The riser kit also has a means to secure the collar extension to the grease interceptor. Also disclosed is a latch assembly for securing a cover onto a container, the latch assembly comprising a catch member secured to the container transverse to a container wall at an upper end thereof, a latch member pivotally mounted to the cover adjacent an edge thereof and positioned to register with the catch member.
