Bolt Stand-Off (BSO)

Create a water-tight repair around damaged penetration fittings by sealing to the sump wall around the fitting, and a clean section of pipe inside the sump. Used in tandem with the SRB Series split repair fittings, a repair solution is available for most situations. These repair fittings can be installed on both plastic ​and fiberglass sumps; options are available for most types of pipe.


Use the small BSO for conduit and small diameter flex pipe. The large BSO will cover rubber penetration fittings for rigid pipe and larger diameter flex pipe.
