will be mounting it. Ensure that the pipe surface is smooth without any raised areas
(seams, etc.) With a pencil, marker or chalk, draw a generous rectangle around the
bracket. Clean and de-grease the area within the rectangle. Use the small sanding block
provided with the installation hardware as necessary to remove any grit, corrosion,
rust, loose paint or other contaminants. Be sure to wipe the surface clean after sanding.
The cleaned surface should extend at least ½” beyond the length and width of the
mounting bracket.
