This tank cleanout cover closes the 24″ x 36″ opening of a SteelFront rectangular cleanout frame. It is a 28″ x 40″ steel plate punched to match the frame’s bolt holes, so it lines up without drilling. Seal it with a strip of 2″ neoprene gasket.

Options

Thickness Size Weight Price Lead time
1/4″ 28″ x 40″ 79 lb $177.81 Standard
3/8″ 28″ x 40″ 118 lb $264.83 3-5 business days

Both covers ship raw steel and go by freight because of their weight.

1/4″ or 3/8″?

A 1/4″ cover is lighter to lift and costs less, which suits smaller and lower tanks. A 3/8″ cover stays flatter under liquid head and repeated bolting, which suits taller tanks and covers that are opened often. Follow your tank design.

Questions

Will it fit another brand’s cleanout?
Only if the outside size and bolt pattern match. It is made for SteelFront frames.

Is the frame included?
No. The cleanout frame is $85.72 and sold separately.
