The LU replaces four conduit bodies -- LL, LR, LB and C -- in most applications. Rated for a 40% wire fill, it will not de-rate your conduit system like other conduit bodies. Wires can be pulled through it, reducing installation labor, and wires can be spliced within the body because it is UL listed as an electrical box.
