Blackburn 3907BU – Frequently Asked Questions
1) What size water pipe does the Blackburn 3907BU ground clamp fit?
The Blackburn 3907BU is sized for 8 inch water pipe. It's a single-size clamp, so if your grounding electrode is a smaller diameter service main, you need a different catalog number in the series rather than this one.
2) What does "direct burial" mean on the Blackburn 3907BU clamp?
Direct means the clamp is suitable for direct burial, so it can be used where the water pipe electrode connection is underground or in earth contact rather than only in an accessible dry location.
3) Is the 3907BU pipe ground clamp bronze, and does that matter on a copper water main?
Bronze is the conductor material on the 3907BU. Bronze on a copper water pipe keeps the metals close on the galvanic scale, which is why bronze clamps are the standard choice for bonding to a copper or brass service main.
4) Is the Blackburn 3907BU made in the USA for a Buy American job?
Country of origin on the 3907BU is the United States, which is the line a public-works or federally funded project submittal usually asks for on grounding hardware.
5) Does the 3907BU ground clamp come insulated?
No. The 3907BU is a non-insulated clamp, bare bronze with no coating or cover, which is what you want for a bonded metallic connection to the pipe.
6) Is the Blackburn 3907BU sold individually or in a box?
Sold each. Order the quantity of clamps you need, one per connection.
