  • Headwall for drain pipe
    Publication number: 20040081517
    Abstract: A sectional headwall (10) for a drain pipe (72) includes a unitary base member (12), a unitary sectional member (14) positioned on top of the base member (12), and a unitary lid member (16) positioned on top of the sectional member (14). The unitary base member (12) includes two longitudinally extending walls (42, 44) and two end walls (46). The base member (12) further includes a sleeve (48) extending between and connecting the longitudinal walls (42, 44). The sleeve (48) defines an aperture (50) extending through the longitudinal walls (42, 44) for receiving a drain pipe (72). A drain pipe adapter (80) may be inserted into the aperture (50) to accommodate different sized drain pipes (72).
