Apparatuses and methods are disclosed for mounting conduits within spacers for underground installation. Spacers for side loading of conduit, as opposed to older methods of end loading, allow construction workers to easily assemble conduits to a plurality of spacers above-ground. The side loading technique uses spacers having bores that communicate with each other, preferably in a radial manner. Thus, a first plurality of conduits may be assembled or mounted to an inner portion of the spacers and then at least a second plurality of conduits may be assembled and mounted to an outer portion of the spacers. Cables later pulled through the conduits are typically those used for the transmission of electricity or communication signals. Other embodiments use bores that do not communicate with each other but are secured to the spacers with an outer banding saddle.
