A channel with sliding clamp and rod arrangement for leveling a ladder comprising a base unit of a hollow rectangular shape adapted to fit over the leg of the ladder. The base unit has interior walls spaced apart sufficiently to accommodate the ladder leg. Each of the walls has formed thereon a plurality of spaced splices that slop outwardly and downwardly away from the ladder leg. A clamp member comprises a generally rectangular block that has formed thereon sloping splices that fit into the grooves or spaces between the splices of the base unit. Clamp member has a bore that adjustably and securely retains a support rod, which has a swivel foot at one end. The end of the clamp member that is to be placed adjacent the ladder leg and the opposing interior surface of the base unit have a substantially V-shaped configuration to insure slip free purchase against the ladder leg.
