depth of the pour = Pour Pan model.
Example: Installing a 4" deep floor box into a 4" concrete slab. (4+2) - 4 = 2. The proper model would be the FL-GRD2.
Example: Installing a 6" deep floor box into a 5" concrete slab. (6+2) - 5 = 3 (round up to 4).The proper model would be the FL-GRD4.
